Automation and Robotics in Mining and Mineral Processing
The aim of a mineral processing operation is to concentrate a raw ore for the subsequent mineral extraction stage. Usually, the valuable minerals are first liberated from the ore matrix by comminution and size separation processes (crushing, grinding, and size classification) and then separated from the gangue using processes capable of …

Introduction to Mineral Processing
In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.
