Magnetic separation is the process of using magnetic force to remove metallic or ferrous materials from a mixture. Magnetic separation machines consist of a vibratory feeding mechanism, an upper and lower belt and a magnet. The bulk material is fed through the vibrating mechanism onto the lower belt. At this point, the magnet pulls …

The dry magnetic separator is used for sorting dry magnetic minerals, and is mainly used for selecting large-sized, coarse-grained ferromagnetic ores and fine-grained weak magnetic ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m.

Solvent extraction is another alternative technique to extract gold from leachate. It is scalable for the selective separation of a particular metal, in this case gold, from a mixed-metal feedstock (Raiguel et al., 2020). Metals are extracted using solid/liquid extractants or chelating agents accoupled with inert solvents.

Before the flotation separation, it can also be used for processing the nonferrous ores. The FTM Machinery Shaking Table can be used for roughing, concentration, and sweeping to separate coarse sand (2–0.5 mm), fine sand (0.5–0.074 mm), sludge (within 0.074 mm), and other different particle sizes. It is very effective for selecting fine ...

As you will see if you read the page about titanium extraction, this is the only way of producing high purity metal. TiCl4 + 4Na → Ti + 4NaCl T i C l 4 + 4 N a → T i + 4 N a C l. The more reactive metal sodium releases electrons easily as it forms its ions: 4Na → 4Na+ + 4e− 4 N a → 4 N a + + 4 e −. These electrons are used to reduce ...

Therefore, DMS methods are widely used in the separation of coal and various metal ores and non-metallic ores. Direct separate clean coal and waste rock; separate coarse waste tailings and rough concentrate. For the ordinary gravity separation method, the lower limit of the feeding ore is about 2-3mm (the coal is 3-6mm).
