Mining and Exploration for Mineral Resources

2020-8-25 · Mineral resources have been formed by a variety of processes and in various places throughout the 4600 million year history of crustal development. The mineral deposits can, for convenience, be classified into three types based on their formative processes from magmatic to surface genesis, magmatic process, the process of solution-dominated

How phosphate is mined and processed

2014-4-21 · How phosphate is mined and processes 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.
