Copper slag, a waste solid produced in the copper smelting process, is a high-quality secondary resource with huge output. The recycling and utilization of copper slag is of great interest because it avoids the loss of valuable metals and the threat of harmful metals, and saves a lot of natural resources and energy. This paper firstly reviews the main methods for the …
The recovery efficiency of copper from the converter slag was 92%, while that from the smelter slag was 54%. Herreros et al. [ 48 ] studied the influence of stirring speed, …
There are several works in literature where SCM models were applied in recent years [128][129][130][131], for example, Nadirov et al. [128] model copper ammonia leaching from smelter slag ...
The optimum digestion temperature is 250oC, at which a high recovery of copper from copper slag is achieved. Figure 7. Copper in the residue at various digestion temperatures.
