Mineral concentrate becomes pure quality metals
In our smelters we refine mineral concentrates from our own and other mines into pure metals. We are also the market leader in electronics recycling and lead recovery from car batteries. Constant streamlining and stable processes allow us to maximize the production of both metals and by-products in a strategy that provides a broader product range, lower residual waste in production and increased competitiveness. We also focus on safeguarding and developing our corporate responsibility in terms of health, safety and the environment at every level.
Metal production – how it works
We mine complex ores, i.e. ores that contain several different metals The metals and other by-products are separated in smelting plants in a variety of different processes including smelting, calcination, leaching, purification and electrolysis before being cast as pure metals.
Our smelters produce mainly zinc ingots, copper cathodes, lead ingots, gold and silver granules and other products such as sulphuric acid, zinc clinker, sulphur dioxide and palladium concentrate.
