Experimental Study on Flotation of Low-grade High-iron Bauxite in Western Guangxi
There is a high-iron-containing low-grade bauxite ore in West of Guangxi Province，with Al2O3 content of 44.40%，SiO2 4.51%，alumina-silica ratio only 3.06，and Fe2O3 22.43%. The main aluminum minerals in the ore are diaspore，and the main iron minerals are limonite and hematite. A view of the characteri...

| description | There is a high-iron-containing low-grade bauxite ore in West of Guangxi Province，with Al2O3 content of 44.40%，SiO2 4.51%，alumina-silica ratio only 3.06，and Fe2O3 22.43%. The main aluminum minerals in the ore are diaspore，and the main iron minerals are limonite and hematite. A view of the characteristics of low Al2O3 content, Al-Si ratio and high Fe2O3 content of the ore, the flotation results can be improved effectively by using of the combined depressants of sodium hexametaphosphates and sodium carbonate inhibition，as well as self-developed collector EM505 collecting agent. Aluminum concentrate with A/S ratio of 6.23 and Al2O3 recovery of 78.12% was obtained by the flotation closed-circuit test. This experiment has made breakthroughs in key technologies, providing a new method for the development and utilization of this difficult flotation of high-iron bauxite resource. |
