摘要： Herein is disclosed a continuous process for manufacturing purified silver nitrate solutions comprising the steps of:a) transferring a crude silver nitrate solution, together with a slurry comprising silver oxide, to a multistage agitated reactor, thereby forming a mixture;b) maintaining a continuous weight percent undissolved solids inside the reactor such that silver oxide is 10 to 80 weight percent of said undissolved solids;c) transporting the first mixture through the reactor over a period of 15 minutes to 3 hours to form a reaction product; andd) filtering the reaction products through a continuous filter to form a silver nitrate filtrate.
