Analysis Of The Flotation Behavior Of Complex Copper Ore

Flotation tests were conducted on a Chilean copper ore containing chalcocite, bornite, and chalcopyrite using a Denver-type flotation cell at 0, 50, 100 gt NaHS and pH 8, 9, 10. At several points in the flotation tests, solutions were sampled for analysis of S ion in the solutions.Flotation tests were conducted on a Chilean copper ore containing chalcocite, bornite, and chalcopyrite using a Denver-type flotation cell at 0, 50, 100 gt NaHS and pH 8, 9, 10. At several points in the flotation tests, solutions were sampled for analysis of S ion in the solutions.A total of 1700 kg of ore was processed through a continuous circuit which included grinding, gravity concentration and flotation to recover the gold and copper values in the ore. The following table summarizes the metallurgical balance. The gold feed grade is back-calculated from the products to be 27.8 gt or 0.89 opMT.

The crushed ore is fed to two semi-autogenous SAG grinding mills, followed by two ball mills and one regrind mill. Flotation circuits are then used to produce a gold-copper-silver concentrate.

Copper Pyrites Is An Ore Of Copper I Describe The

Copper pyrites are concentrated by froth flotation process. In this process slurry of finely divided ore is taken in a large tank. Pine oil or eucalyptus oil is used as the frothing agent. Ethyl xanthate is added which is used as a collector it increases the binding force between ore particles and forth. A mixture of all these things is agitated by current of air and froth is formed.Copper pyrites are concentrated by froth flotation process.

READ PAPER.Conventional and column flotation cells are well suited for concentrating ores ranging from 50-150 micron. h owever, their effectiveness when treating particles coarser than this threshold is suspect due to turbulence and buoyancy issues. Process engineers no longer have to try to achieve optimum performance in a single unit operation.
