A method for dewatering phosphate slimes and recovering a liquid solution involves adding a calcium sulfate hemihydrate to the slimes, mixing the resulting admixture to effect formation of calcium sulfate dihydrate crystals in the admixture, and recovering a liqwd .
The sand is saved for reclamation and the phosphate is dewatered and stored in stockpiles. The stored phosphate rock is shipped by rail to the processing plant where it is finely ground to a uniform size and mixed with Sulfuric Acid. The result is Calcium Sulfate and Phosphoric Acid.

Abstract. Phosphate clay wastes, as currently produced, leave montmorillonite clay in a highly dispersed and disintegrated form. Alternative processing, where the extent of swelling and selfdisintegration of such clays is controlled or limited, may result in improved settling and consolidation behavior.

122 PHOSPHATE ROCK (Data in thousand metric tons unless otherwise noted) Domestic Production and Use: In 2018, phosphate rock ore was mined by five firms at 10 mines in four States and processed into an estimated 27 million tons of marketable product, valued at billion, free on board () mine.
Mining and Beneficiation: Another research focus in the beneficiation area is to streamline the flotation process and reduce the number or amount of reagents (chemicals) used to separate the sand and clay from the phosphate rock after it is mined. The Institute is also looking for ways to use computerized technology to control the beneficiation process.
Efficient phosphate production requires a complex sequence of interconnected processing operations – each stage of the process affects the next. For example, inefficiencies in mining can adversely affect phosphoric acid production and ultimately impact fertilizer quality.
Step1: The phosphate rock is digested with sulfuric acid (rarely HCl also may be used) Step2: 'PA' generated is separated from resultant CaSO4 slurry by filtration. To generate filterable slurry and to enhance the P2O5 content, much of the acid filtrate is recycled to the reactor. The two filtration processes are as follows: 1.

of phosphate rock mining and processing has occurred at numerous sites around the world over the past few decades. Vertical integration of phosphate rock mining and processing may be a necessary component to compete in the world phosphate fertilizer market when new deposits are developed.
Electrokinetic dewatering of a phosphate clay was investigated in an experimental program. The results show that the velocity of sedimentation is controlled by the applied current density and that electroosmotic permeability dominates the effectiveness of electrokinetic consolidation.

Phosphate Rock. Phosphate Rock is an excellent natural source of phosphorus, calcium and many essential trace elements. It contains over 30 percent total phosphate (38 percent available) and 48 percent calcium (as CaO). Phosphate rock has approximately one fifth the neutralizing power of lime.
Hard rock mining along the rock phosphate ridge is now a memory accessible by historical museums in each of the towns of the phosphate ridge. Still today, 80% of all phosphate used in the and 25% used in the world's supply is mined from deposits found in other locations in Florida.

Phosphorite, phosphate rock or rock phosphate is a nondetrital sedimentary rock which contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4%  to 20% phosphorus pentoxide (P 2 O 5 ).
