  • Method for sorting a collection of bodies comprising cemented carbide bodies and non-cemented carbide bodies
    Patent number: 9770720
    Abstract: The disclosure relates to a method for sorting a collection of bodies including cemented carbide bodies and non-cemented carbide bodies. A melt having one or more of bismuth, tin and lead and having a density in the range of 7.0-12.0 g/cm3 is provided. The collection is subjected to a sorting process based on density difference by providing the collection in the melt and allowing the bodies to be sorted into a first group at a top surface of the melt and a second group at a bottom of the melt. The first group includes non-cemented carbide bodies having a density lower than the density of the melt and the second group includes cemented carbide bodies having a density higher than the density of the melt.
