25.4 Separating minerals from waste Mining of mineral ...

A number of different separation techniques are used. These techniques are based on the properties of the minerals. Different minerals are often found together, for example copper and zinc, gold and silver or the PGMs. A combination of techniques are used to separate the minerals from the waste and then the minerals from each other.

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. These functions are carried ...

For a successful separation by RGB cameras, the colour of the valuable minerals and the waste rock fraction must differ significantly. If both fractions show a similar colour, the application of NIR-process technology will enable a successful separation nevertheless. Each NIR active mineral shows a unique pattern in the NIR spectrum.

of the minerals, the caustic soda method has gradually taken its place. The acid method is to the process used for Bastnäesite at e.g. Bayan Obo (see below). • The caustic soda method begins with dissolving the mineral in concentrated sodium hydroxide at 140 – 150 °C, which turns REE and thorium into hydroxides.
