Quizplus · Accepted Answer

Roasting is a thermal process where the ore is subjected to high temperatures in the presence of air or oxygen. This causes reactions between the ore and the atmosphere of the furnace. The aim of roasting is to convert the ore into an oxide, which can then be reduced to extract the metal. Smelting involves the reduction of the metal oxide to the metal itself, while calcining is a heating process used to remove volatile components from a material. Refining is the process of purifying metals after they have been extracted. Slag is the byproduct of smelting or refining processes.
