Abstract:

The gold leaching rate increased from 47% to 90% by the application of alkaline hot-Press oxidation of finely disseminated gold ore. The effects of amounts of alkali, temperature, partial pressure of oxygen, oxidation time et al. on the technology of alkaline hot-press oxidation were investigated.
