The QP preparing the mineral resource estimate should seek the advice of a mineral processing specialist after these initial estimation stages. As the deposit evaluation progresses and the
The Four Types of Mineral Processing
However, the article then states that leaching is not classified as a mineral processing method, but instead should belong under the umbrella of hydrometallurgy. Much like dewatering, leaching is frequently necessary within mineral processing plants, so if dewatering is a type of mineral processing, leaching falls in line for similar reasons.
Mineral Processing
Haldar described mineral processing «as the value-added processing of raw material (run-of-mine ore) to yield marketable intermediate products (e.g. copper concentrate) or finished products (e.g. silica sand) containing more than one valuable minerals and separation of gangue (tailing).»The run-of-mine components consist of the following: 1. ...
