Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further …

However, recovery of copper was about 4 percent lower for the high copper slag (sample C) and 23 percent lower for the low copper slag (sample A). Flotation tailings from the quenched slags ranged from 0.53 to 0.66 percent; slow-cooled slags gave tailings containing from only 0.26 to 0.39 percent copper with lowest analyses for 30-minute grinds.

Utilization of copper slag as binder in mine backfilling was studied by Peyronnard and Benzaazoua, 2011, Tariq and Yanful, 2013. It was identified that drying and milling of the slag would be required for such application. Also, lime and gypsum may need to be added to enhance the binding property of the copper slag.

During the 1980s, a Slag Mill was built to re-process old copper reverbatory slags by converter techniques producing granulated slag, which is passed to the Pb smelter to recover Pb and also Cu. Since 1997, the Slag Mill has been used to re-treat converter slag tailings (Tsumeb Corporation Ltd., 1987; Schneider

Blasting with copper slag is generally done for two different purposes. First of all, copper slag blasting is an effective way to remove mill scale, rust, dirt, paint and other coatings from metal surfaces. But copper slag blasting also serves another purpose. In fact, blasting can also be used to create a surface profile in a surface.

Copper Slag Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in embankment applications. Copper slag can readily satisfy the gradation and physical requirements of AASHTO M145. (11) Unit Weight: Copper slag has a unit weight of 2800 to 3800 kg/m 3 (175 to 237 lb/ft 3).

Slag is the term used to describe the totality of non-metallic co-products generated in the production of metals from their ore. The chemical composition largely depends on the type of smelted metal and the smelting technology [ 31 ]. Copper slag (CS) is a non-ferrous slag made in the process of ores smelting.
Details 
In appearance, slag looks like a loose collection of aggregate, with lumps of varying sizes. It is also sometimes referred to as cinder, in a reference to its sometimes dark and crumbly appearance. Slag is commonly used to make cement. This substance is produced during the smelting process in several ways.

A unique reclamation project to recover precious and base metals from the reprocessing of slag produced from the old smelters of copper ore. The silicate slag from old smelting operations was systematically deposited into a semi-homogenous pile, with significant amounts of gold and other valuable metals "locked up" in the slag material.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
Details 
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.
