Pumps in mining

Mine dewatering is arguably one of the key challenges to production and efficient draining of the water or sludge is a key component of timely and optimal production.In addition mines are also used in the mining process itself such as in the transportation of froth flotation and slurries.

In the market today there are several manufacturers who produce pumps which are ideal for this kind of work.

Preferences lean towards size and even ease of maintenance. Robustness is essential in any pump in order to withstand the harsh environment and rough handling that it will have to endure and ease of use is also critical because no one wants to walk around with a 600 page user manual in one hand while trying to carryout the drainage process.

Different pumps are also suitable for different applications. There are submersible pumps, centrifugal pumps, screw pumps, and peristaltic pumps to mention a few and each has its own advantages and disadvantages.

Efficiency is a catch all phrase in pumping that refers to the energy consumption during operation at a given flow rate as well as the ability to stop and start automatically once a desired level is attained. It is something to keep note of.

Remember that all manufacturers tout their pumps as being long lasting, durable and highly efficient but one would be advised to also look at after sales service and availability of parts as well.

Environmental Pumping Solutions Ltd

They are a UK manufacturing company to ISO 9000 standards, designing and manufacturing their own range of high quality peristaltic hose pumps.

They also manufacture high quality replacement peristaltic hoses, lubricant, clips and shoes suitable for ‘all and any’ other brands or manufacturers of peristaltic hose pumps on the market. They now supply many of the leading peristaltic pump manufacturers in the world and are fast becoming the peristaltic pump industry’s preferred hose manufacturer. Whatever make of peristaltic pump you have, they can supply the hose and provide excellent advice to ensure you maximize the life of the hose they supply.

Peristaltic Pumps are used commonly in literally thousands of applications like Chemical Industry –

Viscous and/or abrasive sludges, corrosive chemical dosing or transfer, sheer sensitive chemicals, general waste pumps, Chemical injection, Cement transfer, Mining waste transfer and Waste Water treatment industry – Sludge pumps, desludging, metering pumps, lime dosing, sewage/sewerage pumps just to mention a few.

Their peristaltic pumps are taller and wider than the industry standard and therefore the distance the roller is in contact with the hose is much greater creating an increased flow per revolution. This means their pump will run at half the speed of a standard pump, provide twice the hose life, yet produce the same output.

Melanie McLean from Environmental Pumping Solutions says that they sell their products directly to the African market, she also says that this is a market they would wish to delve deeper into.

Libra Fluid Equipment Co., Ltd

They are professionals in Slurry pumps and Fluid solutions in various industries, such as mining, metallurgy, coal, power, petroleum, chemical, municipal, environmental and other conditions.

Slurry pump parts that are interchangeable with Warman Slurry pumps are also in their range. If you are looking for an alternative pump parts supplier, with high quality parts which don’t require you to change your current stock holdings, perform as the original manufacturers’ equipment, and at a fair price and lead time, you’ve come to the right place!

At Libra, they build a wide selection of quality engineered highly reliable and truly innovative slurry pumps to help their customers to maximize the return on their overall investment and reduces critical parts stocking costs to an absolute minimum.

One of their products the H series Centrifugal Slurry Pumps are designed for handling highly abrasive, high density slurries in metallurgy industry, mining industry, coal, power, building material and other industrial departments. The pumps of this model can also be installed as multi-stage series.

Samuel, the sales manager at Libra says that their products are available in Africa but they are currently looking for suitable agents. He advices buyers to check the working conditions and know the requirements clearly before selecting slurry pumps.

Dowdens Pumping & Water Treatment

They are an Australian pumping and water treatment organization with over 40 years industry experience that operates primarily in the mining, industrial, commercial, agricultural and domestic industries.

After a two years process of research and development into efficient mine site dewatering and high wall pumping operations they designed and manufactured the HDS200 dewatering system. The foundations of the HDS200 are based on industry identified needs, requirements and improvements from end users of pumping equipment in the mining industry. From all parts of the globe, including South Africa, Chile and most importantly Australia, the input from the end user was a key factor in the final design. This broad range of feedback into what is required in a high wall pump has resulted in the development of the most advanced high wall dewatering system available, capable of delivering 200L per second at 100m head.

The HDS200 features a comprehensive list of innovative design elements which include a towable design, hydraulic wheels and a tow hitch which allows the unit to be towed on wheels or pushed on the skit base. Hydraulic radio control back to base remote monitoring and colour screen with intuitive system control diagrams, 4,000 litre fuel reservoir, Twin 120m x 180mm PN16 Poly Pipes, four wheel tandem axle on wet end to assist when traversing high wall and capability of 200 L/Sec @ 100m and 300 L/Sec @ 80m head.

Their use ranges from the provision of high quality filtered, softened and pathogen-free water treatment plants for haemodialysis systems used in medical industries, through to rotating biological contactor sewage treatment plants suitable for mine sites as well as fully plumbed 40ft skid-mounted containerized potable water treatment plants used in remote communities, construction and mining camps.

Managing a precious resource – dewatering for African mines by Polypipe

In designing and implementing effective mine dewatering systems, mine operators are taking a crucial step in ensuring the long-term functionality and profitability of a mining facility. With many mines producing thousands of gallons of wastewater per minute, systems capable of coping with considerable volumes of pressurised water, which may contain abrasive particles as well as chemical solutions, are essential in keeping a mine operating at optimum capacity, as well as protecting the surrounding environment from potential contamination. Philip Wood, Export Sales Manager for Polypipe, the UK’s leading manufacturer of plastic piping and water management systems looks at the options for African mines.

Any dewatering system will need to take into account not only the projected usage of water by extraction procedures at the mine, but also the local climate and environment. If a site is prone to frequent or seasonal flash flooding, which could cause a tailings pond to overflow, additional capacity need to be planned in. Proximity to rivers and other water courses, either above or below ground, will also require a more sophisticated system. Extensive field testing, to examine a site’s hydrogeology and climate and assess the possible impacts of ineffective dewatering or accidental overflow, is therefore essential and should be completed as early into the planning of a mine as possible in order to gain the relevant permits. Consideration must also be given to the welfare needs of mine personnel – water for drinking, cooking and bathing must often be pumped in and stored on site, so care must be taken to ensure this fresh water cannot come into contact with mine wastewater in the event of excessive rainfall or equipment failure.

Both open-pit and sub-surface mining operations require effective dewatering systems, which provide more benefits than simply removing excess water from working areas. When undertaken efficiently, mine dewatering also ensures the stability of mine walls by preventing erosion, reduces wear and corrosion on drilling equipment and other machinery, and improves workplace health and safety. Properly controlled mine dewatering also helps protect the surrounding water table from contamination, protecting local ecosystems and maintaining clean drinking water for surrounding communities.

While pumps, valves and sensors are the most high-profile aspects of mine dewatering systems, the whole infrastructure can collapse if not properly supported by appropriate pipework. In fact, systems relying on weak pipework without the required capacity can cause pumps to burnout increasing operational and expensive downtime costs.

In order to cope with water being pumped from a mine, particularly where it must travel up an incline or must be removed rapidly, the ability to cope with pressurised water is a key requirement for dewatering pipework. As a major use of water in mines is in the excavation of ores through erosion and wet drilling, wastewater will inevitably contain sand, grit, rock fragments and other abrasive material which is generally not removed until the treatment phase of mine dewatering. Pump these slurries from a mine at high pressure and their abrasive properties are amplified, adding to the strain placed on pipework systems. As well as the capacity to stand up to abrasive particles, pipework must also be resistant to chemical corrosion or softening.

For mine dewatering systems, polyethylene (PE) is an ideal solution. Its resistance to chemicals enables it to withstand even the most aggressive acids as well as abrasive particles. PE pipes have significant inherent strength and impact resistance. They can be installed both above and below ground and can cope with temperatures in the range of -40ºC to +60ºC. The extremely smooth bore of PE pipes offers reduced friction – meaning, less drag and turbulence when large volumes of water are transported at high velocity. PE pressure pipes can be jointed using butt-welding or electro-fusion techniques to form a continuous homogenous pipeline which affords no chance of leakage.

Specifying the correct pipework and subsidiary storage can optimise the effectiveness of a mine dewatering system, cutting down on maintenance costs for the pipework itself as well as pumping machinery. PE in particular is ideally suited to the demands of mining operations, offering inherent strength combined with the reduced weight and flexibility needed for transport to and installation in remote mining environments.

Polypipe offers a number of product solutions for water management in mining applications such as dewatering, storage and distribution. These include PE100 pressure pipes, HDPE twin-wall gravity systems – Ridgidrain and RidgistormXL – for infrastructure and site drainage, along with Polystorm cell units for water attenuation and re-use. Polypipe delivers quality, modern, lightweight systems, which are cost effective and easier to install than traditional pipe systems.

Metso Minerals

When publishing an article about Metso Minerals slurry pump portfolio, the magazine ‘Pump Engineer’ wrote; “The solutions provider who tries harder”

A large part of Metso’s effort in providing solutions is the ‘in-house’ development of the PumpdimTM selection programme, one of the most advanced pump sizing tools available today for accurate slurry pump selection.

In order to ensure safe and reliable operation with maximum time between failure, all Metso slurry pump selections are made using PumpdimTM which not only selects the right pump for the job, it also considers all mechanical and hydraulic limitations of both pump and any pipe system.

Pipe systems, drive and pump selections are all optimized to ensure maximum efficiency and long term reliable operation in service.

Each duty is classified in accordance with ANSI/HI standard for slurry pumps, limiting maximum head and peripheral impeller speed for each of four different application classes.

PumpdimTM also makes appropriate allowances for effects of solids on head, efficiency and flow as appropriate, and in so doing, checks radial load, axial load, belt load, shaft deflection, wet end bearing life, dry end bearing life and any shaft seal limitations/requirements.

In production, all bearing cartridges are assembled and tested prior to installation in the relevant pump bearing frame. Every pump then undergoes various workshop tests including a full pressure test, and where specified witnessed test in line with ISO9906 (replacing DIN 1944). This standard resolves all ambiguities by describing in detail the requirements regarding pump test arrangements and the quality/accuracy of the instruments used, and the subsequent results.

Skilled service engineers are available for onsite commissioning in order to ensure correctness of both pump and system before equipment is put into service. Detailed check lists cover all aspects of the installation including free and correct rotation of all machines, drive alignment, vibration, noise, power consumption, pipe work and supports, seal water supply (where required), lubrication, safety guards and on site knowledge of the equipment use and maintenance.

Gardner Denver Nash

Founded in 1905 as Nash Engineering, Gardner Denver Nash was created in September 2004, when Gardner Denver acquired Nash_Elmo Industries from Audax.  Nash_Elmo resulted from the 2002 merger of The Nash Engineering Company, USA, and Elmo vacuum technology GmbH, Germany, formerly a Siemens subsidiary.  The combining of Nash, the leader in liquid ring vacuum pumps, with Elmo, the leader in side channel blowers, created Nash_Elmo, a global leader in vacuum technology.

According to Gardner Denver Nash Marketing Manager, Amy Harold, their company has a manufacturing plant in South Africa. Amy also added that their products can be ordered directly from them or purchased through their designated agents across Africa.

Their NASH TC/TCM liquid ring vacuum pumps are highly reliable and efficient. These pumps, with their integral two stage impeller, are able to condense process vapors and to recover or dispose of the vapors. Another benefit of these pumps is that they can attain vacuum levels down to 0.8″ HgA (20mmHgA). This is approximately 40 percent lower absolute pressure than a single stage pump.

The NASH TC and TCM models are designed to handle large amounts of liquid carryover without difficulty. This ensures reliability under the most demanding applications.

The Nash Division of Gardner Denver has manufacturing facilities in South Africa, China, Germany and Brazil and Engineered to Order (ETO) centers in Bentleyville, Pennsylvania, USA; Singapore; Smithfield, NSW, Australia; Nuremberg, Germany and Assendelft, Netherlands.  Their service centers are ISO 9001:2008 certified and can be found in North America; England, Germany, Sweden and the Netherlands; Australia, Singapore, Korea, Brazil, and South Africa.

KETO Pumps

KETO Pumps is a designer, manufacturer and supplier of slurry pumps, solutions and associated products. Their presence in Africa has been strengthened with their recent acquisition of Benex Mining Services (Rustenburg, North West Province), AGM Pumping (Middleburg, Mpumalanga) and Pump Services Botswana (Selebi-Phikwe, East Botswana). KETO’s African product range has also expanded.

They realize the commodity prices for gold, platinum and other materials are putting pressure on many African mines to become more efficient. KETO upgrades (including K-ISS™ mechanical seals, K-HEE™ impellers and K-IBA™ bearing assemblies) significantly enhance wear life and will reduce parts operating expenses as well as energy and water usage.

KETO Keramithane™ is a new technology which was developed in their Richard’s Bay facility. Keramithane™ is a cost effective and high wear material which combines the advantages of ceramic and urethane for slurry pump wear parts. The result is extended wear life of slurry pump wear parts for a wide range of round edge solids, as compared to conventional urethanes.

Chris Neil , General Manager African Operations says “When selecting pumps provide as much information about the system conditions in which your pump is operating and also as much about the fluid you are pumping. A pump manufacturer can then take this information and marry this to the most efficient solution from their range in terms of hydraulics and materials used. If you’re replacing parts or complete pumps in a system then also consider getting the representatives of a pump company out to site to discuss the application this is particularly important for pumps that are considered “bad actors” or are consuming parts at a rapid rate. Often after reviewing site conditions or viewing worn parts a better solution than a simple replacement can be offered, possibly involving basic improvements to piping arrangements, valves or upgrades to the pump itself. A lot can be diagnosed from this type of analysis that could lead to big savings in the long run”.

BBA Pumps BV

For more than 60 years BBA Pumps has been an advanced and innovative manufacturer of mobile pump systems for various markets, including the rental and well-point drainage markets and civil works. Their pump solutions are a guarantee for quality, sustainability and maximum performance at minimal costs.

Minetuff Pumps Australia

Minetuff Pumps Australia opened its doors in early 2009, to service a niche industry that demands a reliable piece of pumping equipment for the brutal task of underground mine dewatering. The environment that Minetuff pumps typically find themselves could be rephrased as ‘mine de-muddering’ rather than dewatering. Although true that water is one of the problems that Minetuff pumps is asked to cope with, add to this the prevalence and challenge of sharp edged stones, fines, shotcrete & hyper saline water, to name but a few issues, and you find that mining needs a liable piece of machinery to keep the flow moving. Minetuff Pumps have stepped up to the task and have used their vast mining experience to incorporate this request into their product. From stainless steel housings on the mechanical seals, to stainless steel impellers and polyurethane linings on the wet end components and you have a tough pump for a reasonable price-tag.

Other components have been manufactured from bronze and stainless steel for hyper saline environments when sacrificial zinc anodes are simply not enough. Minetuff Pumps cables are side entry and have the option of cable protection kits which further reduces the risk of cable damage. Add to this the cleverly designed reinforced carry handle and you have a ‘Tuff’ little package. Currently, Minetuff Pumps range in size from 5kW to 37kW and most components are interchangeable with other well-known industry pump brands.

Every minute of downtime that a pump accounts for means lost mining time which equates to lost money. A mine dewatering pump needs to be reliable to keep the water level down and the mine operational, and what better way to have peace of mind than knowing that you have a liable piece of machinery like a Minetuff pump operating down in the dark unsupervised.

Steven Ward from Minetuff Pumps Australia advises mining pump potential buyers to investigate the technical aspect and spare part back up your supplier can give your project.

According to their slogan “in the region for the region” they have over 30 sales offices and more than 200 NETZSCH representatives close to you wherever you are.

NEMO® progressing cavity pumps from NETZSCH pumps and systems are increasingly used to save on maintenance and process costs, as they are capable of withstanding problematic abrasive or chemically aggressive media thanks to smooth pumping technology and exceptionally robust components.

Even the high abrasiveness of gold sludgedoes not create problems. The precious metal can then be separated from the crushed material matrix using a variety of different methods, including cyanide leaching and amalgamation with mercury. The stone particles in the sludge behave like sandpaper, particularly at high speeds, and wear away all surfaces extremely quickly. This effect can only be reduced by particularly smooth pumping at an economically viable volume, as further tests with a NEMO® progressing cavity pump demonstrated.
