beneficiation of phosphate rock processing :

11.21 Phosphate Rock Processing - US EPA

2015-9-10  Phosphate rock from the mines is first sent to beneficiation units to separate sand and clay andto remove impurities. Steps used in beneficiation depend on the type of rock. A typical beneficiationunit for separating phosphate rock mined in Florida begins with wet screening to separate pebble rockthat is larger than 1.43 millimeters (mm) (0.056 inch [in.]) or 14 mesh, and smaller than 6.35 mm(0.25 in.) from the balance of the rock. The pebble rock is shipped as pebble product. The materialthat is larger than 0.85 mm (0.033 in.), or 20 mesh, and smaller than 14 mesh is separated usinghydrocyclones and finer mesh screens and is added to the pebble product. The fraction smaller than20 mesh is treated by 2-stage flotation. The flotation process

1992-1-1  In the beneficiation of Florida phosphate rock, flotation plays a predominant role because it is the most economical way to separate the phosphate values from the sand and other impurities contained in the matrix. Typically, the matrix is washed and deslimed at 150 mesh. The material finer than 150 mesh is pumped to clay settling ponds.

Phosphate Rock Beneficiation

2019-1-20  Florida phosphate occurs in a sand-clay matrix overlaid by unconsolidated overburden of sand and sandy clays, ranging from 10 feet to 45 feet in depth. The matrix usually occurs in fairly horizontal and continuous beds ranging from 3 feet to 25 feet in thickness, and is composed of clay minerals from the montmorillonite family, silica sand, and phosphate particles from ¾” to 200 mesh.

How phosphate is mined and processed

2014-4-21  rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
