Diagnostic leaching is based on the concept that the least stable mineral in the ore matrix will be the first to be solubilized. The leach residue is cyanided to extract liberated gold and the process repeated using still higher oxidative acid leach until all the nonrefractory and refractory gold are liberated and cyanided [27–29].

Sulphuric acid digestion is the classical method which has been used for many years by the processing industry. The monazite leach solution produced through digestion with sulphuric acid contains REEs and others elements such as Th, U as well as phosphoric acid and excess sulphuric acid. The reaction of monazite and concentrated sulphuric


oxygenated acid solution and that covellite is the intermediate product. Gerlach and Pawlek (1968) studied the leaching of several sulfide min-erals in oxygenated sulfuric acid solution, and found that chalcocite leaches in two stages. Kuxmann and Biallab (1969) studied the electrode potential and elec-trolytic dissolution of chalcocite.

Apr 15, 2019· Secondly, acid leaching promotes the formation of crystalline SiO 2 (cristobalite, quartz). This crystalline SiO 2 has not been detected in non-leached samples (N40A, N30A, N20A and N10A), whereas it is detected in its acid-leached counterparts (H40A, H30A, H20A and H10A). This is most likely due to the removal of impurities by acid leaching ...
