Processing - The Phosphate Risk

In Florida, after the phosphate rock is extracted, the ore is dumped into a pit at the mine site, and high-pressure water guns turn it into slurry. The slurry is pumped to a beneficiation plant. At the processing plant, the slurry mixture goes through a two-step process to separate the phosphate rock from sand and clay particles.
