Specifically describe the beneficiation method of utilizing ilmenite to choose ilmenite concentrate of the present invention below in conjunction with exemplary embodiment.
First, ilmenite is carried out to magnetic separation, to obtain nonmagnetic the first material.Specifically, ilmenite is a kind of low intensity magnetic separation mineral, therefore, need to pass through high intensity magnetic separation (that is, magnetic field intensity is greater than 5000Gs) and remove the iron in ilmenite, to obtain the having nonmagnetic raw material of choosing ilmenite concentrate.
According to exemplary embodiment of the present invention, before magnetic separation, can carry out gravity treatment to ilmenite.Because ilmenite proportion is greater than gangue mineral, therefore, can do pretreatment by gravity treatment to ilmenite or roughly select throwing tail, to reduce the content of gangue in ilmenite.
Then, the first material is sent into grinding machine (for example, ball mill) and carry out ore grinding processing, to obtain through ore grinding the second material after treatment.Specifically, before ilmenite is sorted, for ilmenite and gangue are dissociated, need to carry out ore grinding to ilmenite, to promote the abundant monomer dissociation of ilmenite, improve the rate of recovery of ilmenite concentrate.

the second material～500kg/t
the second material, preferably, in the second material, granularity is that-120～+ 200 object particles can be 600kg/t
the second material, granularity is that-200 object particles can be 400kg/t
the second material, this granularmetric composition can be dissociated ilmenite and gangue fully, can also avoid occurring because the second material overground causes the situation about increasing that sorts difficulty and sort cost of the ilmenite concentrate that mineral argillization causes.
Secondly, the second material is sized mixing, to obtain 3 material.Specifically, utilizing ilmenite flotation ilmenite concentrate is to carry out in ore pulp, therefore needs to the processing of sizing mixing as the second material of flotation feed, to obtain having the 3 material of certain solids content.
