Types of gold ore that can be treated by flotation
Gold ore has the lowest content of gold. The main feature of flotation is that a small amount of gold is floated from a large amount of pulp. When gold is recovered from gold-containing sulfide mineral particles, it is difficult to directly carry out cyanidation and gold extraction. However, the flotation method can be used as a concentrate product to recover gold. The flotation of gold-containing sulfide concentrates, which can be extracted by cyanidation, must be carried out after fine grinding. If it cannot be directly cyanated, it can be calcined or metallurgically treated.
In general, gold ore containing gold can be treated by flotation in the following cases:
1. Gold and sulphide are closely symbiotic, and gold enters the mineralized foam to produce concentrate.
2. Gold is not mostly symbiotic with sulfide minerals, but a sufficient amount of sulfide minerals in the ore ensures a stable mineralized foam containing gold sulfide ore.
3. free of sulfide mineral ores, but contains a lot of iron oxide, ocher mud contained in the ore case plays a role of the foam stabilizer;
4. sulfide mineral ore or iron oxide containing no minerals, but easy to float and capable of containing the foam stabilizing minerals (e.g., sericite, etc.);
5. Pure quartz gold ore is pre-selected with sulfide minerals, or added with sulfide minerals (about 3% (or added a suitable agent to form a stable foam.
6. After recovering the main valuable components ( copper , lead , arsenic, etc.) in the ore by flotation, the tailings can be treated by cyanidation.
we have belt conveyors consist of standard parts, which are advanced and simple in structure, easy to maintain. Our belt conveyor equipment is is widely used in different industry to transfer sandy or lump materials, or packaged materials. According to different transferring equipment, the transfer system can be one alone or multi-conveyors or combined with other transfer equipment or packing machine, printing and coding machine. The belt conveyor can be installed horizontally or to meet the needs of different transfer lines.
