Silver Recove with !on Exchan e and Electrowinning

ppm silver, there are periods where the silver concentration is much lower. A rinsewater sample was diluted to 1.6 ppm and run through a thiocyanate-regenerated column of resin. The result of this test is show in Figure 3. It is important to note that as the influent concentration is reduced, the silver leakage in the effluent is also reduced.
