Accompanying with the pyrometallurgical processes of copper, a large number of copper smelting slag is generated, in which. the average content of copper reaches more than 1% (reaching or even exceeding China s copper ore grade for smelting). Chinas output of copper slag is up to 15. million tons per year [2].

Abstract. Coal gasification fine slag is a solid waste of difficult-to-separate nature. In this study, the residual carbon was enriched from fine slag by conventional flotation. The optimal flotation results in the concentrates yield of 59.01%, the concentrates ash content of 37.64%, and the flotation perfect index of 41.12%, respectively.

The analytical results in Table 1 show that the slags tested varied in total copper content from 5.2% to 15.1% Cu with the ndida slag having a mid-range value of 9.8% Cu. The CaO/Fe ratio was typically 0.63 except for the ndida slag where it was 0.55. In general, the higher the copper content the more oxidised the slag.
