Allen V. Barker, in Encyclopedia of Analytical Science (Third Edition), 2019 Rock phosphate. Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0-30-0, but the grade is noted as 0-3-0, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops.

Phosphate rock is a non-renewable resource that has taken 10-15 million years to form from seabed to soil via tectonic uplift and weathering. Many recent studies indicate that phosphorus demand could outstrip supply this century if no fundamental changes are made to the current trajectory, while others argue we have 'hundreds' of years ...

Avidin was covalently conjugated to the surface of calcium phosphate nanoparticles, coated with a thin silica shell and terminated by sulfhydryl groups (diameter of the solid core about 50 nm), with a bifunctional crosslinker connecting the amino groups of avidin to the sulfhydryl group on the nanoparticle surface.This led to a versatile nanoparticle system where all kinds of biotinylated (bio ...

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

Sulfuric acid is used as a key first step in the production of both MAP and DAP, after which it is mixed with phosphate rock to produce phosphoric acid. And since the phosphoric acid production process consumes energy, an on-site sulfuric acid plant – a net producer of energy – is a critical part of the fertilizer production process.

This work provides a brief economic evaluation of flameless phosphate rock calcination with CSP/HTRs as heat sources. The economic evaluation consists of cost comparisons against gas-fired kilns and economic feasibility calculations based on the net present value method. The flameless system with CSP/HTRs is currently not cost-competitive.
