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.
