How Antimony is Processed by Flotation

The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount of talc.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore..

Antimony - Wikipedia

Production process. The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals.

Gold parting - Wikipedia

Gold parting as a process was specifically invented to remove the silver. The main ancient process of gold parting was by salt cementation and there is archaeological evidence of that process from the 6th century BC in Sardis, Lydia. In the post-medieval period parting using antimony, sulfates and mineral acids was also used.
