With the exhausting of lead–zinc sulphide ores, the recovery of leadzinc oxide ores becomes more and more significant. Extensive work has been carried out at home and abroad on the treatment of lead and zinc oxide ores in reagent scheme, flotation flowsheets, and joint process. Sliming is one of the main reasons why the leadzinc oxides are difficult to recover.
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.. Galena is one of the most abundant and widely distributed sulfide crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite
In many locations where they had initially been recovering 90% of the assay values processing oxidized surface ore, with the rebellious sulfide ores they were recovering less than 50%. The rest of the precious metals in their ore simply flowed uselessly out from the mill and into the tailings pond.
It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper and leadbearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower ...
