Dec 01, 2017· Flotation of ground copper slag was also studied by Bruckard et al. (2004). According to them, using a two-stage flotation process, 80–87% Cu can be recovered from the copper slag. Using additives with ground copper slag, Guo et al. (2016) performed re-melting followed by flotation and magnetic separation to recover Cu and Fe. They indicated ...

Smelter slag is initially deposited in piles. These slag piles range in surface area from one to 75 acres, and in height from three to 45 meters. Slag is associated with smelter operations, which may or may not be co-located with the mines. Copper slag can be used either as sandblast grit or an admixture in concrete. Top of Page.

Copper Slag General Information, Process, Products .. · Copper slag is a by-product created during the copper smelting and refining process. Copper slag is a by-product obtained during the production of copper metal, which can be used as pozzolana in the production of cementing materials.

Two types of slag can be produced: an air-cooled copper slag with light black color and a glassy appearance, and granulated copper slag which is porous with a vesicular structure. 26 The specific gravity of copper slag varies as a function of the iron content, between 3.2 and 3.8 kg/m 3, and its water absorption is typically very low (<0.2 wt ...

Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.

Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. The slag forming reaction is: FeO + SiO 2 → FeO.SiO 2
