Autogenous grinding and air classi- fication circuits have been used ex- tensively in iron-ore grinding prior to beneficiation. Semiautogenous grinding could be used in place of straight autogenous grinding. Dry grinding has lost favor in recent years to wet grinding of iron ore. A typical flow sheet is shown in Figure 12. CRUDE ORE SUPPLY. I
The flow sheet shown below illustrates a conventional closed circuit grinding operation. The cyclone overflow line is instrumented with a magnetic flow meter and nuclear density gauge, and the mass of dry ore fed to flotation is 2 0 t / h. The feed from the fine ore bins is sampled, and is found to contain 8 % moisture.

A thorough washing and some disintegration is given the ore by the trommel screen. The minus 2″ material passes to a cone or Forced Feed Jaw Crusher and is reduced to approximately minus ½". A Cross-Flow Classifier is used to dewater this minus ½"ore and also removes fine colloids. Classifier overflow is discarded. Lead Ore …

The presence of copper sulphides in the ore reacting with cyanide requires oxygen similar to gold, according to Elsners equation. If the ore has 7 ppm Au and 460 ppm copper then it is not hard to see the effect on the oxygen demand. Oxygen sparging will assist, however if the oxygen level drops then the leach kinetics will be affected.
Testwork was undertaken to develop a flowsheet that would maximise gold recovery from an ore containing 3 g/t Au and high levels of arsenic. Treatment of the sulphide ore …
The screen by-passes any material fine enough to enter the grinding section and delivers the oversize to a cone crusher, the discharge of which joins the undersize of the screen and is taken by a belt conveyor to the fine ore bin ahead of the grinding section. The fine ore bin can be designed to hold two days' supply of ore, but …
Ore sorting in mineral processing is separating the ore according to their size subsequent to the crushing and grinding of ore. For ore sorting in mineral processing, there are several methods. Depending on the mineral being processed, some may require more than one method before being determined ready for the next ore beneficiation process.
