It is possible to use compacted anodes formed at low pressure for the direct electrowinning of lead from sulphide concentrates. An anode containing 5.5 per cent graphite, formed into a compact at 34 MN m-2, enables lead to be won at a current efficiency of about 80 per cent; the power consumption .at 150 A m-2 current density being 0.4 kWh per kg lead. It would be necessary to use diaphragm cells to obtain a sufficiently pure product. A conceptual design for a full-scale plant is presented, together with a cost estimate for the production of lead by a process based on direct electrolysis of compacted concentrates. It is unlikely that the proposed process will be economically competitive with the conventional lead smelting.
