Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. This article focuses on industrial flotation, which consisted of two oneyear campaigns (2016 and 2017).

The special feature of LEGRAN’s metal slag processing system at the Lippe Plant is the way the material is treated. The slag and spent refractories need to be pulverised before they can be processed and this job is carried out by a rod and ball mill which dates back to the time when the site used to produce aluminium.

Copper slag is a by-product formed during the copper smelting process. The molten copper forms at the bottom of the furnace while molten slag is formed on top. The molten copper slag is then drained off and quenched with water or left in the air to cool. In Singapore, treated and processed copper slag (Mohs Hardness ≥6) is imported from various

Value-added Uses for Copper Smelting Slag . Proposed by Freeport -McMoRan Background Copper smelting is a high-temperature process that separates elemental copper from copper concentrates. Smelting leaves behind “slag” from the refining process. Once it leaves the smelter, the slag is poured onto the slag stockpile and is cooled in layers.

The main advantage of this type of furnace is strap slag processing possibility, while recycling copper containing materials such slag is formed and because of high zinc and tin containment such slags have high viscosity. The ability to mix producing slag allows to receive waste slag with low copper containment.

Air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from a low of 2.8 to as high as 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 (0.13%).

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
