ABSTRACT:
Mineral separating apparatus comprises a hydraulic classifier provided with an exterior wall, an open bottom sorting column within said exterior wall, and means for introducing a swirl of hydraulic medium in the sorting column. The exterior wall provides a quiescent zone between the bottom of the sorting column and further has a spigot connected to the quiescent zone for discharge of refuse. A launder section is disposed above said exterior wall and sorting column and is in communication therewith. First and second weirs in said launder section are located on opposite sides, respectively, of said exterior wall. The first weir is higher than the second weir to provide a hydraulic flow gradient therebetween. A feed box in the launder section is separated from the exterior wall of the classifier by the first weir and a discharge spout for the launder section is located on the side opposite the second weir, whereby overflow of hydraulic medium from the first weir and sorting column passes over the second weir and out of said discharge spout.
Automatically controlled valve means is operatively associated with the spigot for maintaining the bed level in the quiescent zone at a predetermined height. Feed pulp mixed with water entering the feed box overflows the first and second weirs and also enters the region of the sorting column such that it undergoes conjoint stream and hydraulic classification before being discharged from the discharge spout.
