Investigation on Mineral Processing Technology of Ilmenite in Fengning,Hebei Province
Fengning ilmenite ore is a magnetic deposit in gabbro containing high phosphorus and low titanium,the main minerals in which are ilmenite,magnetite and apatite.The dissemination size of magnetite is so fine that even the percentage of-0.010mm level is up to 36.50%.The fine and vein magnetite are distributed in gangue and ilmenite,so the majority of the magnetite is difficult to be separated from the gangue.Ilmenite is difficult to be recovered by low-intensity magnetic separation even through fine grinding.In high-intensity magnetic separation of ilmenite,the gangue intergrowth with the magnetite and the Fe-containing silicates may be enriched in the concentrate,and the ilmenite of the concentrate will be reduced.Based on the processing mineralogy research,combined gravity-flotation process is suggested to recover the ilmenite.The method is also good to reduce phosphorus in the ilmenite concentrate.
