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.

Grindability characteristics of lateritic and karst ...

Research highlights Grindability characteristic of five different kinds of bauxite was investigated. Temperature and alkaline media have significant effect on the grindability. Possible reasons of the Bond work index decrease were revealed. The grinding work of bauxite should be divided by an empirical adjustment factor. The factor strongly depends on texture and type of bauxite being tested.
