    CYQUEST® BGA positively impacts the rheological property of bauxite slurry by reducing the viscosity and stickiness during the grinding process. As a result, less energy is required and the specific energy consumption per ton of bauxite ground is reduced. This less viscous slurry is also easier to pump and again requires less energy.

  • 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.
