Phosphate rock and Phosphorite, calcined Usage And Synthesis
Definition
Substance obtained by heating naturally occurring phosphate rock to 732.degree.C to 816.degree.C (1350.degree.F to 1500.degree.F) in a fluidized bed or other suitable device for oxidizing carbonaceous matter. Characterized by upgraded phosphorus content and reduced hydrocarbon levels.
Agricultural Uses
Phosphorite or mineral phosphate is made by grinding
rock phosphate, a natural mineral found in the form of
sedimentary rocks containing various calcium phosphates.
It is used as a phosphatic fertilizer, and is a primary
source of phosphorus. It is a mineral containing calcium
phosphate with hydroxyl groups or is hydroxy apatite.
Phosphorite is a continental phosphatic rock,
consisting of concretions of collophanite, found in
decalcification clays. The most famous phosphorites are
from Causses du Quercy (France).
