Phosphorite Wikipedia

Dec 01, 2004· Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that 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).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through

Using Rock Phosphate For Gardens What Does Rock

Sep 10, 2020· Rock phosphate, or phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize. In the past, rock phosphate was used alone as a fertilizer, but due to a lack in supply, as well as low concentration, most applied fertilizer is processed.

Nitrophosphate process Wikipedia

The nitrophosphate process (also known as the Odda process) was a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927.. The process involves acidifying phosphate rock with nitric acid to produce a mixture of phosphoric acid and calcium nitrate.. Ca 3 (PO 4) 2 + 6 HNO 3 + 12 H 2 O → 2 H 3 PO 4 + 3 Ca(NO 3) 2

Rock Dust Can It Remineralize the Earth? Garden Myths

Rock dust is also found near ancient volcanoes and consists of basalt rock. To be effective the rock needs to be ground into a very fine powder. That way it is more easily used by microorganisms and decomposed by environmental elements. Two common forms of rock, namely limestone and phosphate rock have been used for a long time to amend soil.
