Flotation of Indium-beard Marmatite from Multi-metallic Ore
Flotation researches of indium-beard marmatite from the Dulong multi-metallic ore in the Yunnan Province of China has been studied in order to improve the grades and recoveries of zinc and indium of the zinc concentrate in the Dulong concentration plant. The experimental results have shown that copper sulfate mixed with a chemical reagent X-I as the activator in the marmatite flotation produced a much better beneficiation than copper sulfate alone, increasing the zinc and indium recoveries of 10% and 6%, respectively, while the concentrate grades were unchanged. Also, the new activator acted well around pH 10, allowing large savings on lime consumption in the marmatite flotation. In addition, it has been found that a sufficient activated time of activator with ore slurry in the flotation is needed to achieve good beneficiation of the marmatite ore.
