Abstract
A method of recovering a valuable component from a feed slurry in minerals processing plant for a mined material is disclosed. The method includes separating the feed slurry on the basis of particle size into at least two streams, of which one stream is a fines stream. The pH of the fines stream is then adjusted to be within a range in which contaminants on the surface of the fines are soluble so that contaminants dissolve from the surface of the fines. Thereafter, the valuable component is floated from the pH adjusted fines stream.
