J. Cent. South Univ. (2016) 23: 529-534 DOI: 10.1007/s11771-016-3099-8 Effect and mechanism of dolomite with different size fractions on hematite flotation using sodium oleate as collector LUO Xi... and Springer-Verlag Berlin Heidelberg 2016 Abstract: The effect of dolomite with different particle size fractions on hematite flotation was studied using sodium oleate as collector at pH of about 9......
chromium was recovered. The chromium-free aluminum residue(CFAR), after properly dispersed, was digested at 120-130 ℃ and more than 90% alumina can be recovered. And then the pregnant aluminate solution obtained from digestion was seeded to precipitate aluminum hydroxide. This new method can successfully recover both alumina and sodium chromate, and thus realize the comprehensive utilization......
