Abstract
The process for recovery of lead, copper, zinc, precious metals and other elements consists of (a) calcining the concentrate under oxidising conditions; (b) lixiviating part of the prod. under approx. neutral conditions; (c) introducing the remaining part into the iron pptn. stage to neutralise the free acid; (d) subjecting the residues from (b) and (c) to acid lixiviation to solubilise the copper and zinc ferrites; (e) removing copper from the soln. from (b) by solvent extraction and electrolysis, followed by (f) removing zinc by electrolysis; (g) recovery of lead and precious metals from the residue from (d) in which they are present in sulphated form by solubilising in chloride medium.
