· FeO + SiO2 FeSiO3 (Slag) Cu2O + FeS Cu2S + FeO • Slag floats over the molten matte of copper. 9. BESSEMERIZATION • Matte contains Cu2S and some unreacted FeO along with silica as impurity. • It is converted into copper in a special furnace which is known as "Bessemer converter".
The ISASMELT process is an energyefficient smelting process that was jointly developed from the 1970s to the 1990s by Mount Isa Mines (a subsidiary of MIM Holdings and now part of Glencore) and the Government of Australia's has relatively low capital and operating costs for a smelting process. ISASMELT technology has been applied to lead, copper, and nickel smelting. As of 2021, 22 ...

On the one hand, copper slag is nowadays a waste in copper pyrometallurgy despite the significant quantities of iron (>40 wt. %) and copper (1 to 2 wt. %). On the other hand, solar energy, when properly concentrated, offers great potential in hightemperature processes. Therefore, concentrated solar power (CSP) could be used in the treatment of copper slag to transform fayalite into magnetite ...
· A series of production technologies are described for gold recovery from complex gold concentrate blended with copper concentrate treated in the SKS smelting process comprising: 1) Feed preparation and proportionate feeding of complex gold concentrate and copper concentrate; 2) SKS smelting gold recovery operation and process control technology developed based on reaction .
the gold loss in slag on the mechanical loss of copper in it with a high correlation coefficient (r = ). An increase in mechanical losses of copper in slag from to % leads to an increase in the gold content in slag by more than times. An increase in the copper content in the form of sulfide in dust from to 3% increases the gold
2FeS + 3O 2 → 2FeO + 2SO 2 (g) Iron (II) oxide, FeO, slag is skimmed off. Relatively pure copper (I) sulfide, Cu 2 S, accumulates in the bottom of the converter. Air is blasted through this copper (I) sulfide to reduce the copper and oxidize the sulfur to sulfur dioxide: reaction. Cu 2 S.
· If this is a copper smelting slag, then it SHOULD be high in iron. Old copper smelting would typically use a reverb furnace, fed with copper concentrate and flux (silica and lime). The furnace would typically be fired with gas burners or oil burners, directly into the smelting chamber.
· Slag from the reactor and the converters is sent to the concentrator to recover the copper. This concentrate is fed back into the reactor, and the slag tails go to the tailings pond. The acid plant production is currently 525,000 tonnes sulphuric acid per year, and comprises the largest gascleaning installation of any acid plant in the world.
1. A method for preparing iron ore concentrates by recycling copper slag tailings, comprising the following steps: (1) purifying and absorbing SO 2 flue gas with a SO 2 concentration of mg/m 3 by using copper slag tailings slurry, discharging the slurry when a concentration of SO 2 at a flue gas outlet is greater than 100 mg/m 3, and conducting filtering; (2) adding iron powder to the ...

· I'm looking for a contact to a copper refiner. We have been tasked to clean up a superfund site that has million tons of copper slag and metal. We are able to concentrate it to 6070% copper but are having trouble finding a refinery. Any help would be greatly appreciated. Thank you in...
· gold processing gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into .
