Enhancing the flotation recovery of copper minerals in
2020-1-1 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

The recovery of copper, by flotation, from calcium-ferrite
2004-4-1 The comparative copper flotation behaviour with respect to the (pilot plant) slag type was considered in terms of the overall selectivity of copper over the main gangue element, iron, in the flotation tests conducted. A selectivity plot for four of the flotation tests undertaken is presented in Fig. 7. In this plot, points on a line with a

The Recovery of Copper from Smelting Slag by Flotation
2017-2-8 Abstract. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.

Flotation of copper sulphide from copper smelter slag
2015-10-10 Lowest copper recoveries were obtained with alkyl hydroxamate in single collector floation performance. It has been reported that the alkyl hydroxamate is not very selective for sulphide flotation. In case of copper slag most of the copper occur in the form of copper sulphide and shows very low response with alkyl hydroxamate.

Characteristics and utilisation of copper slag—a review
2003-11-1 A flotation scheme used at the Almalyk copper smelter for processing slags together with Cu–Mo ores was described, and ways to optimise the slag flotation process were examined (Sigedin et al., 1986). Results of the flotation of converter slag were presented, and the effect of the combined flotation of slags with the ores on the recovery of

These operations also produce two additional slags, the so-called soda slag and copper slag respectively. The quantity of these slags is much smaller than that of the combined quantity of the silica slag and lead slag (dore slag). These additional slags were not subjected to grinding and flotation in accordance with this invention.
