Flotation recoveries in the twenty-four non-aged tests ranged from 0.63 to 11.8 percent with an average of 5.43 percent. Statistically, at the 95 percent confidence level all the recoveries may be considered equal at the average. In a similar flotation test on an unsulfidized sample the recovery was 4.31 percent.
