This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a "Grade/Recovery Curve".

R. Dunne, in Gold Ore Processing (Second Edition), 2016. 6.2 Depression of Sulfide Minerals With Cyanide. The depressing action of cyanide on pyrite during froth flotation is well known (Sutherland and Wark, 1955) and is widely exploited on many flotation plants to selectively separate copper minerals from pyrite.Depression of pyrite by cyanide during froth flotation appears to take place in ...
Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is the froth flotation of finely ground ore. Froth flotation involves attaching fine Cu-sulfide mineral elements to bubbles and floating them out of a water–ore mixture. The flotation is made ...
The flotation concentrate contained 7.79% Cu, 22.00% Pb, 4.81% Zn, 8.24% S, and 12.15% CaO; copper sulfide accounted for 76.97% of the copper, lead …
As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest. These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about 5.6% zinc as marmatite; and was treated in a circuit made alkaline with lime, using pine oil as a frother and ...
which has 250.9 initial copper concentration. Two step flotation test was applied to remove . copper from solution, 94.7% copper removal was achieved with the 13.2 ppm c opper .
Jan 01, 2003· The presence of different sulfides dissolved during the bioleaching can affect the copper mineral leaching. The consequence of pyrite addition was to increase the Fe 3+ ion concentration, the [Fe 3+ /Fe 2+] ratio and the redox potential of the solution.The changes in the surface areas clearly demonstrate the important role played by pyrite addition in the microbiological leaching of flotation ...

Flotation Concentration Elmhurst College. Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. Contact Supplier. 1 Froth Flotation Fundamental Principles
copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant. It was established that recovery of copper and cobalt from this ore with hydrometallurgical treatment is not economical, so using flotation to increase the concentration of copper and cobalt was chosen. When flotation of the oxidized copper

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of ...
