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
Mineral processing is not completely known and further research into their mechanisms is being performed. Depressants and activators are used to selectively separate one mineral from another. Depressants inhibit the flotation of one mineral or minerals while activators enable the flotation of others. Examples of these include CN, used to depress all sulfides but galena and this depressant is believed to operate by changing the solubility of chemisorbed and physisorbed collectors on sulfides. This theory originates from Russia. An example of an activator is Cu ions, used for the flotation of sphalerite. There are a number of cells able to be used
