Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the

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

The separation of mineral from gangue is known as mineral processing, mineral

Ore Sorting Strategies In Mineral Processing

Benefits Of Dense Medium Separation. While dense medium separation can only rely on density to distinguish valuable materials from waste, it has the advantage of being able to sort a wider range of particle sizes. With ore sorting, the largest particle size should be no more than 3 times that of the smallest particle.

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.
