Abstract

Abstract

In order to realize the comprehensive recovery of dolomite in the tailings after fluorite separation of Baiyun Ebo tailings, the tailings after fluorite roughing were used as flotation feed, the experiments were carried out in detail with DWZ-2 as collector and sodium silicate as depressant. The results showed thatthe dolomite content in the concentrate obtained by closed-circuit flotation with one-stage roughing and four-stage cleaning process was 83.62%, the recovery rate was 80.49%, the SiO₂ content was 0.86%, the removal rate of SiO₂ rate was 84.10%, and the whiteness was 45.7%. Modified dolomite may be a raw material for preparing dark rubber filler materials. This study is of great significance to improve the comprehensive utilization of dolomite resources, reduce the emission of tailings and improve the environment.
