Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal...

with about 45–75% copper. This process is typically done in flash furnaces. To reduce the amount of copper in the slag material, the slag is kept molten...

An estimate of 2.2–3 tons of copper slag is generated per ton of copper produced, resulting in around 24.6 tons of slag per year, which is regarded as...
