Features of Separation Process of Refractory Polymetallic Fluorite Ore for Fluorite Recovery

An analysis is made on the processing of two kinds of refractory polymetallic fluorite ores for fluorite recovery. It is found that reasonable adjustment of pH value of floatation slurry is of great importance to improving the quality of fluorite concertrates. In addition, the flowsheet structure and the content of heavy metal ions in the slurry have effects on the grade of fluorite concentrates as well.
