Slags are sometimes treated by slow cooling, milling, and flotation. This approach is satisfactory when the metals in the slag are in either the sulphide or metallic form, but is not suitable for the recovery of oxidized metals.

The cost advantage of processing quenched slags results from elimination of the slow-cooling and crushing operations inherent in the treatment of slow-cooled slags. (2) Flotation of slow-cooled slag yields a slightly higher copper recovery and a lower copper tailing. (3) Quenched slags are more difficult to grind than slow-cooled slag.

Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. This article focuses on industrial flotation, which consisted of two oneyear campaigns (2016 and 2017).

Thus, the downside was that the fraction recovered from the slag after controlled cooling, milling, and froth flotation with a high yield of copper and its impurities (As, Sb, and Pb) was fed back to the smelting cycle where it constantly increased the impurity amounts together with the flue dust circulation from the off-gas train.

In terms of copper recovery, it is thus quite important how the copper slag has been processed and cooled post the smelting or converting furnace, EF and prior to the milling and flotation step. Far less important, in this respect, is the actual smelting and converting technology upstream of the slag cleaning step.

Recovery of copper from copper slag by physical beneficiation using froth flotation was studied by Sarrafi et al. (2004). They used mercaptobenzothiazole (MBT) collector to recover the copper from the ground copper slag and indicated that a slow-cooled slag would be more favorable for better copper recovery.

droplets [6] into account, conventional slag cleaning techniques [7], such as slow cooling of the slag followed by milling and flotation [8], already cannot efficiently recover valuable metals lost in slags [9, 10]. These problems have been studied by some investigators[2, 4, 7, 11 -14]. The research results [15 ]
