Mineral Processing and Extractive Metallurgy | 2018

Kinetics of malachite leaching in alkaline glycine solutions

B.C. Tanda; E.A. Oraby; J.J. Eksteen

Aqueous alkaline glycine solutions present technical advantages over acidic solutions for leaching oxidised copper minerals hosted in carbonate mineral matrix phases. In this study, the leaching an...
