Silver Recovery from X-ray Film Waste by Leaching and ...

The results showed that the NaOH and Na2S precipitants were able to recover silver optimally at a concentration of 1.5 M. The optimum leaching temperature of the film with the Na2S precipitant to recover silver was at 25oC, whereas in the NaOH precipitant the film leaching temperature only affected the time of precipitation. Therefore, the formation of precipitate using Na2S is more efficient than NaOH, but the acquisition of silver …

Refining of silver chloride to silver metal

Wash your Silver Chloride real good and put it in a container large enough for you to work in. Measure the water you use. Cover the Silver chloride with water to where you have about as much water over it as it is deep in the container. Then add 1/10th as much Sulfuric Acid as you have water. (400 ML of water = 40 ML of Sulfuric Acid.) Then just stir the Silver Chloride with something that is made out of iron. …

Fundamental aspects of thiosulfate leaching of silver ...

Silver recovery of the ground ore in batch leaching tests is low due to quartz locking of silver, with cupric-ammonia and ferric-EDTA leaches exposed to air recovering 31% and 26% after 24 hours, respectively. Cyanidation recovered 34% silver with a 95% confidence interval of 28-37%. The slightly lower recovery by thiosulfate may be due to silver minerals which are not amenable to thiosulfate ...
