Main beneficiation methods and processes?
1. Gravity separation: a method of sorting according to different mineral density. Such as: selection of tungsten, tin ore and so on.
2. Magnetic separation: a method of sorting according to the different magnetic properties of minerals.
3. Flotation: According to the wettability and different properties of the mineral surface, appropriate agents are added for sorting. Hydrophilic Minerals: Quartz, Mica, Calcite… Hydrophobic Minerals: Paraffin, Sulfur, Talc, Graphite…
4. Chemical beneficiation: Separation is carried out by using the different chemical properties of minerals. Such as gold all-slime cyanidation.
