Flotation machine can be used to separate nonferrous metal, ferrous metal, heavy metal, nonmetallic mine, chemical material and recycling minerals. Each chute can inhale gas, sink magma, separate. No assiting equipments are required, and Flotation Machine must be levelly installed. Flotation Machine is easy to change the flow chart. The cycling way of magma is very reasonable. Flotation Machine can reduce the impurities to a great extent. There is automatic equipment on the magma surface, easy to adjust. The impeller also owns the upper and lower retroversion blade. The upper one makes the magma cycle upward, while the lower one makes the magma cycle downward.
Flotation machine has many same characteristics with other machines, such as reliable working, wear-resisting, low power consumption, simple structure and low price. It also should have the special requirements like followings to meet the flotation requirements:
1. Well inflatable role: Flotation machine must guarantee a certain of air amount be absorbed or pressed into the ore pulp and disperses in all the slot. For the air can be dispersed more finer and more uniform, the contact between the ore grains and air bubbles will be more so that the flotation efficiency can be higher.
2. Mixing role: Flotation machine should have well mixing role to make the ore grains suspension and distributed in all the slot uniformly. At the same time, the machine can promote the solvation of some hard dissolved agentias, which is in favor of the full function between the agentias and ore grains.
3. Circular flow function: In flotation machine, the circular flow of ore pulp can make more contact between the ore grains and air bubbles.raymond mill:http://www.crusher-machine.com/13.html

4. Adjusting the ore pulp level: In flotation process, the thickness of the foam layer and pulp flow should be adjusted. At the same time, the aeration quantity of ore pulp and pulp circulation inside should also be adjusted effectively.
5. Continuous work: In flotation machine, raw ores, flotation concentrates and discharged tailings should be adopted continuously with dryer machine. Right bubble blowing machine and ore discharged institution are also needed.
In most instances, flotation is used for processing sulfide auriferous ores whose flotability is quite high and the effect is most notable. By flotation, the gold can be enriched to sulfide ore concentrate as much as possible and the abandoned tailings can be got. The ore dressing cost is also quite low. Flotation process can be used to process polymetallic ores, such as gold-copper, gold-lead, gold-antimony, gold-copper-zinc-lead, etc.
Certainly, flotation process has boundedness. For the ores with coarse grains, when the gold grains is larger than 0.2mm and the flotation gold is also larger than 0.2mm, the flotation is quite hard to process the gold ores. For the ore stones which is hard to obtain necessary flotation conditions, if the quartz quality gold ores do not have sulfide, after pulp mixing, stable flotation bubbles are hard to be got so the flotation has some difficulties. In the economic indicators. the flotation process needs a large amount of floating agents so the flotation processing cost is higher than gravity separation and patio process.
