Research on the Flotation Process of Old Tailing in Burma

Abstract:

The test simple was taken from old tailing in Burma. The results of the chemical analysis and the phase analysis indicated that the grade of Lead was 2.84%, with the oxidation rate of 58.33% and the grade of zinc was 3.22%, with the oxidation rate of 16.56% in the old tailing. Through the research of the flotation separation test, the optimal grinding fineness (-0.044mm) was accounts for 73%. The optimum dosage of sodium sulfide was 1500g/t and the dosage of potassium dichromate was 600g/t. The separation effect of copper and lead was better, the ultimate concentration index: the grade of copper was 16.58% in the copper concentrate and the recovery was 56.18%. The grade of lead was 48.83% and the recovery was 96.67% in the lead concentrate.
