Ball mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, ect.It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be …

The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2. Desilication

A ball mill is a commonly used crushing equipment, divided into cement ball mill, tubular ball mill, ultra-fine lamination mill, conical ball mill, ceramic ball mill, intermittent ball mill, overflow ball mill, lattice ball mill, wind discharge ball mill, double warehouse ball mill, energy-saving ball mill, and other types. 4. Grading

The main beneficiation methods of bauxite are washing, flotation, magnetic separation, chemical beneficiation, etc.The process of separating concentrates from bauxite ore is actually a process of removing gangue minerals and harmful impurities, and separating high-aluminum minerals and low-aluminum minerals to obtain concentrates …

This laboratory study investigates selective grinding and beneficiation options for a Greek bauxite ore. First, a series of batch grinding tests were carried out in order to investigate the grinding behavior of the ore and the effect of the material filling volume (fc) on the distribution of aluminium- and iron-containing phases. Then, the …
