In this research, the selective flotation of galena and sphalerite minerals was evaluated from a pyrite-rich lead-zinc sample. An optimum mixture of selective collectors against pyrite and also organic/inorganic pyrite depressants was obtained in the flotation of galena and sphalerite by an experimental mixture design. The effect of different collectors and pH values were investigated in the ob...

The Nanmushu Zn–Pb deposit is a large-scale and representative in the Mayuan ore field on northern margin of Yangtze Block. This study investigates trace element geochemistry sphalerite from this using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). results show that main elements include various elements, such as Mn, Fe, Cu, Ga, Ge, Ag, Cd, Pb, Co, Hg, Tl, In, Sn, Sb. ...

The Sichuan–Yunnan–Guizhou (SYG) Zn–Pb metallogenic zone in SW China contains >400 carbonate-hosted hydrothermal deposits. Some of these, such as the Huize, Tianbaoshan, and Daliangzi deposits, are super-large deposits with significant reserves Cd, Ge, Ag. However, sources these metals remain controversial. This study investigated Cd isotopic geochemistry Huize deposit, largest deposit SYG area...

Cinnabar (α-HgS) is the most common sulfide of mercury while metacinnabar (β-HgS), a high-temperature homogeneous polymorph sulfide, relatively rare, and α phase cinnabar transforms to β at 344 °C. Meanwhile, there complete isomorphic series between HgS HgSe, occurrence Se-bearing great significance for exploration selenium resources. We studied through microscopic observation, electron-probe m...

Abstract The McArthur River (HYC) Zn-Pb-Ag deposit in the Carpentaria Zn belt, northern Australia, is one of world’s largest and most studied sediment-hosted base metal deposits, owing to its lack deformation preservation sedimentary ore textures. However, formation process (syngenetic vs. epigenetic) still a subject controversy. In this paper we focus on key characteristics HYC that remain une...
