Process Mineralogy Characteristics of Lokasi Beach Placer in Indonesia

Vanadium-titanium magnetite resources in China are mainly distributed in Panzhihua, Chengde and other areas. There few deposit belong beach placer type. In order to find out the washability of this type of vanadium titanium magnetite ore and provide a theoretical basis for its development and utilization. The process mineralogy characteristics of Lokasi beach placer in Indonesia were studied by chemical multi-element analysis, electron probe analysis, energy spectrum analysis and other methods. The raw ore grade of Fe is 26.03%，and the concentration of associated TiO2 and V2O5 are 5.56% and 0.22%，which meets the industrial grade standard of associated Ti and V for comprehensive recovery. The ore contains 25.59% titanomagnetite(hematite) and 3.87% ilmenite. Ore mineral grains with a narrow range of granularities and its distribution is concentrated. The liberation degree of titanomagnetite in the raw ore is more than 90%, 99% of the s titanomagnetite falls in the liberated class and mostly liberated class, The grinding cost is very low. Both titanomagnetite and ilmenite in this area are solid solution minerals with heterogeneous composition. Therefore, Ti content in ilmenite is lower than the theoretical value. At present, it is not possible to separating independent high grade titanium concentrate from Lokasi beach placer.
