Base Minerals and Mining

Secure separation for high-grade concentrates and safe disposal of tailings

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 has a broad range of energy efficient, compact, easy to maintain heat exchangers for heating and cooling in various mineral processing applications. There’s a vast range of options in term of size, plate and gasket material. Our solid-bowl decanter 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.

Tackling tailings safely and sustainably

Alfa Laval decanter centrifuges are a proven, efficient solution for large-scale dewatering of tailings and removing the finest particles that conventional solids control equipment is unable to deal with. They offer a cost effective, sustainable and, above all, safe solution to manage tailings, acting as a complement to traditional separation systems such as thickeners, sedimentation basins and filters or replacing old systems altogether.

How it works

Alfa Laval’s solid bowl decanter centrifuges have been specifically developed for large scale, heavy duty solid-liquid separation tasks in the mining and mineral industry.

A Solid Bowl Centrifuge (SBC) consists of a horizontal bowl with a scroll conveyor inside it which is together referred to as the rotating assembly. The assembly spins around its own axis at high speed, thereby generating high centrifugal force that enables separation of tailings solids from the liquid. The separated solids are scrolled out by the conveyor in the form of a dry solids cake whereas the clear liquid (centrate) overflows the weir plates located at the opposite end. Watch the animation to see how it works.

Process mining

On the pulse of mineral processing

Alfa Laval help alumina, 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.

Big energy savings through heat transfer

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.

Optimizing separation efficiency

Whether used for solvent extraction, electrowinning, dewatering, recovery of intermediate products, or separation processes, Alfa Laval centrifugal separators are reliable, resilient and equipped to deal with the complex solid-liquid or solid-liquid-liquid separation involved in mineral processing.

Due to highly efficient operation, robust design and the resulting high purity output, Alfa Laval separation solutions are an integral part of nearly all processes in the recovery of mineral raw materials. Which is why metal producers the world over rely on Alfa Laval to help maximize productivity and increase yields.
