Phosphate Rock. The term phosphate rock or phosphorite is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world.
Rock phosphate is less subject to leaching. Using rock phosphate in its raw form helps to build the soil reserve, mitigates losses to surface and groundwater systems and reduces frequency of application. Eutrophication is a Major Environmental Concern caused by

Alibaba.com offers 197 uses phosphate rock products. About 66 of these are phosphate fertilizer, 1 are phosphate. A wide variety of uses phosphate rock options are available to you, such as quick, controlled, and slow.
soils such as limestone and rock phosphate exist but are unexploited. An experiment was conducted to assess the feasibility of using local Evate rock phosphate 40.7 total P 2 O 5 as a corrective to supply phosphorus. The rock phosphate was applied at rates of 20, 40, 80 and 160 kg total P ha-1. Comparison
2014-6-19In the present study, porous structure of raw and calcined phosphate ore particles was examined. The specific surface area and the pore volume were determined by nitrogen adsorption. Raw particles and calcined ores were leached using dilute phosphoric acid solution 4 P2O5. In all cases, the ESEM Environmental Scanning Electron Microscopy observations show that the grain of phosphate
As a mineral resource, phosphate rock is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.
