The chemical composition of copper slag varies with the type of furnace. The typical composition of smelting slags is Fe (as FeO, Fe 3 O 4) 30–40%; SiO 2 35–40%; Al 2 O 3 up to 10%; and CaO up to 10%. The density of copper slag varies between 3.16 and
Copper Slag. Copper slag is an abrasive blasting grit made of granulated slag from metal smelting process ( also call iron silicate). Copper Slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for
Nov 01, 2012· For these conditions, the copper losses in the slag are roughly 75% as dissolved copper and 25% as entrained matte and copper. Such conditions include operating the electric furnace at metallic copper saturation, maintaining the %Fe in the electric furnace matte between 6 wt.% and 9 wt.%, not exceeding a slag temperature of 1250°C, and controlling the Fe/SiO<SUB>2</SUB> ratio
Nov 10, 2020· Copper slag is a by-product created during the extraction of copper from copper ore. Copper slag has also gained popularity in the building industry for use as a fill material. Unlike many other fill materials, it poses relatively little threat to the environment.
The Industrial Copper Slag given by us to our clients is essentially a residual substance secured from the processing of smelting ore. We offer our clients impeccable quality Copper Slag Powder which is 100% processed and widely used for blasting and removing wastes from metals.
Copper slag, a by-product of copper pyrometallurgy, inevitably contains a certain amount of copper.
Copper slag is an abrasive blasting grit made of granulated slag from metal smelting process ( also call iron silicate). Copper Slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-21/2 and SA-2.
The produced slag from each of the two slag blows is transferred to the slag cleaning furnaces (along with flash furnace slag) for cleaning prior to discharge, while the high copper slag from the

Dec 29, 2017· In this context, “tailings” is waste rock at a mine after the ore has been processed to remove the metal. It has usually been pulverized to fine sand. “Copper slag” will be the slag skimmed off molten copper in a furnace. It is generally formed fr...
A charge of the copper-bearing slag material is treated in the first stage of the process with a hydrocarbonaceous or hydrogenous reductant in a rotary furnace, such as a top-blown rotary reactor, rotating at at least about 10 rpm, to form a high-grade copper matte phase and a slag phase of reduced copper

Copper slag enacademic Copper slag is an abrasive blasting grit made of granulated slag from metal smelting processes (also called iron silicate) Copper slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc Suitable for SA-3, SA-2½ and SA-2 [24/7 online]
The melt of copper slag prepared in the furnace 1 is guided into the second furnace 2 via connection means 8 in the form of a melt channel. Two electrodes 9 and 10 in the form of graphite electrodes connected to an AC source 11 penetrate into the first furnace 1, namely, into the molten slag located in this furnace.
Copper Slag an overview ScienceDirect Topics. Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper
holding furnace (RHF) slag, which were experienced at the Xstrata Cop- drop copper content in slag from 0.6 to 0.5%. The chemical soluble copper loss in RHF slag is about 0.2%
Nickel-copper furnace and converter slag -200 kVA. During 1995, a campaign was undertaken on the 200 kVA furnace with the intention of combining furnace slag with the converter slag previously treated. When treating furnace slag containing 0.22% Co on its own, the maximum cobalt recovery that could be obtained was 66%, with a cobalt value of 0
Table 9: Performance of slag cements prepared by using 35% copper slag at different fineness. Observation and Analysis: Chemical analysis of granulated blast furnace and copper slag are given in Table 1. The results indicate that granulated blast furnace slag conforms to all the requirements of Indian Standard Specification IS: 12089-1987 for the manufacture of PSC unlike copper slag.
Dec 01, 2002· Recycling copper converter slag back to the flash furnace has been practised in some plants and it leads to an increase in the matte grade (Antonioni et al., 1981). In some plants, flash smelting furnace slag (1.6–2% Cu) and converter slag (5–7% Cu) are cleaned in an electric arc furnace, where coke is used as reductant and copper content
Oct 05, 2020018332Copper slag cleaning in an electric furnace is a critical process for reducing the excessive magnetite Fe3O4 present in the copper slag to decrease the slag.
Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.
