A kind of complex Copper slag has been studied. The runofmine grade of copper was %. Through the research of the flotation separation test, the optimal grinding fineness () was about to 75%. The optimum kind and dosage of collector was 150 g/t Y89. The dosage of sodium silie which was the Slime dispersing agent was 1000g/t. The dosage of sodium carbonate was 800g/t.
A flotation process in which copper ores or copper converter slags are ground and firstly have added thereto benzotriazole or alkyl benzotriazole as an activator and secondly one or more collectors selected from the group consisting of xanthates, dithiophosphates, thiocarbamate esters, dithiocarbamates, mercaptans and dixanthogens and further, if desired, a promoter such as kerosene, light oil ...
· The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na 2 S, CuSO 4, and FeCl 3 on sulphidizing flotation of copper oxide. The results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe3#x2b; inhibits the sulphidizing effect.
In the first flotation stage, as much copper as possible is recovered in a rougher concentrate so that as little as possible goes to the tailings. To increase the copper recovery rate, often these tailings are leached with sulfuric acid. After regrinding, the rough concentrate is 2 of 11cleaned in several flotation steps. After sedimentation in thickeners and filtration in automatic filter ...

· The waste copper slag was collected from a domestic copper smelting plant, where most of the coppercontaining materials in the slag were recycled through the flotation process. The obtained samples were weighed and dried in an oven at 110 °C for 24 h. The moisture content of the waste copper slag was measured according to the variety of the mass before and after drying. Then, the .
Nickelcopper converter slag 'A' 100 kVA and 200 kVA. Using converter slag from a nickelcopper plant, tests were carried out, in 1990, on a 100 kVA furnace (operated at 30 kW) and on a 200 kVA furnace (operated at 85 kW), at low additions of reductant (in order to minimize the reduction of iron).
· The content of copper in the flotation tailings directly depends on fragmentation rate (Figure 1). Expected content of copper in the flotation tailings, in the case of cooling in pits, is %, and in the case of cooling in pots, from to % Cu. Fig. 1. The effect of fragmentation rate on the slag flotation [6]

BHP Olympic Dam engaged Outotec to design and construct the Slag Flotation Plant on the Olympic Dam process plant site to treat recovered slag product from the smelter to increase copper production and make the facility more economical. JTMEC provided electrical construction engineering support services during the project for Outotec to ensure the project was constructed to BHP standards in ...
Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, runofmine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is delivered to the crusher(s) to be reduced in size. At this stage, much of the moisture ...
Pine oils, cresylic acid, and longchain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarifiion and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium, lead, selenium, magnesium, aluminum, cobalt, tin, nickel, tellurium, silver, gold, and ...

the classical processes of flotation and pyrometallurgical extraction. Seven copper smelter plants, which extends from the northern Atacama desert to the central part of the country produced 1,522,000 metric tons of fine copper in 2002, approximately one half of total copper concentrate production, with a notorious environmental impact due to the great amount of slag produced during these ...
· In the smelting plant of Karadeniz Copper Works (KBI) (Samsun/Turkey), the copper slag produced is treated through a millingflotation process to reclaim the copper lost to the slag phase. Annually about 150 000 tonnes of flotation wastes are generated and disposed of on the flood plain Yeşilırmak River Delta where, over the years, approximately –2 million tonnes of slag have already ...
