Most ilmenite ore are poor ilmenite ore,so the ore benefication must be carried out. However, due to the majority of ilmenite is fine or micro- fine disseminated, and a considerable number of high phosphate, high iron and symbiotic beneficial metals, thus giving the beneficiation process has brought great difficulty. Ilmenite ore beneficiation methods currently used for the mechanical selection( including washing, screening, re-election, high intensity magnetic separation and flotation), as well as fire enrichment, chemical processing method. Ilmenite ore processing equipments and beneficiation methods analysis: 1. Washing and screening Use of the water to wash or rinse scrub additional mechanical separation of ore and mud. Commonly used the equipment are washing sieve, cylinder washing machines and trough washing machines. Ore washing operations often associated with screening , such as shaker directly flush cleaning or washing machine to obtain the ore ( net mine ) then sent the ore to vibrating sieve. Screening can operate independently, can make the separation of different particle size and grade of products for different purposes. 2 . Re-election To re-elect the current class structure is only used for simple, coarse-grained disseminated ilmenite, especially for larger density ilmenite. Commonly used methods of heavy media beneficiation, beneficiation and shaking jig beneficiation . Ilmenite mineral processing equipment currently handles the process of oxidation is generally broken ore to 6 ~ 0mm or 10 ~ 0mm, then grouped coarse level jig beneficiation, beneficiation of fine grade then send to the shaker. 3. Strong magnetic Ilmenite is a weakly magnetic minerals(the susceptibility X = 10x10-6 ~ 600x10-6cm3 / g), the magnetic field strength Ho = 800 ~ 1600kA / m (10000 ~ 20000oe) so the strong magnetic separator can be recovered, generally improve the grade of 4%~5%. Since magnetic separation, simple operation, easy to control, adaptability, can be used for a variety ilmenite ore sorting , and again in recent years, for the dominant mineral ilmenite processing, new types of coarse, medium and fine magnetic machine has been successfully developed. Medium-grained magnetic separator is currently the most common application for ilmenite ore beneficiation, but coarse-grained and fine-grained strong magnetic separator is gradually applied, micro- grained strong magnetic separator is still in the experimental stage.
