Lead and Zinc

6.1.2 Lead and Zinc Ore beneficiation Due to low zinc content, run-of-mine zinc-bearing ores must be concentrated before smelting and refining. Beneficiation, which usually occurs at the mine, consists of crushing, grinding, and flotation to produce concentrates of 50 to 60 percent zinc. Lead ore also requires processing to

Process mineralogy of the Ishiagu lead-zinc deposit, Nigeria

A study was performed to characterize the Ishiagu lead-zinc deposit prior to beneficiation. The study included the use of XRD, SEM and both reflected- and transmitted-light microscopy. The results showed that the ore consists mainly of galena (PbS), sphalerite (ZnS) and quartz (chert), with pyrite, siderite and chalcopyrite occurring as trace minerals. The textural relationships …

First experimental work was grinding tests to reduce -106 μm size fractions with two …

BENEFICATION OF LEAD & ZINC ORES

Usually lead sulphides are selectively floated from the ore followed by activation and separation of zinc in case of complex lead-zinc ores. Bulk flotation followed by separation of lead and zinc differential flotation is not quite uncommon. Table 3.5 at the end of this chapter, summarizes the benefication results of lead & zinc Ores studies.
