AP3894 to the zinc circuit and SIPX and AF242 to the Lead circuit) decreased with time. PAX (Strong collector) was being dosed to the zinc circuit whilst SIPX (Medium strength collector) was being dosed to the lead circuit. As a consequence, recovery of lead was higher in the zinc circuit than in the lead circuit.

Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a tool to understand the …

A plant survey was carried out on the lead secondary rougher and scavenger banks of the Lead/Zinc Concentrator of Mount Isa Mines Limited. Sizing analysis of the survey samples demonstrated that a major limiting factor to overall lead recovery in this section of the plant was the diminished recovery of the fine galena in the minus 5 microns particle size fraction.
