Hydraulic classification and tabling of ore ground to minus 20-mesh is used to concentrate the chromite. Reported mill results show an average concentrate grade of 38.5 percent Cr2O3 at a recovery of 86 percent. The chromite mineral, with an average analysis of less than 45 percent Cr2O3, limits the grade of concentrate to about 38.5 percent Cr2O3.
