PROCESS FOR THE SOLUTION OF METALS INTO AN ELECTROLYTIC DEPOSITION SOLUTION AND SOLUTION PLANT OPERATING SUCH PROCESS

摘要

A process for dissolving metals, in particular tin, and a plant for dissolving metals (50) operating according to said process allow to minimize the quantity of metal in the sludge and the oxygen consumption, and entail a first step in which in a first reactor (51) an effective quantity of oxygen is solubilized in an electrolytic solution obtaining an oxygen-enriched electrolytic solution; and a second step, distinct from the former, in which in a second reactor (52) said oxygen-enriched solution is flown through a bed of metal for the deposition in a metallic form.
