Recovering Cadmium & Tellurium from Scrap

While cadmium extraction improved with increased oxygen pressure, oxygen-pressure leaching could not match the extractions obtained with ferric chloride or hydrogen peroxide even at the highest pressures used. The highest cadmium extraction was 92.7% after 7 h of leaching under 400 psig O2. The leach residue contained 15.5% Cd. Leaching with ferric chloride or hydrogen peroxide yielded over 99 ...
