elution gold selective

Elution and electrowinning of gold from gold-selective ...
1995-4-1 · Partially gold-selective resins are used and, from the literature available [ 7 ] , it appears that the thiourea elution procedure is preferred. As explained above, they use a sequential selective elution procedure to avoid resin poisoning, which can occur in the acidic medium. Unfortunately, no operating data or costs are available.

Elution and electrowinning of gold from gold-selective ...
The recovery of gold was investigated using the new gold-selective resin, Minix, which was developed by Mintek. The most suitable elution technique for this resin was found to be an acidic thiourea eluant. The gold-selective adsorption characteristics of Minix, particularly its high selectivity against cobalt and iron cyanides, make it possible ...
