High recovery grade, high grade, low operation cost, carbon steel made flotation column SRF-4510 in flotation plant
Flotation column is a type of flotation equipment which has profile of column or rectangular body without impeller or propoller inside, as an efficient and power-saving flotation equipment, it has high enrichment ratio, small area needed, low labour cost and better recovery rate on fine particles than conventional flotation machine.
Different from flotation machine, the air bubbles for flotation is generated by high pressure through a lance-type sparger, named micro-bubble generator. By this method, bubbles generated in column flotation cell will be much more and smaller than produced in flotation machine. It provide more chance of contact between mineral particles and bubbles. Furthermore, automatic adjustment valve will be used to control the slurry level in column, which ensure the whole flotation process functioning in stable condition.
During the last decades, flotation column has been installed as rougher, cleaer and scavenger in flotation course, applied in nonferrous metal minerals such as Mo, Cu, W, Fe, Pb, Zn and nonmetals like P, S, F.
Features:
1. High enrichment ratio;
2. Small cover area needed;
3. Low operation cost;
Sketch map of flotation column:
Parts:
Feeding system:It mainly includes buffer tank and slurry sprinklers.
Aerating system:It consists of air compressor, air storage tank, flowmeter and bubble generator. The high pressure air generated by air compressor goes through bubble generator, then forms much fine bubbles for flotation.
Level control system: It consists of ultrasonic level metre, PLC and tailing valve. When it functions, the floating ball is always on the interface of slurry and foam, ultrasonic level meter can detect the level of interface by floating ball, then PLC will adjust the open degree of tailing valve automatically according to customer’s require.
Bubble washing system: Mainly installed over the top of flotation column as cleaner. It can decrease the impurities content in concentrate.
