to the geological origin of the phosphate. In parallel, beneficiation methods for phosphate rock are finite and include: comminution and size separation (crushing, grinding, attrition, screening and classification), mineral separation (flotation, gravity and magnetic separation)
This classification system splits out a +20 mesh pebble phosphate, a —20 +35 mesh fraction for agglomerate separation, and —35 mesh which is the feed to flotation. All classifier overflow and excess water accumulated in the washing steps are diverted back to the large primary hydroclassifier for retreatment.
The phosphate rock floating process is one phosphate rock grading forward-backward floating process, in which the raw ore pulp is first separated into two parts of different fineness and then forward-backward floated in two separated branches. The coarse ore pulp is made to separated in high concentration so as to save floating chemical; while the fine ore pulp is floated through …

The chemical name for the substance of quartz is silica; and any mineral that is composed in part of silica is a silicate. In the Classification of Silicate Minerals and the study of minerals and rocks, silica is called an acid; in silicates, the substances other than silica are called bases, for example, lime, potash, and soda. When giving the full name of a silicate the names …
Phosphate rock is fed into the front-end of a production plant and manipulated many times during its long process journey and eventual transformation into valuable end-products. This continual production process is central to efficient phosphate fertilizer manufacturing, with each process stage requiring specialized equipment.
