Iron (Brasil, 2020). The main residue of iron and nickel mining is slag, a solid residue of low solubility and rich in magnesium silicate. The slag produced from iron and nickel mining at anglo american mining company's Barro Alto plant reaches 2.4 million tons per year. These residues are

Stabilization of Mine Waste Using Iron and Steel-Making

2015-8-16  1000 kg) of slag are produced in iron- and steelmaking in Japan each year. This slag is widely used for cement production, road construction, and as a concrete aggregate, but the capacity for use of recycled slags in these fields is saturated and new ways for using slag are required [6].

Slag: From By-product to Valuable Construction Material

Slag is composed primarily of silica and lime, with concentrations of other minor constituents, including alumina, magnesia, and other compounds. During the fluxing process, slag removes the non-ferrous constituents from the molten iron, which purifies the product.

African Journal of Microbiology Research

The main residue of iron and nickel mining is slag, a solid residue of low solubility and rich in magnesium silicate. A residue with potential use as a soil conditioner, however, it is still necessary to investigate whether its use brings impacts to the environment. Microorganisms are extremely sensitive to environmental changes, changes that can be used as environmental quality indicators.
