Lead and zinc minerals play an important leading role in China's non-ferrous metal industry, but their flotation separation process is often affected by the presence of ions in the pulp. There may be some unavoidable ions introduced by mineral self-dissolution and fluid inclusion release in flotation pulp of sulfide ore[1]. These ions will inevitably have a significant effect on the separation of lead-zinc sulfide minerals. Pb2+ is an unavoidable ion introduced into the flotation pulp due to the self-dissolution of galena, which has a certain influence on the separation of lead-zinc sulfide ore. Therefore, the focus of this study is the separation and mechanism analysis of Pb2+ on lead-zinc sulfide ore.

Most fluid inclusion data were gathered on siderite, quartz and calcite of various stages of vein-type mineralization. Almost all samples contained inclusions with variable liquid to vapor ratio (LVR), which made the measurements more difficult.
Controls on cobalt and nickel distribution in hydrothermal sulphide deposits in Bergslagen, Sweden - constraints from solubility modelling
Published in GFF, 2020
Due to the metamorphic overprint, fluid inclusion studies are not an option for sampling the original mineralizing fluids. Jansson et al. (2017) instead used the approach of Cooke et al. (2000) for adding constraints on probable fluid compositions and depositional mechanisms. Based on an integration of basin analysis, ore and gangue mineralogy, and solubility modeling, Cooke et al. (2000) derived a twofold division for sediment-hosted Zn deposits worldwide: (1) Selwyn-type deposits, formed from hot (250 °C), acidic and reduced hydrothermal fluids carrying metals and H2S together; and (2) MacArthur-type deposits, formed from cooler (150 °C), near neutral and oxidized (SO42- stable), saline brines carrying metals only.
