    Comparison of flotation performance between the flotation column and mechanical flotation was carried out to promote the grade and economic value of the graphite ore (15.40% ash content). The ash content of the concentrate of the mechanical flotation was 10.77% at the yield of 79.34%. In contrast, the yield of the concentrate of the column flotation was increased to 88.93% with 10.55% ash content.

    performance of column cells can be largely attributed to their unique geometry which readily accommodates the use of froth washing systems. This unique feature allows column cells to provide impressive levels of metallurgical performance closely approaching the ultimate separation curve predicted using flotation release analysis.
