Recovering Aluminum from a Copper Leach Liquor by Ion Exchange, an Exploratory Study.
NTIS: PB 265 951 :22 pages
The federal Bureau of Mines investigated the potential for recovering aluminum from copper-dump leach liquors by use of single- contact ion-exchange technology. A strongly acidic ion-exchange resin was used to extract aluminum from a typical dump leach liquor and from synthetic leach liquors. Aluminum was stripped from resin with a h2so4 or nacl solution. Bench-scale experiments indicate that a single-contact ion exchange is technically feasible, but that the process is limited by the relatively low loading capacity of the resin and the excessive amount of stripping agent required. A further limitation is that significant amounts of magnesium and iron are loaded and stripped along with the aluminum.
