Gold Extraction from Different Types of Ore

Gold Extraction from Different Types of Ore

Jan 10, 2020 Antimony-bearing sulfide gold ore refers to the antimony-bearing sulfide or gold ore in which antimony minerals exist independently. This type of ore is generally difficult to be extracted by amalgamation and cyanidation directly, so flotation, roasting, and cyanidation gold extraction processes are often used to extract this type of gold.

Antimony Recovery from End of Life Products and Industrial

Feb 08, 2016 Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and …
