Learn MoreThe extraction of silver from the treatment solution by nitric acid precipitation of silver sulfide is insignificantly affected by the strength of nitric acid used. Between 2 to 8 molar concentration for nitric acid in a pulp density of 100 to 200 g/l of solids demonstrated, as shown in the following Table 7, that satisfactory recovery of silver can be achieved.
Learn More· Put the silver into one of the five-gallon buckets, then measure out and pour the appropriate amount of nitric acid onto the silver as specified by the weight. The silver will react violently to the acid, and will up and bubble for several minutes as it is dissolved, so ensure that the bucket is only about 1/3 full of metal before pouring the acid.
