In Florida, the phosphate rock is sent to processing plants in which it undergoes "wet process" to convert it into phosphoric acid. In the process, sulfuric acid is added to the phosphate to create phosphoric acid — which is easily absorbed by plants. Phosphogypsum (or "gypsum"), a radioactive material, is a byproduct of this process.
The processing plant will have a throughput capacity of 2.9Mtpa and proposes to employ conventional flotation and magnetic separation processes. Ore from the mine will pass through a three-stage crushing (primary, secondary, and tertiary) circuit, with the tertiary unit operating in a closed circuit to produce a product size of -20mm.
