Enrichment
Process to increase the proportion of desirable material by the separation of the undesirable material.
Fractioning
Dedusting
A cleaning process in which dust and other fine impurities are removed. Dedusting can be accomplished both by pneumatic means and by dry screening.
Dewatering screen
A screen used for the separation of water from solids.
Dry screening
Screening of relatively dry material.
Drying
Drying is a process in which thermic energy vaporizes moisture mixed or bound in the product.
Fine screening
Screening of small grains. Fine screening is often carried out at the end of a process to produce the final products. Cf: screening.
