How to Effectively Extract Silver from Used XRay Films

Apr 13, 2021 2002. Q. Wish to know about the silver extraction method from waste hypo solution and the details about the machine and tools using the extraction. I am engaged in the business of silver extraction from the waste hypofixer and waste photo films. At present even though I am extracting silver successfully my procedure is very lengthy, risky and slow process.

Silver extraction from waste xrayhypofixer solution

Feb 01, 2011 Silver minerals are known to have slow leaching rates and low overall extraction and require a high concentration of cyanide and a long retention time to maximize leach extraction. Their response to cyanidation is considered mild to moderately refractory, largely due to complex mineralogical compositions. New research on improving the dissolution of silver minerals in cyanide was performed ...

Apr 01, 2016 Silver leaching from metallic scraps utilizing aqueous ozone, H 2 SO 4 0.1 M solution at an ambient temperature. The main by product O 2 was recycled to the O 3 generation or used as a leaching agent in a pretreatment step. In this leaching process, silver dissolved as Ag 2 aq in the range of 10 1 10 3 M H 2 SO 4 and the main reaction product Ag 2 O 2 was insoluble in pH 4.
