Investigation of the use of ammonium acetate as an alternative lixiviant in the leaching of malachite ore [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2013
The solutions containing ammonia allow for selective leaching of the copper from a copper ore. In this study, the leaching and kinetics of malachite ore were examined using ammonium acetate solutions as an alternative lixiviant.
