antimony refineing process

Antimony process - American, Smelting Refining. The process for treating copper-bearing antimonial lead which comprises concentrating the antimony in a dross containing 70% to 80% antimony, volatilizing antimony oxide from said dross, recycling the residual metal until the copper content exceeds approximately 8% and then cooling the residual metal sufficiently to

Zone Refining

Zone refining is a very useful method to get metals with very high purity such as silicon and germanium. It is also referred to as zone melting, floating zone process, and travelling melting zone. What is Zone Refining? Zone refining refers to the method of purifying a crystal wherein a thin region of the crystal undergoes melting.

Specialty Metals and Minerals

Antimony, along with rare earths and tungsten, is a strategic metal for China and is therefore subject to export quota (read more about strategic minerals/metals here). This, along with mine closures for environmental and depletion reasons, and forced smelter consolidations, has significantly tightened supply since 2007.
