copper loss in the slag of khatoonabad flash smelting furnace is estimated to be about At present, the electric slag cleaning furnace is used for the recovery of copper from slag. however, due to low recovery efficiency of electric furnace along with high consumption of electrical energy and water, selection of a method to enable minimum energy consumption and maximum recovery of copper In this research, the recovery of copper from copper slag is investigated using hydrometallurgy method. slag samples were taken from al-shaheed state company. the results of the chemical analysis showed that the slag contained 11.4% of copper. the recovery process included two stages; the first stage is leaching using diluted sulfuric acid.
white pine reverberatory furnace slags contained economically recoverable amounts of copper for a variety of reasons. among them: white pine concentrates yield extremely high matte grades and viscous slags. the viscous slags hinder matte settling causing matte prill entrapment in the slag. white pines total refined copper output is accomplished through fire refining An innovative, economical, and environmentally sound hydrometallurgical process has been proposed for recovering cu, ni, and Co from copper-rich converter slag by organic acids. In the leaching experiments, the effects of organic acid concentrations, pulp density, temperature, and time were investigated. optimum recovery of 99.1% cu, 89.2% ni, 94% co, and 99.2% Fe was achieved in 9–10
copper smelting slag is the solid waste generated in the process of smelting copper. due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper. disposing and recycling copper can effectively reduce the waste of useful resources, while generating considerable economic effectiveness.laboratory and pilot plant investigations have indicated that copper recoveries of 50% can be achieved with fine grinding and flotation of a copper reverberatory furnace slag. microscopic and microprobe studies indicate that the recoverable copper is in the form of matte, chalcocite, and metallic copper; the percentage of copper in particles appearing to be copper-free was from 0.23 0.54%
abstract. 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 uctivity of the copper recovery from the slags, the reactive area between the slags and the carbon reducer should be as high as possible. In consequence, the effect of the reducers surface on the rate of the industrial slag reduc-tion was investigated in this study. the attempt in early investigation on copper recovery from the slag of di-

whyte, r.m. development of a process for the recovery of electrolytic copper and cobalt from rokana converter slag. in: jones, m.j. advances in extractive metallurgy 1977 pp.jun 01, 2015 introduction. slag examined in this study is defined as the predominantly silicate and oxide by-product derived from smelting metallic ore. the two main types of slag included in this discussion are from the primary production of ferrous ores, from iron and steel manufacturing, and from non-ferrous ores, from the recovery of base metals and some precious metals.
copper slag recovery. cal-chem metals is currently purchasing copper bearing slag from a variety of industries including copper rod mills, copper tube mills and other industries where there is a need to melt copper. byproduct of copper melting is the production of slag. cal-chem purchases this waste stream material and brings it to their 10.11.2020 copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
therefore, the recovery of the copper from this slag has a practical importance and heavily influences the operational costs. part of the copper in the slag is in form of fine inclusions suspended in the slag; however, the majority of the copper is dissolved in it. the slag cleaning process is carried out in an electric furnace with coke and copper to be recovered from a secondary smelting slag. under optimum conditions, more than 95% of copper could be recovered by only a limited recovery of cobalt, nickel and zinc could be achieved by roasting the preroasted slag with pyrite at 550 for with a 0.25 pyriteslag ratio. around

copper is recovered from copper-containing slag by putting the matte and slag in a molten state together in a slag treating furnace at a volume ration of more than the melts in the furnace being maintained under agitation so that the slag and matte are in intimate contact so as to efficiently transfer copper from the slag to the matte.what is claimed is process for the recovery of metal values from copper smelter slag material which comprises mixing with agitation a unit part by weight of slag and about a unit part by weight of concentrated sulfuric acid to form an acid-slag mixture, incorporating in the acid-slag mixture about a unit part by weight of water, and allowing the mixture to react to produce a dry, solid
copper slag contains iron in the range of 4245%, which can be recovered and recycled along with the contained copper to obtain an ironcopper alloy and a final slag rich in oxides. therefore, the present work shows the experimental results of the reduction of a flash smelting slag using coke as reductant up to 150% of the stoichiometric to produce a discard quality slag In this way the rhf slag mass and its copper content has a big influence in the copper recovery of the new ilo smelter. this paper discusses the operational issues and the actions that have been implemented in order to obtain a discard rhf slag.
