Copper Slag - an overview ScienceDirect Topics

The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. 200 sieve) in size. The air-cooled and granulated copper slag has a number of favorable mechanical properties for aggregate use, including excellent soundness characteristics, good abrasion resistance, and good stability. It has high friction angle due to a sharp angular shape.

Characterization of Copper Slag SpringerLink

Copper slag can be treated as a secondary resource since it usually contains a substantial amount of copper and other valuable metals. Characterization of the slags to determine the expected metal recovery is essential for the design of separation flow sheets. In this study, the chemical and mineralogical composition of a copper slag from El Teniente, Chile were characterized. The copper content of the fayalite based slag is around 0.87 wt% which is higher than for certain copper

20/01/2019  Copper slag is one such industrial by- product generated when copper extraction is done by smelting from its ore. Generally, impurities floating on the molten metal during smelting are removed and quenched in large volume of water resulting in the formation of angular granules called as copper slag. In the past, attempts have been made to use copper slag in concrete production as aggregate
