Base Minerals and Mining

Optimise your mining processes to reduce operational cost and improve sustainability

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 its operations, reduce cost 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 eliminating tailings dams, minimise environmental impact and enhance the intrinsic safety of your operation. Alfa Laval's broad range of energy efficient, compact, easy to maintain 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.

Solid bowl centrifuges

How it works

Alfa Laval P2 and P3 solid bowl decanter centrifuges are specifically designed to separate mining and mineral slurries, tailings and sludge into a solid phase and liquid phases.

Separation takes place in a horizontal cylindrical bowl equipped with a scroll conveyor. The product is led into the bowl through a stationary inlet tube and is then smoothly accelerated in a full-flow feed zone design. Centrifugal forces of up to 3,500 G make the solids accumulate on the inner surface of the bowl.

The conveyor rotates in the same direction as the bowl, but at a different speed. This moves the solids towards the conical end of the bowl. The solids leave the bowl through the solids discharge openings into the casing.

Separation takes place throughout the length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over adjustable plate dams into the casing.

Heat exchangers

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 many megawatts of hidden energy each year.

Gasketed plate-and-frame heat exchangers

Gasketed plate-and-frame heat exchangers provide efficient heat transfer in compact equipment with a small footprint. The units have a flexible design and are easy to service and maintain. Recover more heat and reduce energy consumption and carbon footprint.
