3.3. Physical properties. The typical copper slag is generally black or dark brown in colour and its density is in the range of 3.2 – 4.5 g/cm 3, mainly depending on the content of Fe (Sarfo et al., 2017b).The average true density of copper slag is approximately 3.8 g/cm 3, which is denser than the ordinary natural aggregates (Shi et …

The reverberatory furnace slag that has been discarded in the vicinity of the Bor Copper Smelter, Serbia, is currently processed by flotation at the nearby Bor Copper Concentrator. The copper recovery was rather low (about 40%) mainly due to the presence of oxide copper and insufficient mineral liberation. In our previous work, we
