6. Mineral Extraction from Ores If there is a large enough amount present, the rock will be extracted and processed in a variety of ways (depending on the type of mineral) to remove the mineral from the surrounding rock. Generally, the ore and the gangue are mined together—i.e., taken out of the host rock in a mass by either mechanical or manual means.
