Flotation selectivity and upgrading of Woxna fine graphite

2001-11-1  In Flotation selectivity and upgrading of Woxna fine graphite concentrate 15 3 order to optimize the upgrading process, a three-step cleaning flotation circuit was employed after scrubbing for 45min, and to improve the flotation recovery of graphite, a

Flotation selectivity and upgrading of Woxna fine graphite

The present paper describes the effect of srubbing on the flotation selectivity of Woxna fine graphite concentrate and the upgrading process of the material. Results show that scrubbing in an attrition machine (with screened sand of −2.9+0.425 mm as attrition media) is an effective way to improve the flotation selectivity, and the material

[PDF] Comparison of mechanical flotation cell and cyclonic

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.
