The process of procuring metals from ores is called metallurgy and these naturally occurring compounds of metals are known as minerals. Metals are usually extracted from the earth by mining. Ores. All ores are minerals, but not all minerals are ores. Ores are those minerals which contain metals. The picture shown above is a goldbearing ore.

Roasting (metallurgy)

Roasting (metallurgy)

Roasting is a process of heating of sulphide 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 gassolid 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.

What are Ores and Minerals? Most metals are too reactive to exist on their own in the ground. Instead, they exist combined with other elements as compounds called ores. Ores are raw materials for making metals. Minerals are those in which individual crystals are composed of unit cells or basic unit layers of two or more types.
