Lead(II) sulfate primary lead sulfide ore, galena. A number of lead basic sulfates are known: PbSO·PbO; PbSO·2PbO; PbSO·3PbO; PbSO·4PbO. They are used in manufacturing of active paste for lead acid batteries. A related mineral is leadhillite, 2PbCO·PbSO·Pb(OH). At high concentration of sulfuric acid (>80%), lead hydrogensulfate, Pb(HSO), forms. Lead(II) sulfate can be dissolved in concentrated HNO, HCl, HSO producing acidic salts or complex compounds, and in concentrated alkali giving soluble hexahydroxidoplumbate(II) [Pb(OH)] complexes. Lead(II) sulfate decomposes when heated above 1000 °C: Lead(II) sulfate Lead(II) sulfate (PbSO) is a white solid, which appears white in microcrystalline form. It is also known as "fast
Iron oxide copper gold ore deposits named as IOCG, by discovery and study of the supergiant Olympic Dam copper-gold-uranium deposit, and South American examples. IOCG deposits are classified as separate to other large intrusive related copper deposits such as porphyry copper deposits and other porphyry metal deposits primarily by their substantial accumulations of iron oxide minerals, association with felsic-intermediate type intrusives (Na-Ca rich granitoids), and lack of the complex zonation in alteration mineral assemblies commonly associated with porphyry deposits. The relatively simple copper-gold +/- uranium ore assemblage is also distinct from the wide spectrum of Cu-Au-Ag-Mo-W-Bi porphyry deposits, and there is often no metal zonation within
