Heavy Minerals Florida Department of Environmental ...

Heavy minerals occur as sand grains mixed with lighter clays and quartz sand grains. Within the ore body, less than 5% of the grains may be heavy minerals. Two mining methods are used: suction dredging and auxiliary mining. Suction Dredging: An electrically powered suction dredge floats within a 15- to 20-acre man-made pond. The dredge
