  • Gravity Concentrationan overviewScienceDirect Topics

    Gravity concentration, or densitybased separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the selective treatment of lowgrade complex ores. They remain, however, the main concentrating methods for iron and tungsten ores and are used extensively for
