Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process.

1. Introduction. Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of environmentally harmful dust and gases during the production process [1], [2], [3].The two primary raw materials for pellet production are hematite and magnetite concentrates.
For high-grade magnetite, a closed circuit is usually used to obtain magnetite ore with qualified size; For low-grade magnetite, three-stage open-circuit or three-stage closed-circuit operations are used to complete ore crushing.
Once extracted, magnetite undergoes a series of crushing and grinding operations to reduce its size and liberate the valuable mineral particles. Primary Crushing: Taming the Ore's Coarseness. The initial stage of crushing involves breaking down large magnetite rocks into smaller pieces using jaw crushers or gyratory crushers.
Iron ore beneficiation is mainly a process of separating valuable minerals and iron minerals from ores to extract high-quality iron ore. The iron ore process mainly includes crushing, grinding, washing, beneficiation, dewatering, etc. 1. Magnetite Beneficiation: The main iron mineral contained in magnetite is iron tetroxide (Fe3O4).
