Extraction of lithium and aluminium from bauxite mine

Feb 15, 2021 The bauxite mine tailings used in this experiment were taken from Guiyang City, Guizhou Province. After crushing, reduction, grinding and sieving processes, samples less than 74 m in size were obtained. Samples were used for chemical composition analysis, mineral composition analysis and Al and Li extraction experiments. Learn More

Medium Characteristics on Selective Grinding of Low Grade

Selective grinding of bauxite with ratio of Al2O3/SiO2(A/S) 4.4 at ball mill were studied in order to investigate the effect of grinding media characteristics on selective grinding of bauxite. Results show that when diameter of ball media is Φ15mm, selective grinding effect is best and at this moment A/S of the product at -0.5+0.28mm granularity is up to 7.5. Learn More
