    OverviewPreferential flotationExamples of applicationClarification/thickeningSinking chamberTypes of gravity separators

    Heavy liquids such as tetrabromoethane can be used to separate ores from supporting rocks by preferential flotation. The rocks are crushed, and while sand, limestone, dolomite, and other types of rock material will float on TBE, ores such as sphalerite, galena and pyrite will sink.
