Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide.
The tailings consist of fine and ultrafine particles under 70 mesh, which have previously passed through a stage of grinding and flotation in the mine of 'El Teniente', a branch of the national copper company CODELCO Chile, a mill plant located in central Chile.
in mining activity for storing tailings from the copper ore flotation process until 1989. The main materials forming the tailings are silica (quartz), carbonate minerals (dolomite, calcite), and clay minerals, as well as to a lesser extent shale copper ores, marl, shale, and anhydrite.

In the Katanga province of the Democratic Republic of Congo (DRC), effluents from flotation of oxidised ores of copper and cobalt are stored in settling ponds in view separation of tailings and ...
was 87% while copper and zinc extraction was % and %, respectively. Thus, it was shown that biooxidation of old pyrite flotation tailings with application of acidophilic chemolithotrophic microorganisms for recovery of copper, zinc, and gold could be .
copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings. As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used [12].
on its flotation was studied in a typical copper ore. A twostage (Cu and pyrite) rougher flotation indicated that maximum Au recovery (95%) can only be achieved with pyrite flotation (recovery, 93%). A decrease in grind size of the flotation feed from 70 µm to 38 µm and without pyrite flotation stage
After flotation separation of the molybdenite from the other minerals (cleaner stage), the tailings were transferred to the cell of the Cu flotation system. The beneficiation flotation flow sheet of industrial tests was based on the developed benchscale flow sheet, as described in section
flotation tailings containing significant amounts of copper. It is estimated that the old flotation tailings of the Copper Mine Bor, used from 1933 to 1987, contains about 27×106 tons of tailings with an average copper content in the range – wt. %, a gold content of – g .
tailings and as a result, the mining company plans to move the tailings using a slurry approach to a place where a copper smelter is located. These copper tailings have trace concentrations of Fe, As, Mn, Hg, Zn, Se, and Cd The iron oxides and sulfides cause acid generation and .
The Hellyer ore benchscale process flowsheet was similar to that of other copper, lead and. zinc concentrators. However, the metallurgy was considered sufficiently difficult due the fine. particle liberation sizes and the slow flotation response to warrant pilot plant operation.

Copper tailings: if the copper with high heavy metals content, the separation will be easier and apply the process of flotation. If there exist magnetite in the copper tailings, it will firstly using acid leaching to precipitate the copper, then use magnetic separation accordingly.

ABSTRACTAqueous slurries' dewatering using gravitydriven thickeners is an essential unit operation in mineral processing. Thickener feed dilution is often used for enhanced flocculation and sediment compressibility. This work investigated the effect of feed dilution on thickener performance for copper flotation tailings.
sulfidic flotation tailings can be environmentally hazardous as they oxidize when exposed to water and oxygen. This reaction produces acidic wastewater and sulfates, which are environmentally hazardous [6]. Thus, various hydro and pyrometallurgical methods and mineral processing technologies have been explored for reprocessing the tailings [4, 5].
Flotation tailings are a free and abundant material. Treatment of flotation tailings with acidic effluents results in leaching of residual copper from copper oxide minerals, leading to increased concentration of copper in the leach solution.
