Answer:
Roasting- During this process, extraction is done by heating the ore in a regular supply of air. Sulphide ores of elements such as Zinc, Lead and Copper are treated and concentrated using this methodology. The sulphur in the ore, at high temperature reacts with the oxygen to form Sulphur Dioxide and escapes out.
