Quality Phosphate Feed Supplements Start With Quality Ore
Lab technician Joe Johnson analyzes a sample in the lab at our phosphate plant in Aurora, North Carolina.
“It’s low in metallic impurities,” said Barrie Winn, Manager of Technical Services at Aurora. “So we start out with a high-quality ore, and that means high phosphate content.” It also means that it’s possible for us to refine that phosphate ore into a top-quality defluorinated phosphate, removing fluorine and ensuring the necessary levels of phosphorus and calcium. “The defluorination process is very sensitive to the quality of the rock that you use,” Winn said. “Competitors have trouble getting the quality of rock necessary to do this.” The phosphate mine, acquired by PotashCorp in 1995, has been active for 40 years — and it’s large enough to continue supplying the raw material for feed products for many more decades. “We still have a very long life here,” Winn said.
