This white paper shows the comparison of operational costs and net present value (NPV) of project investment between thickened tailings disposal and conventional lean tailings disposal.
Weir Minerals is a global leader in delivering high-quality engineered products for slurry transportation, comminution and minerals processing applications in the mining and construction aggregates sector.
With over 140 years of experience, the company’s solutions aim to enhance productivity, operation longevity, capacity and efficiency by combining a hydraulic design and corrosion-resistant materials.
Piston diaphragm pumps for handling abrasive materials
The GEHO® TZPM pump is a crankshaft-driven piston diaphragm pump, which is designed to handle coarse mineral ores, minewater and tailings slurries.
Designed for pumping solids and liquid mixtures, as well as high-pressures or hydraulic heads, the unique GEHO® diaphragm protects pistons and liners from abrasive slurry contact.
The heavy-duty GEHO® TZPM pump offers low operating costs, energy consumption levels and a reduced carbon footprint, as well as long maintenance intervals and high-mean time between failures (MTBF).
The pump is suitable for a wide range of applications, including mine backfill, dewatering, coal slurry transport and gasifier feed, as well as hydraulic ore hoisting. In addition, further applications of the pump are in autoclaves, digesters and reactor feeds.
Other pump uses are in pipeline transportation, sludge transfer, tailings disposal, high-concentration slurry disposal (HCSD) ash disposal, and thickened sludge processing.
Pumps for processing dense abrasive slurries
The Warman® MCR pump is designed to handle large particles in thick abrasive slurries and offers highly efficient large-diameter, low-speed impellers. It is suitable for mill discharge and slurry transportation applications.
Featuring interchangeable elastomers, metal liners, or unlined metal, the Warman® MCR pump incorporates state-of-the-art wear-resistant materials, a self-centring stuffing box design, and an easy ‘full face’ side liner adjustment.
A fast ‘one-piece’ wet-end change-out version is available for larger pump sizes.
Linatex® Premium rubber sheet
For more than 90 years, Linatex® rubber has been providing superior protection for mining, sand and aggregates equipment.
Linatex® rubber products are strong, tough and resilient. Combined with the excellent tear, cut and abrasion-resistance, Linatex® premium rubber is irreplaceable in abrasion trouble spots.
Made using a patented technique that retains the attributes of natural latex, our durable rubber products are ideally suited for the lining of hose, chutes, valves, screen equipment, cyclones and pumps in adverse mining conditions.
Custom-built dewatering pumps
The Multiflo® diesel-driven, vacuum-primed units pump water against high head situations, slurries and solids from open-pits, making them suitable for dewatering operations at mine sites.
Fully customisable to meet specific demands, the Multiflo® range incorporates an array of corrosion and wear-resilient materials to pump corrosive minewater, while an extensive combination of engines and wet-ends offer optimal performance.
Multiflo® units can be customised to include options such as auto start / stop functions, discharge and suction arrangements, as well as monitoring instrumentation.
About Weir Minerals Solutions
Weir Minerals has a powerful team of experienced and qualified process engineers and service technicians to support their customers, backed with a network of service centres spanning 120 countries worldwide.
Weir Minerals’ solutions experts take the time to understand customers’ entire process, analyse any problems and bottlenecks, as well as propose ways to improve and optimise systems.
Incorporating Weir Minerals engineering and process expertise, along with its market-leading equipment, the company’s solutions experts help customers achieve increased throughput with reduced downtime.
A simple slurry wear type (SWT) number based on particle size and size distribution is proposed as a means for categorising slurry pump wear patterns and optimising pump application and material selection.
Weir Minerals announced the expansion of its extensive dewatering solutions portfolio with the global launch of the Multiflo® RF dewatering pump unit.
Weir Minerals has announced the global launch of the second-generation Warman® WGR® pump for the sand and aggregate market.
Weir Minerals announce their long-term strategic cooperation agreement with International technology group ANDRITZ to supply equipment for processing tailings in the mining industry.
Weir Minerals has announced an upgrade to its polymer-ceramic composite for the Flue Gas Desulphurisation (FGD) market. Specially engineered for use in FGD applications, the new and improved Cerasmooth™ compound is designed to provide ultimate wear and corrosion resistance.
The Warman® Design and Build Competition, established by Engineers Australia and sponsored by Weir Minerals, has been providing first and second year Mechanical Engineering University students in the Asia-Pacific the opportunity to apply their knowledge in a practical application for 30 years.
With changing market conditions and improvement expected over the next two years, Weir Minerals is positioning itself even closer to its customers. The company has announced its ambitious growth plans, building upon its leading 130 service centres strategically positioned across the globe.
Crushers operate at high power, force and capacity in order to produce the required materials. This puts a great deal of strain on the crusher and its wear parts, which operators must be aware of when carrying out maintenance. Failure to do so may have a high impact, both in terms of financial cost and potential loss of production.
As merger and acquisitions opportunities and greenfield projects diminish, there is a strong focus on modifying and optimising existing mine sites and processes to achieve greater operational efficiency.
