what is roasting in mining

The most important operations are roasting, smelting, and refining. Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas. Smelting (q.v.) is the process used in blast furnaces to reduce iron ores. Tin, copper, and lead ores are also smelted

Roasting This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine. Smelting with fluxes A flux is a substance which is added to the ore to make it melt more easily. The solid calcine is heated to 1200°C and melts
