Such a technology is always considered if it is possible to isolate concentrate (sinter ore) from finely crushed rich iron ore using DMS. The feed at the last grinding stage of magnetite ores beneficiation circuits contains a significant amount of open grains of magnetite (titanomagnetite).
The process of mining and beneficiation to produce one ton of commercial rock phosphate (32 % P2O5) requires approximately 0.9 GJ/tonne rock or 2.9 GJ/tonne P2O5. If the rock is calcined the total energy requirement is doubled (Ullmann, vol. A 19, 1991). References: BAT N° 4 (1995).
11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.
