Abstract
A process for selectively leaching lead and silver chlorides from a sulfide ore residue in a rapid time which comprises brine leaching the residue under pressure at a temperature above the normal boiling point of the solution, preferably above 100.degree. C. Modifications are leaching at the agglomeration temperature of sulfur when present in the residue to agglomerate the sulfur for ease of recovery, and flashing from leach temperature to ambient as a lead chloride crystallization recovery step to produce a large crop of lead chloride crystals per pass.
