Antimony Sulfide Refining

The first step is mineral processing which consists of ore crushing and dressing. The second step is called process metallurgy or extractive metallurgy in which the resulting minerals are reduced and refined to produce the pure metals.

Silver Refining and Recovery emewCorporation

Lead sulfide concentrates are roasted and smelted to form lead bullion. The various impurities including antimony, arsenic, silver, and tin are removed by various different processes silver is removed by the Parkes process. In this method of liquid-liquid solvent extraction, zinc is added to a molten leadsilver mixture and cooled slowly.
