Processing of Magnetite Iron Ores Comparing Grinding

Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.

Magnetite LKAB Minerals

Our customers are using our natural iron oxide mineral because it can store heat very well. They are mixing our Magnetite for over 30 years in heat blocks in Night Storage Heaters. If you look for a larger storage opportunity for thermal heat, Magnetite is a sustainable solution. Facts about our natural mineral that confirm its potential for upscaling heat stMagnetite Grades For Use in Foundry ApplicationsLive Chat

magnetite deposits to also be developed. There is a rich and long history of magnetite ore processing in Western countries, including large operations such as Cleveland Cliffs in the USA and LKAB in Sweden, as well as smaller operations like Savage River in Tasmania. The challenge for virtually all magnetite operations is to minimise operating
