Some design considerations for spiral separators
Spiral separators have undergone continuous development over the past 40 years. The focus of some more recent developments has been towards the processing of progressively finer mineral particles. New model spiral separators have now been developed that are specifically designed to treat material finer than 0.1 mm.

Phosphate Rock Beneficiation Process
The phosphate ore processing can be divided into three stages: crushing—separation—concentrate dehydration. 1. Ore crushing process includes crushing, screening, grinding and grading processes. Use crushers and ball mills to reduce ore particle size to dissociate phosphorus minerals from impurity mineral monomers.
