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.

Flotation of copper sulphide from copper smelter

10-10-2015  The information will help in the flotation of copper smelter slag for better copper grade and recovery. Abstract Present work focuses on the differences in the performances obtained in the froth flotation of copper smelter slag with multiple collector viz. sodium iso-propyl xanthate (SIPX), sodium di-ethyl dithiophosphate (DTP) and alkyl hydroxamate at various dosages.

Enhancing the flotation recovery of copper

01-01-2020  Slag cleaning can be divided into two types, first being the pyrometallurgical reduction and settling of liquid slag, which is performed in slag-cleaning furnaces, and the second type being the mineral processing-based slag cleaning of solidified or granulated slag by crushing and/or grinding followed by gravity concentration or froth flotation (Davenport et al., 2002).

RECOVERY OF COPPER FROM SMELTING SLAG BY SULPHATION ...

The reverberatory furnace slag that has been discarded in the vicinity of the Bor Copper Smelter, Serbia, is currently processed by flotation at the nearby Bor Copper Concentrator. The copper recovery was rather low (about 40%) mainly due to the presence of oxide copper and insufficient mineral liberation. In our previous work, we

COMPARATIVE RESULTS OF COPPER FLOTATION FROM SMELTER SLAG

Production of copper concentrate by flotation of smelter slag has started in 2001. Flotation concentrate goes to the Copepr Smelter once more for production of cop-per cathodes and the rough flotation tailings go to the flotation tailing dump. Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50%.

05-04-2015  The content of copper in the flotation tailings directly depends on fragmentation rate (Figure 1). Expected content of copper in the flotation tailings, in the case of cooling in pits, is 0.5-0.9%, and in the case of cooling in pots, from 0.22 to 0.35% Cu. Fig. 1.

Enhancing the flotation recovery of copper

Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue matrix.
