Management of copper pyrometallurgical slags giving
gravity varies with iron content, from 2.8 to 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. Granulated copper slag is more porous and, therefore, has lower specific gravity and higher absorption capacity than air-cooled copper slag. The
Copper Slag an overview ScienceDirect Topics
The density of copper slag varies between 3.16 and 3.87 gcm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 gcm 3, which means copper slag is denser than ordinary natural aggregates. In general, water absorption of copper slag is very low.

TENORM Copper Mining and Production Wastes
Copper smelting and refining facilities produce 2.5 million metric tons MT of smelter slag and 1.5 million MT of slag tailings per year. This is a large volume of slag, however, it is very small compared to comparable waste volumes from mining and crushing operations.
Copper Recovery in Smelting Slag Recycling
Copper smelting slag is the solid waste generated in the process of smelting copper. Due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper. Disposing and recycling copper can effectively reduce the waste of useful resources, while generating considerable economic effectiveness.
PDF Partial Replacement of Copper Slag as Fine Aggregate
Copper slag is an industrial by-product material produced from the process of manufacturing copper. For every ton of copper production, about 2.2 tons of copper slag is generated. It has been estimated that approximately 24.6 million tons of slag are generated from the world copper industry.
Behavior of copper and lead during mineralurgical and
There are only a few smelters processing copper concentrates directly into blister copper. Despite the many advantages of this process, a serious challenge of this technology is the need to process the resulting flash smelting slag. It contains 1215 copper and 2.54 lead. In this form, it cannot be considered as waste material and, therefore, a high-temperature reduction process is ...
