The Irish Metals process has incorporated the secondary treatment and produces a marketable antimony product. The process uses minimal water and significantly reduced quantities of reagents. In addition to antimony, the process can recover value-added metals to include silver, copper, cobalt, nickel, zinc, and manganese.

Our process | Umicore Precious Metals Refining

The main processing steps of the Base Metals Operations are the blast furnace, the lead refinery and the special metals plant. The blast furnace reduces the oxidized lead slag from the smelter together with high lead containing third party raw materials and transforms them into impure lead bullion, nickel speiss, copper matte and depleted slag.
