Antimony Wikipedia

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 Extraction from Different Types of Ore

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.
