Identification and Description of Mineral Processing ...

To produce dry bauxite , most of the free moisture is removed by heating crude bauxite in rotary drying kilns. Calcined bauxite is produced by heating bauxite to reduce total volatile matter, including chemically combined water, to less than one percent. Approximately two tons of crude ore is required to produce one ton of calcined bauxite.

Understanding Particle Size Distribution Calculations HORIBA

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.
