18-03-2016  Hence the percentage of extraction is 73.5 per cent.; i.e., the loss amounts to 7 per cent., taking the trioxide as containing 80.5 per cent. Sb. Summing up, we have a loss of about 19 per cent, of antimony from ore to regulus. The consumption of coal is 0.55 ton per ton of regulus, and the average life of the hearth bottom is 12 weeks.

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.

Refractory Gold Ore Treatment Methods

It is generally known that antimony can be readily volatilized, and by roasting stibnite (Sb2S2) in an oxidizing atmosphere, antimony oxide can be driven off and condensed. At the same time, anyone who has had experience with such roasting knows that it is a delicate process. To begin with it is impossible to drive off the antimony completely.
