Mineral powder generally refers to the powder obtained after the mined ore is crushed and processed. For example, iron ore powder refers to the magnetic separation of different types of iron ore, such as limonite and magnetite. The iron ore with different iron content, the iron content of the mineral powder is 60-68%, the super concentrate powder is 70-72%, and the iron powder refers to the higher iron content than the ore powder, which is processed by different processing methods such as reduction method. , water or gas atomization method, mechanical pulverization method, electrolysis method, molten salt decomposition method, evaporative condensation method, etc., obtain high grade, and reach the granular iron powder of the required particle size.
