6. Separation and concentration. Following milling, the ore is subjected to different processes according to its nature. Pulp may require to be thickened ahead of these processes in large tanks called Thickeners, in which the solid component is allowed to settle and is raked towards the centre by large, rotating rakes while relatively clear water overflows into a peripheral drain or Launder.
