Abstract
A spiral trough separator having a vertical axis and adapted to separate fine particles from a liquid slurry stream of those particles flowing down the spiral trough. The trough has spaced groups of parallel grooves, transverse to the flow of the slurry, a drain adjacent the lower ends of the grooves for collecting concentrates or fines of the particles and a wash liquid outlet to deliver liquid into the slurry stream to remove impurities from such fines prior to collection in the drain. The wash liquid outlet is adjustable with respect to the wash liquid flow in the wash liquid trough of the spiral to select the appropriate volume of wash liquid to be introduced into the liquid slurry stream.
