123 Primary Copper Smelting. 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 ...
Mintek has been working on the recovery of cobalt, and the associated valuable metals, from slags, since 1988, using DC-arc furnace technology to effect selective carbothermic reduction of the oxides of cobalt, nickel, copper, (and zinc, where present), while retaining the maximum possible quantity of iron as oxide in the slag.
Sep 21, 2012· The electric furnace or rotary slag-cleaning furnace are now generally used to perform this task, giving a level of copper in discard slag typically in the range of 0.55 wt.% and 1.3 wt.%, with most plants reporting copper losses in the discard slag in the range of 0.8–1.0 wt.%.
Oct 02, 2019· 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.
The copper ore become molten copper droplets that fall to the bottom of the furnace forming a molten copper layer with a slag floating on top of it. The molten copper is tapped and sent through the same processes as the reverb smelted copper, except for the converter stage, as it has been already converted to blister copper in the flash furnace.
the slag the reduction of copper losses in the slag or the slag cleaning process could be suggested [3, 4]. In that context, this paper investigates the abundance and distribution of species of copper in various types of slags (flash smelting furnace slag, electric furnace slag and converter slag.
Copper Slag. We are leading manufacturer, Supplier & exporter of Copper Slag. This product is appreciated for its hardness and free from silica. Our products are made up of using premium quality granulated slag in order to maintain their adherence to universally accepted norms.
Description: Copper slag is a by-product produced during smelting of copper, which is then processed into abrasive products. Typically it is composed of Ferro silicate material and oxides formed when the molten slag is quenched in cold water.
All Coal & Copper Slag Abrasive Coal slag is a glass matrix alumina-silicate which is produced as a by-product of coal burning power plants. As it burns, the residual ash becomes molten. When this slag is cooled, it vitrifies into a glassy, abrasive material, which is then crushed to produce blast media. ...
Granulated copper slag is more porous and therefore, has lower specific gravity and higher absorption capacity than air-cooled copper slag. The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. 200 sieve) in size (Emery, 1986, Hughes and Haliburton, 1973).
Recovery of copper from copper slag and copper slag flotation tailings 77by oxidative leaching Leaching with ferric sulphate The slag and the slag flotation tailings were leached with ferric sulphate in 1 M sulphuric acid. The ferric iron concentration was varied in the range from 5 g/dm3 to
Secondary copper blast furnace slag was treated with carbon to derive the conditions for maximum recovery of copper with minimum simultaneous reduction of iron oxide.
Consequently, wet-charged reverberatory furnaces have less copper in their matte product than calcine-charged furnaces, and they also have lower copper losses to slag. Gill quotes a copper in slag value of 0.23% for a wet-charged reverberatory furnace vs 0.37% for a calcine-charged furnace.
PDF | Copper loss in the slag of Khatoonabad flash smelting furnace is estimated to be about 1–3 %. At present, the electric slag cleaning furnace is used for the recovery of copper from slag.
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.
Electric Arc Furnace Slag (EAF or steel furnace slag) Produced when scrap metal and fluxes are oxidized by the use of an electric current. Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include
Copper loss in the slag of Khatoonabad flash smelting furnace is estimated to be about 1–3 %. At present, the electric slag cleaning furnace is used for the recovery of copper from slag. However, due...
Dec 28, 2017· What is copper tailing and copper slag? There are two typical deposits which ultimately yield copper. Ores and Sulphides. Copper is typically only present at a 1% level in the mined material. In mining copper, one usually crushes the ore to a fine...
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% ...

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 concentrates now available. The global production of refined copper over the past eight years is ...
possible option. The copper slag contains a high content of silica and iron. The solution final pH is the most important factor affecting the removal of iron and silica from the leach solution and the overall metal recovery. Fe removal from the leaching of copper slag is done by the formation of a metal hydroxide.
A slag by-product of such workings was a colorful, glassy, vitreous material found on the surfaces of slag from ancient copper foundries. It was primarily blue or green and was formerly chipped away and melted down to make glassware products and jewelry. It was also .
Secondary copper smelters are also a source of copper slag. These smelters recover copper from scrap copper alloy products such as telephone switching gear, electronic hardware, wrought products, and wire. Such slag may contain alloying elements (e.g., beryllium or iron). Beryllium is toxic,
