| Abstract: | In a vanadium-titanium magnetite ore dressing tailings in Chengde, the TiO2 grade is only 2.60%, and the TFe grade is 7.73%. In view of the status of ilmenite resources in the tailings that have not been recovered and utilized, according to the tailings properties, this study adopts the pre-enrichment process of "magnetic weight combined with step grinding step separation". And the sulfuric acid, EM-B as adjusting agent, EM-3 as collector, after one roughing and one scavenging, five selected titanium flotation process, finally obtained the grade of TiO2 46.23%, the flotation recovery rate 83.25%, relatively 42.03% iron tailings recovery of ilmenite concentrate products, implements the comprehensive recycling utilization of tailings, provide reasonable resource utilization of such mines. |
