Copper slag, a by-product of the pyrometallurgical process used for obtaining copper from ore in Bor, Serbia, contains mainly silicon, iron, calcium, and aluminium oxides. Due to such properties, it is disposed landfills. Despite favourable technical properties slag aggregates possess, as low-water absorption (WA24 0.6%), low resistance fragmentation (LA 10%), wear (MDE 4%), its use constructio...

The industrial solid waste recycling team at North Minzu University has done much research on resource utilization of magnesium slag. This chapter mainly introduces a discussion includes the use slag to prepare glass ceramics, porous and sulfoaluminate cement clinker, fixing/stabilizing heavy metals in acidic residue generated by lead-zinc smelting, modifying copper

On the one hand, copper slag is nowadays a waste in pyrometallurgy despite significant quantities of iron (>40 wt. %) and (1 to 2 %). other solar energy, when properly concentrated, offers great potential high-temperature processes. Therefore, concentrated power (CSP) could be used treatment transform fayalite into magnetite sulfides oxides nodules. This objective this paper. The results sho...

This paper presents the research of the possibility to apply Artificial Neural Network (ANN) for solving nonlinear multivariate problems of the technological processes. After concurrent analysis facilitated using multivariate regression analysis (MRA) and ANN, on the same set of data, aiming to determinate the copper content in the waste slag depending on its chemical composition, following val...

A new twin-roll continuous slag solidification process and heat recovery process from a slag packed bed was developed for utilization of the waste heat of steelmaking slag. Plate-shaped slag with the thickness about 7 mm was successfully produced in a pilot plant, and the sensible heat of the slag was recovered by blowing air into the slag chamber. However, the gas distribution inside the slag ...

Clinker-free, carbonate-bonded monoliths are prepared by accelerated carbonation for immobilization of hazardous elements present in: a stainless-steel slag, two copper slags, and one lead slag. In addition to the studies on individual mixes slags with 33 % 66 replacements slag also studied. Combinations temperatures (30 60 °C) three CO2-pressures (1, 5, 10 barg) Among non-ferrous carbonated in...

Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted physical, chemical, and mineralogical characterization copper slag, along with preliminary tests. article focuses flotation, which two oneyear campaigns (2016 2017). The first campaign carried out using existing circuit plant. During second (2017), for sulfide o...
