摘要： The invention proposes a process for producing electrolytic lead and elemental sulfur from galena, characterized in that it comprises the following steps:
(a) Galena is leached with an acidic aqueous solution of ferric fluoborate, with ferrous fluoborate, lead fluoborate and elemental sulfur being formed according to the reaction:
2 Fe(BF₄)₃ + PbS → 2 Fe(BF₄)₂ + Pb(BF₄)₂ + S (b) the solid residue, composed by elemental sulfur and galena gangue is filtered off; (c) the solution of ferrous fluoborate and lead fluoborate coming from the (a) step is sent to a diaphragm electolytic cell, wherein pure lead is deposited at the cathode and at the anode ferrous ion is oxidated to ferric ion; (d) the solution of ferric fluoborate regenerated at the anode in said (c) step is recycled to said (a) step of galena leaching. By operating under suitable conditions, lead can be selectively dissolved and separated from the other metals small amounts of which are contained in galena together with said lead. Sulfur produced by the reaction can be separated from the gangue by extraction with a solvent, or by flotation.

摘要： The raw lead to be refined, whether of mineral origin or from reclaiming operations, the particle size of which has been reduced to a range not larger than 50 mm, is leached in a suitable apparatus with a solution of ferric fluoroborate in fluoroboric acid.
During the leaching step, lead gets dissolved, with ferric fluoroborate being reduced to ferrous fluoroborate according to the following reaction:

2 Fe (BF₄)₃ + Pb ---> Pb(BF₄)₂ + 2Fe(BF₄) (1)

The leaching apparatus behaves hence as an external anode installed outside of the cell.
The resulting solution is sent to the cathodic compartment of a diaphragm cell in which lead is deposited on a cathode of stainless steel, in compact, highly pure form, from which it is periodically won.
The so depleted-of-lead solution is sent to the anodic compartment of the same cell, in which a suitable anode oxidizes ferrous fluoroborate to ferric fluoroborate.

摘要： A totally hydrometallurgical process for recovering in pure metal form all the lead contained in the active mass of used batteries, separated from the other processes, and desulphurized according to known processes, is disclosed.
The raw material is leached with an acid suitable for electrowinning. The residue from the acidic leaching is substantially formed by PbO₂ and organic substances.
This residue is transformed into lead sulphate by reacting it with concentrated sulphuric acid, and the so obtained lead sulphate is recycled to the desulphurization step.
By this system, a nearly complete solubilization of the lead contained in the active mass of the batteries is achieved, with the absence of any polluting residues. The electrolyte is the submitted to electrolysis in order to recover lead as cathodes.
