Industries

The high temperatures of steel, iron, cement, glass and ceramics production require thermal insulation in the form of refractory bricks using our DBM and EFM magnesia products. The agricultural sector uses our magnesia as a vital animal feed supplement and fertilizer to maintain plant and animal health. We support the path to net zero carbon emissions by supplying our magnesia to precipitate nickel and cobalt used in EV batteries. Our magnesia is also used in numerous industrial applications such as waste water treatment and the pulp and paper industry.
