The chemical compositions of copper slag used in this study are given in Table 1. The total iron content of copper slag is 39.85%, and the content of SiO 2, Cu, Pb and Zn are 30.81%, 0.33%, 0.22% and 2.81%, respectively. The minerals of copper slag determined by X-ray diffraction (XRD) are mainly fayalite and magnetite, as shown in Fig. 1.
The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ~50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist, 1978).Unlike the system for lead, the copper and Cu 2 S melts are nearly immiscible ...
Ore crushing and screening, grinding and classification are essential preparatory work before separation to get proper ore size. There is a balance to keep proper ore size neither too rough (insufficient liberalization) and too fine (over-crushed) in order to achieve high recovery rate and high efficiency.

Slag is a common raw materials for cement industry. The hardness of slag is around 6-7 in Moh's scale (harder than cement clinker). For the aim to grind slag (15-20 mm) to a final fineness of 30 microns. After the slag dry, the slag less than 50mm fed into the rolling mill, the slag will […]
Fire refining of blister copper is a singular process at very high temperatures (~1400 K), which means the furnace is exposed to heavy thermal loads. The charge is directly heated by an internal burner. The impurities in the charge oxidize with the flux of hot gases, creating a slag layer on the top of the molten bath. This slag is periodically removed, which implies liquid metal flowing ...
The invention relates to a method for reducing and extracting copper smelting waste slag through microwave carbon heating, which comprises the following steps: pulverizing copper slag, reducing agents (one material or a mixture of several materials in anthracitic coal, graphite, refinery coke and coke) and calcium oxide or calcium carbonate; mixing the ingredients; adding binding agents for ...

Possibilities for minimizing copper losses in converter slags include: (1) settling the molten slag to recover entrained matte and copper, (2) smelting the slag with a suitable reductant to recover a copper-iron alloy or a low-grade matte. (3) beneficiation of slags by magnetic separation, and. (4) treatment of the slag by flotation.
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).
