Foam flotation machine

This type of flotation machine is introduced from the upper part to the foam bed instead of the ore pulp area. Its characteristics are as follows: the ore particles with large floating ratio; the treatment capacity is very high at the same speed, so the cost is low, especially the power consumption is very low; because the coarse particles can be treated, the grinding and dehydration costs are greatly reduced; the relationship between the recovery rate and the flotation time is changed; when the retention time increases, the recovery rate decreases and the grade increases, which is contrary to the situation of the pulp aerated selection machine.

(5) Flash flotation machine

This is a new type of skim air aerated bubble flotation cell, which is of great significance for gold flotation, especially for those flotation plants whose tailings are not cyanide leached (such as copper gold ore). Due to the high density of gold and some gold minerals, it means that they are continuously circulated in the grinding and classification circuit, and can be discharged from the cyclone classifier only after grinding to enough fineness. Like other minerals, the particle size is very small, which will affect the flotation effect. The installation of flash flotation machine in the flotation circuit can improve the recovery of monomer gold with less dosage and faster flotation speed. The control of the foam layer is very important. If the load of the foam is very high or the concentrates are coarser, the stability of the foam will be reduced.
