Heavy Minerals

Heavy minerals can be concentrated from glacial till samples or from stream sediments. The theory behind the use of heavy mineral concentrates relies on the fact that by concentrating the heavy mineral fraction from the sample, the dilutant light minerals which may obscure an anomaly derived from a deposit are eliminated, providing a clearer picture.
