(6) Elutriation separation of the product from chromite reduction at 1500 °C in the presence of SPL demonstrated its effectiveness in upgrading the ferrochrome alloy particles into a concentrate containing 53.0 wt.% Cr and 28.5 wt.% Fe, with a 68.4 wt.% recovery of Cr and Fe, while most slag components were effectively rejected.

Chromite Ore Processing. Low-grade ore obtained from an open cut trench at a chromite deposit near Auburn, Calif., was treated in the laboratory using gravity-magnetic separation and flotation beneficiation techniques. Flotation using known methods, however, gave very poor results and will not be discussed further in this report.

A less commonly used technique is elutriation, which represents an efficient, safe and low-cost method of separation. The goal of the present investigation was to make a comparative study of gold concentration by elutriation from different precious metal bearing ores: an oxide ore, a min-
