The Metallurgy of Cyanide Gold Leaching – An Introduction. Leach Kinetics: The pH and the temperature of the reaction can affect the kinetics of the gold dissolution reaction. However the pH and temperature will also affect the kinetics of other deleterious reactions (like those outlined above), and determining the correct conditions for the leach can substantially affect the overall performance.

For the production of pure chromium, the iron must be separated from the chromium in a two step roasting and leaching process. The chromite ore is heated with a mixture of calcium carbonate and sodium carbonate in the presence of air. The chromium is oxidized to the hexavalent form, while the iron forms the stable Fe 2 O 3.
