Rising levels of greenhouse gases (GHG) in our atmosphere make it necessary to find pathways to reduce the amount of GHG, especially emissions of CO2. One approach is carbon capture and utilization by mineralization (CCUM). With this technology, it is possible to bind CO2 chemically from exhaust gas streams in magnesium or calcium silicates. Stable products of this exothermic reaction are ...

Magnesite is usually leached in hydrometallurgical reactors using organic or inorganic acid or alkaline agents (Raza et al. 2015). There are several industrial methods to extract magnesium from magnesite, one of which is the Australia Magnesium (AM) process in which MgCl 2 and metallic magnesium are produced within HCl media (Demir et al. 2003).

Nonclay refractories are produced from a composition of alumina (< percent), mullite, chromite, magnesite, silica, silicon carbide, zircon, and other nonclays. Refractories are produced in two basic forms, formed objects, and unformed granulated or plastic compositions. The preformed products are called bricks and shapes.
