Copper ore flotation Cell is a mineral separation and enrichment equipment based on the difference in hydrophobicity of the ore surface, copper minerals usually exist in the ore in a form of sulfide. According to the benificiation sequence of useful minerals, the copper ore flotation process can be divided into prioritized flotation, equal flotation, mixed flotation, and partial mixed flotation. The choice of flotation process depends on the nature of the ore, a full laboratory test and study is normally carried out by sample test before completion of the plant design.
-Crushing and screening grinding and classification
-Prioritized copper concentrate flotation
-Activated flotation of other concentrates
-Concentration and dewatering
-Thickening and tailing treatment
Firstly flotation process produces single copper concentrate while other concentrates are suppressed ; when copper concentrate at first stage of flotation is completed, and the rest of the other concentrate is activated and is carried out with flotation process respectively. The copper prioritized flotation benificiation process bears such advantages of much easy plant operation, strict control of chemical dosage and producing of high copper concentrate grade.
Roughing flotation to obtain coarse concentrate for grinding,Sweeping by flotationto obtain concentrate and tailings pulp.Raw copper ore transported to warehouse by the mine car for storage,Raw Ore sent to the jaw crusher for primary crushing through the electric vibration feeder,Crushed product is transported to the cone crusher for secondary crushing by the belt conveyor, andSecondary crushed product is sent to the cone crusher for secondary crushing.Ore after crushing and Screening sent into hopper for the ball mill grinding;Grinding product is sent to the hydrocyclone for classification.Stirring is carried out in the tank, and after stirring, the ore pulp enters the flotation machine for flotation.After the ore slurry passes through a copper rougher, the tailings obtained are scavenged, and the scavenging concentrate is returned to the copper rougher for repeated concentration.
Tailing Treatment Process
Scavenging tailings slurry is pumped to the thickening cyclone for thickening, and the concentrated overflow is conveyed Concentrate again in the high-efficiency thickener, the overflow water of the thickener is returned for reuse, the underflow is sent to the high-efficiency multi-frequency dewatering screen with the underflow of the thickening cyclone for filtration, the filtrate water is returned to the tailings slurry, and the filter cake is transported by a belt conveyor to the tailings pond. The concentrate obtained from copper roughing is put into the ball mill for regrinding.
