Kinetics of Leaching Native Copper Ores With Dilute Ammonium Carbonate Solutions.
NTIS: PB 266 798 Available for Reference At Bureau Libraries :95 pages
Kinetic studies of the dissolution of small-diameter copper wires immersed in ammonium carbonate solutions are described in this report. The rate is shown to be proportional to the concentration of cupric ion at the metal-solution interface. The studies showed that, although dilute solutions have a higher cupric ion efficiency, they exhibit a lower rate of leaching and a greater tendency to precipitate cu2o. These studies may be useful in determining optimum conditions for leaching native copper ore.
