What's your treasure?
Alfa Laval offers robust decanter centrifuges as well as gasketed, welded and spiral heat exchangers, each optimized for specific duties and operating conditions in mineral processing. Find out more by downloading the brochure.
The extraction of alumina involves energy-intensive processes, such as digestion, evaporation and liquor heating. The challenge? How best to recover and reuse process waste heat to reduce costs and raise yields. To succeed, aluminium manufacturers require process know-how as well as highly reliable equipment and smart services that optimize performance, ensure uptime and increase profitability.
To get the most out of energy-intensive copper processes – from leaching to electrowinning, copper producers reuse excess heat in the same process stream and improve solid-liquid separation duties with more efficient, space-saving decanter centrifuges. Alfa Laval’s know-how, equipment and services help recover water, energy, chemicals, and minerals thereby increasing productivity.
Limited supply, fluctuating prices and rising costs pose challenges for the global zinc producers. Yet demand for zinc remains steadfast for steel galvanization, brass production, coatings for other metals, paints and primers as well as a variety of new applications. Successful production requires reliable, low-maintenance, resource-efficient equipment that minimizes costs and maximizes yield.
Nickel producers face many challenges – from reducing energy, chemicals and environmental costs. Getting the most out of lateritic or sulfidic ores requires a trustworthy partner. Alfa Laval’s vast expertise with nickel refining processes and a broad equipment and services portfolio helps reduce costs and environmental impact, recover valuable minerals and by-products, and increase yields.
Uranium production requires a deep understanding of how to best process varying ore compositions and cutting-edge technologies that reduce the use of energy, water and chemicals. From heating and cooling, leaching and thickening to solvent extraction, precipitation and enrichment, uranium producers count on Alfa Laval for heat transfer, separation and fluids handling equipment that optimize processes and boost yields.
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.
