WO2014045301A2 - A process for preparing phosphates

The present disclosure provides a process for preparing phosphates from rock phosphate. Rock phosphate is powdered in a ball mill to fine powder with up to 75% of the powder having particle size less than 75 μm (microns) in diameter. Powdered rock phosphate is then reacted with an acidic reagent selected from the group consisting of sulfuric acid and phosphoric acid, under

What Is Involved in Phosphate Mining? (with pictures)

Next, the phosphate is extracted and purified. Few phosphate deposits are pure enough for the separation process to be eliminated. The specific process used to separate phosphate from other minerals varies based on the exact composition of the ore. In most cases, however, water is used to turn the rock into mineral slurry, from which a combination of screening and filtering
