- Contained process promotes good and safe working conditions
- Water re-use helps boost operational sustainability
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.
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.
