Normal superphosphates are prepared by reacting ground phosphate rock with 65 to 75 percent sulfuric acid. An important factor in the production of normal superphosphates is the amount of iron and aluminium in the phosphate rock. Aluminium (as Al 2 O 3) and iron (as Fe 2 O 3) above five percent imparts an extreme stickiness to the ...

Jun 12, 2015 By 1880 more than sixteen hundred men mined the land, which paid well (about $1.75 per day) but was grueling work. Ankle-deep in mud and under the hot sun, freedmen with shovels and picks excavated several feet of overburden before reaching the twelve-inch phosphate layer. Miners pushed the rock in trams toward the river, where others dried the ...

The quality of phosphate rock is generally identified by its content of tricalcium phosphate (Ca3P2O8), called bone phosphate of lime (BPL). Chemical analyses are usually reported as the P2O5 percent (phosphoric acid) or percent of BPL (1% BPL 0.485% P2O5). Phosphate Rock Lime Ball Mill.

type of rock being used. This, in turn, influences mill selection. For an igneous phosphate rock, for example, single super - phosphate (SSP) production require a feed with 90 percent passing 53 microns. This falls to 90 percent passing 75 microns when sedimentary phosphate is con-sumed. When it comes to phosphoric

Phosphate is a key component in sustaining healthy and productive crops. While most phosphate rock goes to the production of MAP and DAP fertilizers, this life-giving mineral can be made into a variety of fertilizer products and blends through the process of granulation. FEECO has been a leader in the fertilizer industry since 1951.
Phosphate rock is a kind of ore with good grindability. Therefore, the grinding process of phosphate rock usually adopts one-stage closed-circuit grinding process or two-stage one-closed circuit grinding process. The grinding equipment used is usually a ball mill.
