In secondary lead production, the alloying elements (in recycled acid/lead batteries) are removed by refining processes. The presence of arsenic, tin, and antimony causes hardness in lead, which is otherwise soft in its solid state. Softening process is used to remove arsenic, tin, and antimony from lead bullion.
The choice and justification of the pyrometallurgical technology primarily depend on the antimony content in the initial concentrate. Gold is considered a byproduct in the antimony refining process [3,4]. The presence of even small concentrations of antimony in gold-containing ores has a detrimental effect on the process of gold …

Refining and fine purification techniques are used for production of pure antimony metal. There is growing demand for extremely pure antimony. Antimony oxide is being used as flame retardant in increasing quantities. Antimony is a component of many lead and tin alloys, which are important materials for making bearings and solders.
The traditional method of producing antimony metal is through heat smelting. However, researchers at MIT claim to have accidentally stumbled upon a new method of smelting using electrolysis rather than heat. Research was funded by the US Department of Energy, the Advanced Research … See more
A major challenge in the smelting and refining of copper (Cu) is the control of the concentration levels of metal impurities that are deleterious to the final copper product.
