• Lead extraction in MSA leach average approximately 90% across all lead mineralogy based on a single pass through the leach circuit. The lead extraction from
the MSA leach residue average 98% resulting in an overall recovery through the
flotation and hydrometallurgy processes of 81.3%.
• Lead cathode was produced at current densities between 300 and 350 A/m
2 , which
equates to a cathode plating rate of 70,000–80,000 tpa. Cathode quality exceeds
99.995% lead.
