Mining 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.

Sand and Gravel Mining Industry Additional Information

Sand and Gravel Mining Industry. When rocks erode out of the Rocky Mountains and are carried downstream by streams and rivers, they break apart making sand and gravel. The sand and gravel settles out of the water and form the river bed. As the river channel moves across the landscape, the sand and gravel (aggregate) deposits are left behind.
