Sometimes the most effective procedure was to float ore without desliming. For ores with Cr2O3 content less than 15 pct, high recoveries along with high grade were generally not achieved. Magnetic and electrostatic separation methods were less effective than tabling or flotation as primary beneficiation procedures.
