Phosphate Rock Beneficiation Process
Its beneficiation process is designed to increase the grade (phosphorus content) and recovery of phosphate rock, thereby enabling efficient use of this resource. Scrubbing and desilting process is suitable for treating phosphate rock with high degree of weathering, but the grade and recovery rate of phosphorus concentrate are both low;

a Circular Journey from the Ground to the Recycling Line
The beneficiation of phosphate ore typically follows a dry crushing and screening operation where ore is prepared for the downstream wet beneficiation circuits. As will be discussed further in this paper, the use of dry sensor-based sorting has taken on new meaning with the drop in P 2 O 5 grades in the ground by helping to reduce waste …

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.
