<p>MINERAL SEPARATOR An apparatus is disclosed for gravity separation of comminuted solid particles. It has a transparent pipe (18) through which water flows upwards at a controlled velocity to float grains of a given size and specific gravity but to maintain lighter particles in a funnel on top of the pipe. The pipe is enclosed in a housing in which a water level can be raised or lowered to coincide with a mark on a scale indicative of the instant lowermost gravity of particles passing downwards through the pipe (18). The device is of a simple structure and provides the possibility of the readout of the specific weight of the accepted particles.</p> |
