Strong magnetic iron ore beneficiation process

It is mainly used to select low-grade magnetite. Due to the strong magnetic properties of the ore and good grinding, the current stage of grinding is used for the coarse-grained magnetite. Otherwise, the multi-stage grinding process is adopted. Currently, Ludong The promotion of fine grinding technology can increase the concentrate grade from 61% to about 67%.

Weak magnetic iron ore beneficiation process

Weak magnetic minerals can be sorted by strong magnetic minerals after magnetization roasting.

fine grinding

In the two-stage grinding, stage selection, and single weak magnetic separation process, the re-grinding and re-selection process on the fine sieve is added, which can separate the fine-grained minerals that have dissociated from the monomer in time, and reduce the occurrence of over-grinding. Improve the processing capacity of the ball mill and increase the concentrate grade by about 2%.
