How phosphate is mined and processed

Mining Sedimentary phosphate tends to be found in loose sediment, so it can be mined with dredge lines (or picks and shovels). In Florida, the phosphate is found mainly in one layer of clay and sand that's about 10-20 feet thick, and 15-50 feet below the surface. After the heavy equipment digs out the overburden (the sediment above the desired

Tailings.info Thickened Tailings Storage - A discussion

However, there are significant advantages to thickening tailings. Perhaps the most important is that higher volumes of water can be recovered and the seepage and evaporation losses from the tailings storage facility can therefore be minimised. Sustainable water use in the mining industry is becoming increasingly more important (Welch 2003).
