  • Copper extraction

    Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals with the remainder of the ore being unwanted rock or gangue minerals typically silicate minerals or oxide minerals for which there is often no value.

  • Atmospheric alkaline preoxidation of refractory sulphide

    Four ironsulphidecontaining gold ores from the White Mountain mine in the Jilin Province China were studied to examine the benefits of using oxidative treatment prior to conventional cyanidation to leach gold. This pretreatment consisted of bubbling air into an ore/water mixture for eight hours while adding enough caustic sodium hydroxide to maintain a pH of 11 throughout the test. Three

  • Gold extraction

    A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes.
