copper slag recycling system

Copper Recycling - ScienceDirect

2014-1-1  Slag from copper-smelting operations usually contain between 1.5% and 8% copper depending on process used. After internal recycling, reduction and/or settling, the slag contains between 0.7% and 2% Cu and is often discarded. It is estimated that about 2.2 t of slag is generated per ton of copper produced.

2003-11-1  Air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from a low of 2.8 to as high as 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the material is typically very low (0.13%).
