Slag cleaning processing can be divided into two types. The first is pyrometallurgical reduction and settling, performed in an electric or fuel-fired slag-cleaning furnace. The second is minerals processing of slow-cooled slag, including crushing, grinding, and froth flotation, to recover Cu from the slag.
For example, they can be cooled in the air or slow cooled in induction furnaces or water quenched before they are milled and subjected to froth flotation. The copper recovery from the converter slags will largely depend on this initial cooling treatment.

Flotation of copper sulphide from copper smelter slag The present work focuses on recovery of copper value by froth flotation from the copper smelter slag The QEMSCAN results revealed that copper is present in sulphide form in fayalite ironsilicate matrix and very poorly liberated and require fine grinding The present investigation has studied the respective roles of sodium isopropyl ...
Feb 05, 2021 Oxidized copper ores, mixed oxide-sulfide ores, and those sulfide ores too low in grade to concentrate by froth flotation are treated by various copper leaching methods. The principal copper oxide minerals dissolved by leaching are azurite, chrysocolla, and malachite, although varying amounts of cuprite, tenorite, and native copper also are ...
metals from these slags using froth flotation. The copper slag used in this study is a blended slag BS that is generated during flash smelting and converting. After coolingsolidification, these two slags BS are crushed, ground and treated by flotation. However, for reasons
Froth Flotation. Crushed ore is further processed at a mill to fine sand. Liquid is added to make a slurry copper ore and gangue Chemical reagents are added to bind the copper and make it waterproof Froth flotation by . Andreslan. Public . Domain via Wikimedia . Commons.

Bessemerisation of copper matte is done in Bessemer converter in presence of air. Following reactions take place- 2FeS 3O22FeO 2 SO2, FeO SiO2 FeSiO3 slag, 2Cu2S 3O2 2Cu2O2SO2, 2Cu2O2Cu2S 6Cu SO2 Melted copper is cooled, and then SO2 is evolved. such copper is known as BLISTER COPPER98Cu2 impurities
Aug 28, 2017 The subsequent separation of the metal and sulfides can be achieved by conventional magnetic separation and froth flotation or other mineral-processing techniques. The essentially chromium-free, nickel-rich components are then given a hydrochloric acid-chlorine leach HCl-Cl2 which leaves elemental sulfur as a recoverable residue.

Copper pyrites are concentrated by froth flotation process. In this process slurry of finely divided ore is taken in a large tank. Pine oil or eucalyptus oil is used as the frothing agent. Ethyl xanthate is added which is used as a collector it increases the binding force between ore particles and forth. A mixture of all these things is agitated by current of air and froth is formed.
Consequently, the slag must be treated either in a cleaning furnace or in a flotation mill. The tapped slag is slow cooled, crushed, and sent to a concentrator. Flotation produces a high copper content concentrate which is recycled to the smelting furnace feed preparation area. An iron-rich tailings 0.5 weight percent Cu is discharged.
