<p>A separator apparatus comprises a water tank 100 with a separation chamber, upper and lower water nozzles 110,111 and a weir 115. The water nozzles 110, 111 being positioned such that in use to separate material 150, they direct less dense particles 152 over the weir 115, whilst allowing more dense particles 151 to drop to the bottom of the separation chamber. Also disclosed is an apparatus as already described, further comprising a conveyor 172 to transport the denser particles 151 away. Also disclosed is a method consistent with the normal use of the first apparatus described. Further disclosed is a separator comprising an upwardly extending chute 100, a pump (125, fig.4) and a weir 115. The first/second apparatus and method maybe used for the floatation separation of the component parts of general builders rubble, containing such as plastics, cardboard, clipboard, to recycle elements of the rubble as hoggin, or low grade concrete filler.</p> |
