Leaching of copper and zinc from copper converter slag over 15 mt of dumped slags including converter slag flotation tailings which contain up to 6000 t copper and 60000 t zinc are produced yearly by the coppersmelting plants of the ural mining and metallurgical company ummc alone. 2012-5-1 The recommended technological parameters for leaching of copper (the most important component) from converter slag flotation tailings are: pulp density of 30% (w/v), pH 1.5, temperature of 70 °C, initial Fe 3 + concentration of 15.7 g/L, no aeration, leaching for 1.5 h. 2004-4-1 Flotation has been identified as the most economical option to recover the copper from direct copper converting slags (Somerville et al., 2000) where it has been estimated that a copper recovery from the slag of above 90% is required to make the overall single-stage copper making process economically feasible. 2021-12-4 The second route was flotation of the slags, roasting of the flotation tailings with pyrite and leaching. The second route was found to be suitable for 2013-6-5 Rao and Nayak [ 7] and Piret et al. [ 8] are among the researchers who managed to obtain 30–60 % of copper concentrates from the slag using grinding and flotation operations. Similarly, Somerville et al. [ 9] carried out the single-stage flotation process (rougher) on the converter slag and achieved 90 % copper recovery. 2017-2-8 Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD. 2020-1-1 They also reported that the copper content of most smelter slags is normally around 1–2 wt. % while that of the converter slag lies between 2 and 2.5 wt. %. This higher content for the latter is due to over-oxidation and entrapment of metal droplets during the converting process. 2021-6-17 copper flotation from converter slags in mongolia.

Three slags containing 1.6, 5.0, and 6.6 percent copper were used. More than 90 percent of the copper was recovered in a rougher concentrate leaving a 0.2- to 0.3- percent copper tailings The report describes laboratory batch flotation tests conducted on copper converter slags to evaluate the relative merits of recovering copper from slow-cooled versus water-quenched slags. Three slags containing 1.6, 5.0, and 6.6 percent copper were used. Flotation process for copper ores and copper smelter . 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, Copper Slag Flotation Plant Johannsoutdoor.

Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around 4 million tons of slag are disposed every year and another 40 to 45 million tons are historically cumulated [1]. 2021-12-22 Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50%. Arch Min Sci Vol 59 2014 No 3 P 821834. copper slag. In the copper slag flotation plant is achieved unexpectedly poor metal recovery of copper (31,66%), gold (22,99%) and silver (22,10%), with. 2recovery Of Copper And Cobalt From Converter Slag. Key Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The copper content of the slags range between 0.8 to 5 wt. % and this is considered Recovery of cobalt, nickel, and copper from slags, Nickel-copper converter slag 'A'- 100 kVA and 200 kVA. Using converter slag from a nickel-copper 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). 2021-10-1 The effect of grinding time on flotation recovery of copper smelter slags within the Bardaskan district, Iran was investigated (Shamsi et al., 2015). The results obtained for the flotation tests at optimal conditions showed a copper recovery of 79.89% after grinding the material for 85 min to a particle size of 80% passing 48 µm. 2019-9-20 Slags on an industrial scale: i recycling of the converter slag to the smelting furnace, ii cleaning of smelting and/or converter slags in electric furnaces and iii flotation. metallic copper and sulphide copper present in these slags can be floated very.Reutov d.s., kotelnikova a.l., khalezov b.d., korinevskaya g.g. studies and research 2-Recovery of Copper and Cobalt from Converter Slag with a.

The converter slag from a smeltery in Daye contains 2.01% copper. The floatability of copper has a significant influence on the flotation of converter slag. Flotation tests, contact angle tests and FTIR were conducted to assess the influences of pH and different flotation concentrators on its 2018-8-20 Key words: Converter slag, flotation, copper, cobalt, sulphurization. 1. Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around 4 million tons of slag are disposed every year and another 40 to 45 million tons are historically cumulated [1]. In recent years, there has been a move toward recovering copper from converter-type slags by milling and flotation. The term "converter-type slag" is intended to represent a slag that contains a high amount of magnetite (Fe 3 O 4) and a low amount of silica. At the present time actually all plants changed over to autogenous melting of copper-containing concentrates use the flotation of converter slags (CS) dropping in tails about 0.55-0.90 % Cu; it 2021-10-1 The effect of grinding time on flotation recovery of copper smelter slags within the Bardaskan district, Iran was investigated (Shamsi et al., 2015).
