The document discusses spiral classifiers, which are used in mineral processing to separate ore slurries by particle size. It outlines several key variables that must be balanced for effective classification, including the angle of the inclined bed, speed of the rakes or spirals, slurry density, tonnage throughput, and ore settling rate.
