RE: RE: RE: RE: Amazon Mining drills 22 m of 2.6%according to the following article 5% of phosphate might be all that Amazon may be shooting for and which they achieved already in today's news:
Phosphate Concentrates
Besides the natural difficult characteristics for mining, processingand solubilization that apatites present, when compared to phosphorites,Brazilian igneous rocks have some additional unfavorable properties:very low P2O5 content in the run of mine(5% to 10%); high iron and aluminum oxides content; some accessoryminerals similar to the phosphate ore which prejudice the separationin the beneficiation processes.
Due to the peculiar characteristics of Brazilian rocks, it wasnecessary a huge effort to develop technology for processing andto produce concentrates comparable to those available in the internationalmarket. Leaded by Professor Paulo Abib Andery, the effort succeededand today Brazil is a leader in technology for processing lowgrade phosphate rocks. By using this technology, an extraordinaryincrease in phosphate production was reached.
The Brazilian production of phosphates started in 1943 by SerranaS.A. The mining and concentration of a residual ore with highP2O
