definitive flotation tailings from copper smelter slag goes to disposal on flotation tailing dump. Ten years ago, the mentioned useful metals are obtained by flotation concentration in the plant in Bor but with a series of difficulties and less successful than in the world with similar raw materials. Re garding to this, there are a number of difficulties, such as high power consumption and ...

copper extraction from flotation tailings, technological testing of sulphide oxidation from flotation tailings was carried out in order to increase the degree of copper leaching. 2. EXPERIMENTAL TESTING WITH THE DISCUSSION OF THE RESULTS The samples of tailings from depth of 14m were used for testing with four different loions marked with B1, B2, B3 and B4, whose chemical ...
The flotation tailings pond of the Bor Copper Mine poses a great ecological problem not only for the town of Bor but also for the surrounding soils and watercourses. Since the old flotation tailings contain about % of copper on the average, we investigated their leaching with sulphuric acid in the absence and presence of an oxidant. The aim was to determine the leaching kinetics of copper ...
Copper content in the flotation tailings had been changing in the same period from % at the beginning to less than % at the flotation process ending, depending on the copper ore quality and the flotation process parameters applied at that time. Characterization of the OFT In order to perform characterization of the flo tation tailings from Fields I and II, sampling was carried out by ...

As copper sulfides are acid soluble, copper from flotation tailings can be leached by sulfuric acid –6 Another approach for the recovery of copper from tailings would include the use of acidophilic iron oxidizing microorganisms. This process is referred to as "bioleaching".8 It is generally known that many acidophilic microorganisms provide metabolic energy by oxidizing ...
Copperzinc concentrate contained % of iron, 16% of copper, and % of zinc. Agitation leaching of old flotation tailings with distilled water and sulfuric acid solutions (of to 10% H 2 SO 4) for 3 h at pulp density of 20% made it possible to extract of 26 to 34% and of 58 to 70% of copper .
