Pb/Zn Ores

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, dithiophosphate and flotation reagent blends.

Middle Triassic Cu–Pb–Zn Skarn mineralization in the Wulonggou gold ore

Cu–Pb–Zn skarn related granodiorite and diorite formed at 245–243 Ma. Phlogopite Ar–Ar dating constrains that skarn mineralization occurs at 240 ± 1 Ma. Middle Triassic ore-related granodiorite and diorite formed by magma mixing. Mantle-derived magma plays a vital role in the formation of skarn mineralization.

The Rammelsberg deposit

The Rammelsberg is a type locality for shale-hosted, sedimentary-exhalative (SEDEX) Zn-Pb-Ag deposits but is unusual because of the high grade (27 Mt at 19% Zn, 9% Pb, 160 g/t Ag) and high copper-gold content (1% Cu, 0.5-1 g/t Au) of the sulfide ore.

Ore deposit types and their primary expressions

Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. Like all crustal rocks, they consist of minerals formed by geological processes. There are four basic geological requirements for any ore deposit to form (Figure 1): - a process or geological setting that allows the ore deposit to be preserved. Figure 1.
