Jan 10, 2012 However, the production of superphosphate and triple superphosphate involves procedures with potential emission problems which differ from those of phosphoric acid production. There is the potential loss of fluoride, primarily as calcium fluoride in the dusts from the primary grinding of phosphate rock, or from milling of the cured product.
Mar 23, 2018 Morocco remains the largest exporter of phosphate. However, the high cost of mining and threats of war has derailed the production of phosphate in the country. Chin is a distant second with 5% of the total reserves, translating to approximately 3.1 billion tons. However, China remains the largest producer of phosphate at 138 million metric tons.

Phosphate rock contained in an acidic slurry is ground by equipment wherein the acidic slurry contacts the metallic surfaces of the equipment. A method for monitoring and controlling grinding ball consumption is provided in which acid-neutralizing particulate iron contained in the acidic slurry is measured and correlated to control curves, which relate particulate iron concentration to slurry ...
FGF23 reduces serum Pi level by inhibiting both renal phosphate reabsorption and intestinal phosphate absorption via reduction of serum 1,25-dihydroxyvitamin D level. It has been unclear how the bone senses changes of serum Pi level and how the bone regulates the production of FGF23.

This work demonstrated a simple and green method for the synthesis of tin phosphate (SnP) catalysts for glucose to HMF transformation. In this process, SnP catalysts with various P/Sn mole ratios were prepared by solid-state grinding of a mixture of SnCl 4 5H 2 O and NaH 2 PO 4 2H 2 O at room temperature, followed by drying with or without calcination. . Physicochemical properties of the ...
