The first parameter investigated was the amount of SO2 required per ton of ore for maximum silver extraction. Sulfurous acid was used as a source of SO2 for these initial experiments. The data in figure 4 show that silver extraction increased rapidly up to a maximum of 85 percent with increased additions of H2SO3 and then remained constant.

Silver ores exist also, mainly I know "cerargirite", "argirite" and "argentite", e.g. respectively AgCl, Ag2O and Ag2S. The latter is the MOST STABLE SILVER'S COMPOUND, thus it is the most important silver's ore. Instead argentite, silver's oxides are easily converted in metalic silver by means of a simple heating process.
