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.
On the pulse of zinc processing
From roasting, sintering, casting to leaching, purifying, electrowinning, melting and casting, reducing zinc sulfide concentrates to metallic zinc requires expertise. 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 zinc producers cut costs and raise yields.
Big energy savings through heat transfer
Energy efficiency makes a major contribution to zinc processing profitability. By ensuring maximum heat transfer efficiency throughout all processes, zinc producers not only save big on energy costs, but also boost productivity.
Introducing Alfa Laval spiral heat exchangers to acid leaching processes, for instance, enables the smart reuse of heat from rich acid to pre-heat the lean acid in solvent extraction process streams.
Our gasketed heat exchangers capture the heat from spent electrolyte and use it to preheat strong electrolyte prior to electrowinning. The gaskets are designed with aggressive environments in mind, ensuring leakage-free performance and long service lifetimes.
With smart, low-maintenance, space-saving designs, all Alfa Laval heat exchangers promote high turbulence and velocity control, minimizing the need for cleaning and maximizing energy savings.
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. separation processes involved in zinc production.
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 zink producers the world over rely on Alfa Laval to help maximize productivity and increase yields.
