The ore properties and strengthen separation of bauxite were studied in this paper. The parameters in strengthen separation, such as dosage of collectors, flotation turbulence and inflation etc., were also discussed. With the increase of collector dosage, the recovery of Al2O3 increased.,When the collector dosage was 900 g/t, A/S of foam was 7.06 and the recovery was 86.39%.
Abstract. The existence of sulfur and silica in bauxite influence the product quality of Bayer alumina. The synchronous desulfurization and desilication of low-grade and high-sulfur bauxite through reverse flotation processes were studied using modified starch as depressants in this work.
1. Used for Bauxite flotation-In the process of bauxite flotation and separation of silicon, such as , aluminum silicon ore and arsenic containing silicon ore. 2. Resistance for acid and alkali,the removal rate of silicon can be achieved under neutral condition, and the removal rate is above 95%. 3.
Bauxite flotation process separation of silica from bauxite via froth flotation this flotation was carried out in two steps the first step was the flotation of gibbsitekaolinite from quartz at ph 2 using alkyl sulfates as collectors the second step was the flotation of kaolinite from gibbsite using amines at ph 8.
Flotation desulfurization [11] can remove the sulfur from the bauxite before entering the alumina refining process and negatively impacting the efficiency and economics of producing alumina from high-sulfur bauxite. Pyrite is the main sulfide mineral in high-sulfur bauxite [12], which is easily floated by
The existence of pyrite results in high soda consumption, iron pollution of alumina oxide and pipeline corrosion in the utilization of high-sulfur bauxite during the production of Bayer alumina. The flotation desulfurization of high-sulfur diasporic bauxite with modified 2-mercaptobenzimidazole (MBI) collector was studied in this work.
