Processing
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.

Radioactive Material From Fertilizer Production | US EPA
When processing phosphate rock to make fertilizer, the phosphorous is removed by dissolving the rock in an acidic solution. The waste that is left behind is called phosphogypsum. Most of the naturally-occurring uranium found in phosphate rock ends up in the acid and the other radionuclides, including radium, mostly end up in the waste.
