Liu et al. [32] used copper slag as catalyst in the pyrolysis and gasification of biomass, and found that copper slag can promote the decomposition of tar and increase the gas yield. Zuo et al. [33] studied the mixed pyrolysis of copper slag and biomass, and determined the gas products. The results showed that copper slag can catalyze the ...
Abstract The traditional fossil reductant used in the copper slag cleaning process cannot fulfill the requirements of sustainable development of the copper industry. Therefore, a new approach of employing waste motor oil (WMO) instead of a non-renewable fossil reductant to clean copper slag (reduce magnetite concentration and …

We carefully study the operations of each facility to custom design a comprehensive program for transporting copper slag. Our services include: Transportation; Pot Carriers for molten slag, blister and matte; Slag …
The distribution of matte particles in each slag layer after cleaning was investigated in detail, which indicates that the copper content in the upper slag layer can be reduced to 0.56 wt pct via ...
a Spaniard, the copper ores were intermittently worked by Spanish colonists, Mexican nationals, and early American settlers, amidst much danger from Apaches. ˚en, in 1909, eastern investors transformed the area into one of the original por-phyry copper operations—industrial-scale copper mines complete with concentrating and smelting …
Fayalite is the main phase of copper slag and a type of Fe silicate glass that is composed of a polymerized network of silicate tetrahedrons, in which SiO 2 and FeO are generally considered as network formers and modifiers, respectively. The structure of fayalite is shown in Fig. 13 [107].In iron silicate glass, O 2− exists in the form of bridging and non …

According to our previous studies [22, 26, 29, 30], the oxygen carrier of copper slag (CS) had the highest reactivity when calcined at 1100 °C (1100CS).NiO could significantly promote the transformation of the NO x precursor, char nitrogen and tar nitrogen into N 2.Therefore, it was expected to improve the reactivity of the 1100CS …
1. Introduction. Copper slag (CS) is a nonferrous material by-product from the production of copper in metal form. The most common form found of copper slag is a dark color, a brittle stone that is presented in the most diverse sizes [1], which can vary in granulometry from a few centimeters to even powdery material [2].The vast majority of …

Copper Slag is by-product or waste stream from the production of copper. The smelting process produces a glass like substance that will settle on the top of the melting copper and is basically the non-copper impurities being separated. The slag is then skimmed off the melted copper and delivered to a "slag heap" or slag dump where it is left to cool.

Located in Hidalgo County, Playas was once a bustling "corporate town" built by the Phelps Dodge Corporation to house the workforce of a copper smelter built in 1971. The boom town was all but abandoned when copper prices fell in 1999, the smelter was closed, and most of its residents fled for better opportunities elsewhere.
1. Introduction. Slags are a left-over of the pyrometallurgical stages of recovery of non-ferrous metals from sulfide materials. Production of 1 t of copper results on average in formation of 2.2 t of slag; the annual global output of copper-smelting slags is ~ 25 Mt (Gorai et al., 2003).Due to the absence of an accepted efficient technology for …
Copper slag can be treated as a secondary resource since it usually contains a substantial amount of copper and other valuable metals. Characterization of the slags to determine the expected metal recovery is essential for the design of separation flow sheets. In...
The optimal CS content in HMA/WMA mixtures is typically found to be between 10 and 20% [13], [16], [17], [19], [20].The statements of Raposeiras et al.
