Flotation: Flotation is based on the difference in physical and chemical properties of the mineral surface, and through flotation agent treatment, the minerals are selectively attached to bubbles to achieve the purpose of sorting. Flotation is mainly used to process non-ferrous metal ores, such as copper, lead, zinc, etc., and is also suitable for some ferrous metals and non-metallic ores.
Magnetic separation: Magnetic separation is based on the difference in magnetic properties of minerals. It is mainly used for ferrous metal ores (such as iron, manganese, chromium), and is also used for the sorting of non-ferrous and rare metal ores. The magnetic separator separates minerals of different magnetic properties through the action of the magnetic field.
Electrostatic separation: Electrostatic separation is a separation method based on the difference in conductivity of minerals. When minerals pass through the high-voltage electric field of the electrostatic separator, they are subjected to different electrostatic forces due to their different conductivity, thus achieving separation. Electrostatic separation is suitable for the separation and selection of rare metals, non-ferrous metals and non-metallic ores.
Bacterial separation: Bacterial separation uses microorganisms (such as iron-oxidizing bacteria and sulfur-oxidizing bacteria) to oxidize or decompose specific components in minerals for desulfurization, deironization and desiliconization. In addition, bacterial separation can also be used to recover metals such as copper and uranium.
