Gradation test was conducted on copper slag and sand showed that both copper slag and sand had comparable particle size distribution. However, it seems that sand has higher fines content than copper slag. Tests to determine specific gravity and water absorption for copper slag and sand were carried out in accordance with ASTM C128.

Abstract This paper studies the ferric sulphate leaching of converter slag (9% Cu) in order to recover Cu through a process in which bacteria regenerate the leaching agent. For this purpose, the effect of variables such as pulp density, ferric concentration, temperature and size particle have been investigated. As the Cu extraction is limited by the physical refractoriness of slag, a …
