Base Minerals and Mining
Alfa Laval has a range of equipment and the knowhow to help you optimise key processes in base mineral beneficiation and extraction applications. Our aim is to help you boost capacity, save space, raise yields and ensure operational safety. Applications covered include heating, cooling, heat recovery and condensation as well as concentrate and tailings dewatering and intake water treatment by evaporation.
Highly robust equipment with minimal operator intervention
- Proven short payback time
- High volume capacities and space-saving equipment designs
- Maximise recovery of valuable products and minimize waste
- Contained process promotes good and safe working conditions
- Water re-use helps boost operational sustainability
Alfa Laval helps mining businesses improve operations, reduce costs and gain environmental benefits leveraging its leading technologies for solid liquid separation and heat transfer. Our solid bowl centrifuges can replace or complement existing installations such as thickeners, filters and sedimentation basins. They help reduce operating costs and, by reducing reliance on tailings dams, minimising environmental impact and enhancing the intrinsic safety of your operation. Decanter centrifuges are also essential during exploration drilling. Alfa Laval's broad range of energy efficient, compact, easy to maintain industrial heat exchangers are engineered for heating and cooling in various mineral processing applications. There’s a vast range of options in term of size, plate and gasket material to maximise heat recovery and reduce energy consumption.
On the pulse of mineral processing
Alfa Laval help alumina, iron ore, copper, zinc and nickel producers get the most out of raw ores – cost-effectively, energy-efficiently and in an environmentally friendly way. From smart reuse of process waters and recirculation of cooling waters to treatment of bleed streams and smart solid waste reduction, count on Alfa Laval.
Smart reuse of the vast amounts of heat involved in these processes can contribute directly to the bottom line. While dewatering and separation technologies help extract valuable by-products, reduce waste streams, and minimize environmental impact. Alfa Laval has the process know-how as well as a broad portfolio of equipment and services to help metal producers cut costs, achieve significant energy savings and raise yields.
Heat exchanger technology maximises heat recovery and energy savings
Beneficiation, digestion, roasting, leaching, smelting and electro-winning are all energy-intensive processes. By harnessing the heat generated during extraction processes and reusing it in other processes, metal producers not only save big on energy costs, but also boost productivity.
Our heat exchangers (gasketed, welded or spiral) are a proven and highly efficient technology for heat transfer to feed the heat back into the process with unparalleled yield. The heat exchangers’ close temperature approach, high internal turbulence and large heat-transfer areas combine to squeeze out up to 30% more energy than conventional shell-and-tube units out of every heat flow. By replacing costly and bulky units with Alfa Laval heat exchangers, processing plants can save cost and recover many megawatts of energy each year.
Optimizing separation efficiency
Whether used for solvent extraction, electrowinning, dewatering, recovery of intermediate products, or separation processes, Alfa Laval decanter and separators are reliable, resilient and equipped to deal with the complex solid-liquid or solid-liquid-liquid separation processes involved in mining production.
Due to highly efficient operation, robust design and the resulting high purity output, Alfa Laval solid bowl decanter centrifuges are an integral part of nearly all processes in the recovery of mineral raw materials.
Used in tailings applications, mining companies see a reduction in water usage by up to 90%, as they are able to extract and re-use the process water. They are also able to dispose of the dry tailings in a similar fashion to overburden and together with coarse rejects.
