Roasting in Metallurgy - Mineral Processing

In metallurgy, the operation of roasting, as a preliminary to chlorination, has for its object the expulsion of the sulphur, arsenic, antimony and other volatile substances existing in the ore, and the oxidation of the metals left behind, so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in aqueous solution. For this purpose the ore is heated in a

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

Smelting and Roasting Ores to recover gold, silver

Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur dioxide, which is a gas and is emitted to the air. The process works best when the ore is crushed to small pieces before roasting.

Antimony Ore - Cargo Handbook - the world's

The industrial methods to produce antimony are roasting and subsequent carbothermal reduction or direct reduction of stibnite with iron. The extraction of antimony from ores depends on the quality of the ore 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
