Mineralogical-technological peculiarities of the ores of the Skrytoe Scheelite deposit and prospects for their dressing

This work presents the results of the study of a small technological sample taken from the borehole core drilled in the ore body of the Skrytoe deposit. Data on the mineral composition and the textural-structural features of the ores are reported. It was found that the studied ores are characterized by low concentrations of tungsten (WO3 less than 0.5%), high contents of phosphorus (P2O5 > 0.5%), and a content of sulfide minerals of no more than 10%. Based on these results, it was proposed to modify the available dressing scheme developed by the ZAO Mekhanobr-Inzhiniring company. This will permit one to optimize the efficiency of the scheelite extraction during mining.
