Beneficiation of vanadium-bearing magnetite from the Sinarsuk Deposit, West Greenland

摘要

Vanadium mineralization occurs in oxide-rich horizons within layered metagabbro zones of the Sinarsuk deposit, West Greenland. The main oxide minerals are vanadiferous magnetite and ilmenite, comprising 30% to ～90% of the rock volume and the ratio of magnetite to ilmenite ranges from ～3:2 to ～4:1. Magnetite and ilmenite have vanadium concentrations ranging from 1.93 to 2.68 wt.%, and 0.32 to 0.59 wt.%, respectively, equivalent V_2O_5. Preliminary beneficiation of two composite bulk samples shows the samples can be beneficiated fairly easily using low-intensity magnetic separation at a coarse grind (106 to 600 microns) to yield a vanadiferous magnetite concentrate.
