Flowsheet development for selective Cu-Pb-Zn recovery at
The high-Cu ore could not be processed via the current RPZC flowsheet to produce distinct Cu, Pb and Zn concentrates. A feasible flowsheet was developed based on a modified Black Mountain (Cu-Pb-Zn concentrator) processing route for the Cu circuit.

Preferential Flotation of a Refractory Cu-Pb-Zn Polymetallic Ore
According to the mineralogy of the polymetallic ore the process of preferential flotation of copper was adopted, and the separation of lead, zinc and sulfur were carried out and implemented Four products, including copper concentrate assaying 22.67% Cu at a recovery of 91.77%, lead concentrate assaying 18.10% Pb at a recovery of 12.74%, zinc concentrate...
Zinc smelting - Wikipedia
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a ...
Sulfidation roasting of low grade lead–zinc oxide ore with
Jun 01, 2010 · Onal et al. (2005) investigated the flotation and gravity separation of Aladag oxide lead–zinc ores which contained 10.2% Pb and 11% Zn. The results show that a lead concentrate with 65.4% Pb was produced with about 80% recovery while almost all zinc remained in the tailings and could not be recovered by addition of different reagents due to ...
Zinc and Lead - Glencore
Zinc Zinc is mainly used to galvanise steel or iron – that is, to apply a zinc coating to stop it rusting. Galvanised steel is used in buildings, cars, white goods and electronics. The strength and flexibility of zinc alloys mean they are ...
As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu-Pb bulk concentrate is recovered with xanthate

Chapter 27 Lead–zinc–silver deposits of Myanmar | Geological
Currently, the oxide ore (‘halo ore’) from the open pit only is processed at Bawdwin, to yield a concentrate averaging 41.73% Pb, 9.03% Zn and 3.06% Cu. The lower ore grades present a problem for the old Namtu smelter, which was designed for processing sulphide ore and requires lead concentrates to have a minimum content of 57% Pb with 10 ...
Features and Flotation of Complex Cu-Pb-Zn Sulphides
Abstract. Problems arising during flotation of complex Cu-Pb-Zn sulphide ores are in general of geological origin. The features of these ores are reviewed, stressing that mineralogical studies extending to process mineralogy are prerequisite for a consistent flotation process.

Polymetallic Flotation Equipment - Complete Ore Process Plant
This ore processing plant is for the flotation of 2 base metals (Cu/Pb/Zn/Co/Ni/etc.) which may or may not contain precious metals. These ore deposits are called polymetallic by geologists and metallurgists. This system allows you to recovery by way of differential or sequential flotatio, the sulphide metals in 2 separate concentrates. Examples include: Copper, Lead, Zinc, Cobalt, Nickel ...
