Recovery of Cobalt and Copper from Nchanga Mines Slag ...

ferrosilicon has the potential to increase the plant recovery of cobalt and copper from the CRF slag and consequently discarded in form of slag. Referring to Figure 2, it can also be seen that an increase in coke dosage generally resulted in increased copper and cobalt recovery although the overall

Selective REE recovery from bauxite residue slags – Near ...

Jan 28, 2019 · The slags were cooled down at two different cooling rates (see Fig. 1). Subsequently, the leaching behaviour of selected rare earth elements (Sc, Y, La, Nd) by high-pressure acid leaching of the slag was analysed. Firstly, the REEs recovery by acid leaching of a slag with the highest content of aluminium, silicon and iron was studied.
