Mining & Minerals

Africa’s mining and minerals sector requires high-performance industrial valves for mineral extraction, ore processing, slurry handling, tailings, dewatering, concentrate transport and water-treatment facilities. African Valve provides valve solutions for abrasive, corrosive and high-solids services, selected according to slurry characteristics, pressure, temperature, particle size and project requirements. 

Mining & Minerals Valve Solutions 

African Valve supplies industrial valves for demanding mining applications, including Knife Gate Valves, Slurry Valves, Pinch Valves, Ball Valves, Butterfly Valves, Gate Valves, Globe Valves, Check Valves, Plug Valves and Actuated Valves. These valves support slurry isolation, abrasive media handling, process-water control, tailings pipelines, concentrate lines, pumping systems and mineral-processing equipment. Knife gate, pinch and slurry valves are commonly selected for high-solids and abrasive services, while ball, butterfly and gate valves provide isolation across process and utility systems. 

Mining & Mineral Processing 

For African mining operations, valves are used in crushing and screening plants, grinding circuits, hydro cyclones, flotation systems, thickener underflow, filtration, concentrate handling and slurry pipelines. Severe slurry applications may require abrasion-resistant construction, hardened components, reinforced seats and specialised pressure ratings. Mining operations across South Africa, Zambia, Democratic Republic of Congo, Zimbabwe, Botswana, Namibia, Ghana, Mali, Guinea, Tanzania, Morocco, Mauritania and Sierra Leone require valve solutions adapted to abrasive ores, corrosive process fluids, high solids concentration and demanding operating environments. 

Slurry, Tailings & Dewatering 

Slurry and tailings systems require reliable valves for mine slurry pipelines, tailings discharge, thickener systems, dewatering lines and pumping stations. Valve selection considers solids concentration, particle size, velocity, pressure and wear rate. Pinch and knife gate configurations can provide effective isolation in heavy-duty slurry applications. 

Water & Process Applications 

Valves are used for process water, cooling water, mine dewatering, wastewater, reagent dosing and water-treatment systems. Butterfly, ball, gate and check valves can be selected according to line size, pressure and fluid characteristics, with corrosion-resistant materials available for chemically treated or contaminated water. 

Materials & Technical Construction 

Actuation & Automation 

Valves can be supplied with pneumatic, electric or hydraulic actuators for remote isolation, automated process control and plant safety systems. Actuation packages may incorporate solenoid valves, limit switches, position indicators, positioners, gear operators and fail-safe arrangements. 

Applicable Standards 

Depending on valve type and application, mining projects may specify API 598, ASME B16.34, EN 593, EN 1983, ISO 5752 and applicable project-specific requirements. Valve testing may include shell testing, seat testing, hydrostatic testing, pneumatic testing and functional testing.
