Heavy Minerals Florida Department of Environmental ...

After mining is complete the topsoil and overburden may be used in reclamation for slopes and revegetation. Heavy minerals occur as sand grains mixed with lighter clays and quartz sand grains. Within the ore body less than 5 percent of the grains may be heavy minerals. Two mining methods are used: suction dredging and auxiliary mining.

Mineral sand ores contain titanium bearing minerals of ilmenite rutile and leucoxene as well as the mineral zircon. They also contain trace quantities of the radioactive elements of uranium and thorium particularly monazite which is a mineral with reasonable thorium concentration 5-7.

Impact of silica mining on environment

Mining. sand falls by gravity to the bottom. After washing the sand is then sent to a surge pile where water adhering to the sand particles infiltrates back into the ground. From the surge pile the sand is sent to the dryer and screening operation where the sand is dried in a drum with hot air blasted into it.
