Phosphate Rock - an overview | ScienceDirect Topics
Phosphate fertilizers are prepared by beneficiation of phosphate rock to remove its impurities, followed by drying and grinding. The PO 4 in the rock may then be reacted with sulfuric acid to produce normal superphosphate fertilizer.
11.21 Phosphate Rock Processing
The major emission sources for phosphate rock processing are dryers, calciners, and grinders. These sources emit particulate matter (PM) in the form of fine rock dust and sulfur dioxide (SO2). Beneficiation has no significant emission potential because the operations involve slurries of rock and water.

how to remove sio2 from rock phosphate by grinding
Grinding of phosphate rock to fine powder has following advantages Increase the rate of reaction Less sulfuric acid is needed A higher grade of product in better condition is obtained. A finely ground (less than 100 meshes) phosphate rock is mixed with sulfuric acid in a cone mixer. The commercial concentrated sulfuric acid (77 to 98 %) is
Phosphate Flotation - Mineral Processing & Metallurgy
Phosphate GRINDING. Wet rod mill grinding to approximately 35-mesh is employed as only a moderate degree of grinding is required and the production of slimes must be minimized to effect maximum recovery. The Rod Mill operating in closed circuit with a Cyclone Classifier is effective in accomplishing the liberation of the phosphate minerals.
