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.
