How to Recover Copper from Slag by Flotation
03/02/2021· The bulk of the world’s output of copper is produced by smelting copper sulfide flotation concentrates in reverberatory furnaces, followed by oxidizing the matte to blister copper in a converter. Slags produced in the converter are too high in copper to be sent to the dump and are returned to the reverberatory furnace for recovery of most of the copper. This method forRecovery of metal values from copper slags by flotation,,The second route was found to be suitable for the treatment of the copper slag studied.

Today, the reserves of this material are evaluated at about more of a year, with the average copper content of 0.6-0.9%. Production of copper concentrate by flotation of smelter slag has started in 2001.
RECOVERY OF COPPER FROM COPPER SLAG AND COPPER SLAG,
Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings.Copper Sulfide Flotation - Mineral Processing & Metallurgy,13/04/2016· Copper Sulfide Flotation Circuit. Beneficiation of Copper Sulfide by Flotation. Copper, due to the present world demand and price, is of foremost interest to the mining industry. Many new properties are either in the process of being brought into production or are being given consideration. Copper minerals usually occur in low grade deposits and requireRecovery of Copper from Reverberatory Copper Slag and,,because copper slag has a bond work index of 22 kWh/t and is thus a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption. The present work shows that digestion of the milledCopper Recycling - ScienceDirect,01/01/2014· Slag Treatment for Recovery of Copper. There are several options to treat slag, depending on the metal content in the slag. Flotation can be used for slag that has been slow-cooled, crushed and grinded. Mere settling of the slag to allow mechanically entrained matte droplets to settle and thus be separated from the slag can be obtained in electric furnacesWorld Copper Slag Flotation Plant,Copper Recovery Through Smelter Slag Flotation in.This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests.
