Abstract

An apparatus for separating a mixture of heavy particulate material and light particulate material into separate fractions of heavy and light material is disclosed. The mixture is introduced to a first separating means, particularly an air jig, with a vibratory carrier for separating the mixture into a clean light fraction and a heavy fraction, which heavy fraction contains some light material. The heavy fraction is passed to a second separating means, this second separating means being a pneumatic table associated with the vibratory carrier for separating the said heavy fraction into a clean fraction of heavier particles and a mixture of lighter particles with some small heavier particles, which mixture is directed to a conveyor for recycling through the air jig. The apparatus provides for a very clean separation of heavy particulate material and light particulate material at a high throughput rate. PAC DESCRIPTION
