Size Of Cu Zn Pb Of The Gold Ore

The Pb isotopic compositions of sulfides (207 Pb/ 204 Pb = 15.420–15.525, 206 Pb/ 204 Pb = 18.423–18.536, 208 Pb/ 204 Pb = 37.135–38.208) indicate that the Pb in the Atash-Anbar gold deposit is a mixture of crust and mantle components. We conclude that (1) the Atash-Anbar is an IS epithermal system that (2) resulted from Eocene subduction ...

The Nannihu ore field is largely represented by the Nannihu Mo-W deposit, Luotuoshan Zn-Cu-W deposit, and Lengshuibeigou Pb-Zn-Ag deposit. Mo-W mineralization at Nannihu occurs in the contact zone between the Nannihu intrusion and the wall rocks, showing typical characteristics of the porphyry-type deposit.

Jinchanghe is a Zn-Pb-Fe-Cu skarn deposit in the northern Baoshan block, southwestern China.

The data for pyrite in bedded ore, massive ore, and disseminated ore are from Peng et al., (2022); the mantle range of δ 34 S and Δ 33 S values is from Bekker et al. (2016); note that the insets show the frequency distribution of Δ 33 S values for pyrite and for all sulfide minerals from the Hongtoushan Cu-Zn-Au deposit.

The giant Dongshengmiao is the third largest Pb–Zn deposit in China (Wang et al. 2014), with total metal reserves of 4.83 Mt Zn (@ 2.85%), 0.96 Mt Pb (@ 0.67%) and 0.11 Mt Cu (@0.86%; Long 2009).The enrichment of massive pyrite accompanying Zn–Pb–Cu mineralization also makes it possible to make sulfur acid through mining pyrite.

The Huogeqi is a large Cu-Pb-Zn polymetallic deposit having a metal reserve of 0.7113 Mt Cu at an average grade of 1.35 % Cu, 0.78 Mt Zn at 1.46 % Zn, and 0.97 Mt Pb at …
