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.

Heavy Mineral Analysis - Technique - Heavy mineral

The separation is done in a separating funnel in a temperature controlled room of 20°C. The “heavy” grains will accumulate in the bottom of the funnel above the pinch clip and the “lighter” grains float to the surface. After 6 – 8 hours of separation the pinch clip is opened and the heavy minerals are drained onto a

Magnetic Separation Method - Mineral Processing

2015-6-24  Magnetic separation has two major applications in mineral processing plants: The removal of tramp iron (which would deleteriously affect subsequent processes) from an ore stream. This is usually achieved by a low intensity magnet suspended above, or at the head of, a conveyor. Separation of magnetic minerals from less magnetic minerals.

Magnetic Seperation

2002-2-13  Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will stick to the poles of the magnet. These minerals can be separated by wrapping the poles of a magnet in paper, passing the magnet over the mineral
