The Improvement in Flotation Cell
According to the characteristics of flotation subject, people often complete the check, record, adjustment and stability work of operating parameters by using automatic instrumentation and control devices, the flotation separation process control usually includes flotation process equipment order control, Administration of the amount of feed forward control, the slurry pH value control, pulp potential control, pulp flotation inflatable control, flotation cells level control.
Flotation machine is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
The impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp; on the other hand, to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board.
When flotation separator works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remained slurry flows to the next trough until it becomes residue.
When we floating the iron ore, the pulp are generally required to heat up to about 35 degrees to accelerate the collecting agent dissolved and improve the flotation effect. To solve the harmful effects of the fine mud in flotation separation process, sometimes the precipitation-flotation can be adopted. Using the flotation method, the magnetite concentrate can be obtained, the super-high-purity iron ore concentrate can also be obtained, or recycle associated elements from iron ore.
