These deposits formed the basis of Australias lead-zinc silver mining industry. Resources. Lead was the first metal mined in Australia at Glen Osmond in South Australia in 1841, after the wheel of a cart being pulled up a rough track accidentally exposed some lead-zinc ore.

sedimenthosted leadzinc deposits in earth history

2 Lead-zinc oxide ore In the lead-zinc oxide ore, lead is mainly present in the state of leucite and lead bismuth, and zinc is mostly present in the state of smithsonite and willemite. Oxidized ore is gradually formed by the action of long-term weathering and groundwater containing carbonate. Sediment-hosted Pb-Zn deposits contain the worlds greatest lead and zinc resources and dominate worldproduction of these metals. They are a diverse group of ore deposits hosted by a wide variety of carbonate andsiliciclastic rocks that have no obvious genetic association with igneous activity. A range of ore-forming processes in a variety of geologic and tectonic environments created these ...

The first subtype is clastic-dominated lead-zinc (CD Pb-Zn) ores, which are hosted in shale, sandstone, siltstone, or mixed clastic rocks, or occur as carbonate replacement, within a CD sedimentary rock sequence. This subtype includes deposits that have been traditionally referred to as sedimentary exhalative (SEDEX) deposits. The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.

2013-12-5 3.1 Distribution and characteristics of lead/zinc minerals in China Associated lead and zinc ores typically contain a much higher grade of zinc than lead. Chinese mines include few single lead or zinc deposits. The average grade level of the above-medium-sized lead/zinc mines in China is 6.48%, including 1.99% lead and 4.49% zinc 22. Mar 30, 2020 The zinc deposits (resources) that are known today to be presumably mineable will ensure a much longer period of secure zinc supply. An end to zinc ore mining is not foreseeable.
