Limonite is an important iron-containing mineral, the main component is iron oxide, the surface seems to be brown, limonite without beneficiation processing has low application value, because natural limonite is mixed with many impurities, so to improve the application value of limonite, first of all, you have to be beneficiation processing, limonite beneficiation to follow the following steps:

1, coarse crushing + fine crushing

Limonite first through the jaw crusher for the initial crushing, crushing to a qualified size, and then sent to the fine crusher for fine crushing, jaw crusher is coarse crushing of limonite, after coarse crushing of limonite material size is greatly reduced, the shape is also more regular, fine crusher is mainly on the limonite material for the crushing again, at this time the limonite material size is finer.

2、Grinding, secondary crushing

Ball mill is the core equipment in limonite ore dressing process, the limonite particles that meet the size requirements are fed into the ball mill by the feeder to be ground until the limonite particle size meets the production requirements of the next process.

3、Washing and grading

The main function of spiral classifier is to wash and classify limonite, the principle of spiral classifier is that solid particles with different specific gravity will have different settling speed in liquid.

4、Adding chemicals for flotation

Add the corresponding chemicals in the slurry, carry out flotation operation, so that the required substances and other minerals to realize the separation, improve the purity of limonite, that is, to obtain high-grade limonite concentrate.
