Refining Primary Lead by Granulation–Leaching–Electrowinning

Because the granulation-leaching-electrowinning process does not require drossing, emissions associated with bullion transfer and the increasing cost of managing such emissions can be eliminated. As the bullion is immediately leached, silver and gold contained in the leach residue are available for processing much sooner than presently practiced.

3). Thus, the gold particles are in electrical contact with that electrode. Since secondary electrowinning may also be carried out simultaneously in that cell, the gold from both sources is effectively combined at the cathode. However, initially the EWEF cell was used on its own to electrowin gold from original and diluted eluate solutions.
