Rotary Dryers: The Ideal Choice in Processing Phosphates
Beneficiation of phosphate rock differs greatly from one deposit to the next, with common methods including screening, grinding, flotation, classification, filtration, and more. In general, however, they are all processed via a wet process, resulting in a wet phosphate rock, which must be dried before it can move on to subsequent processing.

Phosphate rock normally is used as a dry rock or in slurry form. However, in some cases, particularly where the raw phosphate is high in carbonaceous matter or it is desirable to have a clean acid, the rock is calcined. Also, in a few cases, the phosphate rock is calcined, the product slaked, and free lime separated as a beneficiation step.
