associated costs. Batch testing at 900 C with the chalcopyrite-ferric sulfate system resulted in copper extraction exceeding 99 pct. At an optimal energy consumption of 1,520 kW· hjst, 95 pct of the copper was extracted. The pregnant liquor was clarified and tested for typical solvent -extraction recovery of the copper.

The evaluation of a copper flotation plant performance by plant survey and laboratory tests 99 Cu recoveries and flotation rate parameters of each size fraction were also calculated by using flow rates and Cu assays of the size fractions. It was observed that especially Cu recoveries of the fine size fractions were greater than that of the coarse

Using the criteria of recovery and rate, the flotation of the principal copper sulfides and pyrite with sulfhydryl collectors was found to follow the pattern: xanthate > dithiophosphate = thionocarbamate = xanthogen ethyl formate > dixanthogen.

The copper flotation waste (slag) generated from the copper industry is a by-product from the copper smelting industry [5–8]. The toxicity of the waste is determined by leaching tests and depending on the characteristics of the waste; the spent abrasive must be disposed of as solid or hazardous waste.

Copper flotation waste is an industrial by-product material produced from the process of manufacturing copper. The main concern with respect to landfilling of copper flotation waste is the release of elements (e.g., salts and heavy metals) when in contact with water, that is, leaching. Copper flotation waste generally contains a significant amount of Cu …

Evaluation of alternative flotation technologies 1181 When the three copper cleaners are included to make a four stage copper/nickel separation, the copper recovery drops to 80%, but concentrate grade, and Cu/Ni and Cu/Rk separation efficiencies increase to 9% copper, 77% and 68% respectively.

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
