Phosphate Beneficiation Process
Large scale mining and processing of phosphate is essential for operating at a profit. In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the …

Processing - The Phosphate Risk
At the processing plant, the slurry mixture goes through a two-step process to separate the phosphate rock from sand and clay particles. The first stage is a concentrating process that separates the phosphate pebbles from everything else. The average operation can wash and size a maximum of 375 tons of pebbles in an hour.
The Mining Process - Welcome - The Phosphate Risk
In Florida, the phosphate rock is extracted by a process referred to as strip-mining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 30-40 feet below ground. Sandy topsoil, also known as overburden, is removed by large digging machines called draglines.
