Slags from smelting of copper concentrate contains from 2% to 20% of copper and are directed to slag cleaning operation carry out in electric furnaces or other slag cleaning reactors with injection of carboneous reductant. ...

The Chilean copper smelters are producing large amount of copper slags. These copper slags are deposited at landfills. In the present time, a huge amount of copper slags are accumulated in Chile. The main problem with ...

Samples of ASTM A-706 structural steel embedded in different concretes obtained from mixtures of alkali-activated steel slag and fly ash were exposed to accelerated carbonation under controlled conditions (4% CO2, 65% RH ...

Due to the production of industrial slags in massive amounts, there is a high demand for recycling these slags and avoiding their dumping in landfills. This article aims to recycle industrial slags in brick manufacturing ...

Steel slag is a powdery industrial residue that has CaO, MgO and SiO2 in its composition, which enables its use in agriculture for soil acidity correction. Most studies involving this residue have focused on understanding ...

To the benefit of gold minerals, extraction processes are generally applied by carrying out cyanidation and subsequent smelting to obtain dore thereby generating slags. The properties of the slag obtained vary depending ...

A primary lead smelter operating in Santo Amaro, Bahia, Brazil, from 1960 to 1993 generated a large amount of slag that was landfilled close to the former smelter and used in roads and houses as a construction material. ...

Alumina-magnesia-carbon (AMC) bricks are used in steelmaking ladles, where they are part of the bottom and sidewalls working linings. These refractories can be corroded by liquid slag, especially during tapping and casting. ...

During cooling and permanence outside, the solidified slag involved in the refinement process taking place in the steelmaking ladles suffers attack by environmental components such as water vapor and gaseous CO2 (weathering). ...
