Ores and Minerals - Introduction, Extraction ...

Minerals are naturally occurring, homogeneous inorganic solid substances having a definite chemical composition and characteristic crystalline structure, color and hardness. For example, copper pyrite (CuFeS 2), calamine (ZnCO 3) etc. are minerals. A mineral from which metal can be economically extracted in a maximum amount is called an ore.

Underground extraction. In underground mines the ore is accessed by driving ramps or shafts down to the level where the ore is extracted. Many underground mines lack ramps, and people and machines must be transported in shafts. At the extraction levels, production areas are prepared, i.e. drifts (tunnels) are driven to the ore face.
