Recent Advances in Hydro- and Biohydrometallurgy

<p>This Special Issue of Minerals presents recent select studies that highlight advances in the fields of hydro- and biohydrometallurgy. It aims to attract the interest of readers and especially of young scientists and students in this fascinating scientific discipline. <br />The topics addressed include the following:<br />• Stirred reactor and heap leaching of laterites (limonitic and saprolitic) as well as iron control during atmospheric acid leaching;<br />• Leaching of a typical porphyry copper sulfide deposit from Antofagasta Chile using chloride-ferrous solutions;<br />• Leaching of chalcopyrite ores with various leaching media;<br />• Leaching of white metal from a Teniente converter in NaCl-H2SO4 media; <br />• Study of the galvanic effect of pyrite and arsenopyrite during the leaching of gold ores;<br />• Leaching of marine nodules in the presence of reducing agents to extract Mn;<br />• Bioleaching of gold ores in the presence of iodide-oxidizing bacteria;<br />• A two-step sequential leaching process involving bioleaching and chemical leaching to treat apatite ores containing P and U impurities;<br />• Bioreductive dissolution of iron minerals present in monazite in stirred reactors using Acidithiobacillus (A.) species;<br />• Heap leaching of municipal solid waste incineration bottom ash (MSWI BA) for the recovery of Zn and Cu.</p>
