Phosphate Rock

Manual of Fertilizer Processing, 2018
(Data in thousand metric tons unless otherwise noted) Domestic Production and Use: Phosphate rock ore was mined by 6 firms at 12 mines in 4 States, and upgraded to an estimated 30.9 million tons of marketable product valued at $3.5 billion, f.o.b.

Effective lead immobilization by phosphate rock solubilization mediated by phosphate rock amendment and phosphate solubilizing bacteria

Chemosphere, 2019
Lead can be immobilized in contaminated soils by phosphate rock (PR) amendment, but its efficiency is generally limited by low solubility of PR. Our study aimed to elucidate whether phosphate solubilizing bacteria (PSB) can promote Pb immobilization through PR solubilization. Results showed that P. ananatis HCR2 and B.

A Comprehensive Review on Occurrence and Processing of Phosphate Rock Based Resources- Focus on REEs

Mineral Processing and Extractive Metallurgy Review, 2023
In general, the phosphatic rock contains around 0.05 wt% rare earth elements (REEs). The global commercial phosphatic rock output is anticipated to obtain 250 million tons per year, making phosphate rocks a significant source of REEs.

Review on Mechanisms of Phosphate Solubilization in Rock Phosphate Fertilizer

Communications in Soil Science and Plant Analysis, 2022
Phosphorous (P) is an indispensable element for all life forms. Even though P is applied to the soil mostly in fertilizer, it has been found to be inefficient, because only a small portion of the applied P which is supplied is actually utilized by the ...

Uranium ions adsorption from acid leach liquor using acid cured phosphate rock: kinetic, equilibrium, and thermodynamic studies

Separation Science and Technology, 2020
The adsorption of uranium from acid leach liquor was studied in batch experiments using acid cured phosphate rock (ACPR). Different factors affecting the adsorption process such as pH, contact time, L/S ratio, initial uranium concentration, and ...

Phosphate rock bioleaching

Biotechnology Letters, 1992
Microbiological acid solutions produced byThiobacillus ferrooxidans andThiobacillus thiooxidans on pyritiferous concentrate were used to solubilize phosphate rock with a high grade in P2O5. Five different mixtures of pyritiferous concentrate and phosphate rock, in different proportions, were used in adequate liquid culture media.
