Abstract Combining the effective actions of vanning, tabling and heavy mineral pan-ning, a new type slime coneentrator, so called "the vibrating-shaking vanner",has been developed. This concentrator is characterized by concentration ofheavy mineral grains in sub-sieve range. Its remarkable performance is of higherrecovery, as well as of higher ratio of concentration. The lower limit of thegrain size which can be effectively concentrated is about twenty microns. In thecase of concentrating the slime of tungsten, tin or niobium-tantalum ores, com-parative tests on the vibrating-shaking vanner against common table and vannergenerally gave better results, especially for grain size down to forty microns.Furthermore, this vanner can also be applied for table-flotation of slime concen-trates in order to separate sulphides or to recover heavy minerals from flotationconcentrates contaminating with sulphides. Long-time service has proved that theabove vanner gives good performance and its application in metallurgical industryis ever-increasing.
