Abstract
The rate of dissolution in dilute acid is slower than malachite but faster than tenorite under the same conditions. These results suggest that heap leaching of chrysocolla in dilute acid may be slow relative to malachite but should present no chemical problems and that there is no advantage to be gained from the addition of chloride ions. High sulphate concentrations (100 g/L) in the raffinate solution to the heap could reduce the rate by up to one-half.
