Production of Silver Metal Using the Patio Process. Preparing the silver for removal (step (a): The roasted copper and iron sulfides turn into copper sulfates (CuSO4) and iron sulfates (FeSO4). The salt (NaCl) reacts with the silver sulfide (Ag2S) in the open air and light to form silver chloride (AgCl): Ag2S + 2NaCl + 2O2 = Na2SO4 + 2AgCl.

The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, the froth stability ...
