This paper reports the results of leaching experiments conducted with and without Thiobacillus ferrooxidans at the same conditions in solution. The extent of leaching of ZnS with bacteria is significantly higher than that without bacteria at high concentrations of ferrous ions. A porous layer of elemental sulfur is present on the surfaces of the chemically leached particles, while no sulfur is Download PDF . 86KB Sizes 413 Downloads 4402 Views. Report.

Director, Engineering Technical Support Center Hydrometallurgy is the most suitable extractive technique for the extraction and purification of manganese as compared to all other techniques including biometallurgy and pyrometallurgical processes. In the hydrometallurgical processing of manganese from its ore, the leach liquors often contain divalent ions such as iron, manganese, copper, nickel, cobalt and zinc along with other impurities
the use of electrochemical or chemical oxidation of iron(II) or copper(I) ions is dissolution are approximately constant for up to 80% dissolution for sized fractions of According to Burkin (2001), the leaching of chalcopyrite using copper(II)

Leaching of Cu 2 O with aqueous SO 2 solution is significant, since during the dissolution process, precipitation of copper as Chevreul’s salt also takes place under appropriate conditions. The dissolution is controlled by surface reactions and proceeds through both aqueous SO 2 and acid dissolution paths. An overall rate equation based on the above premise has been found to agree ORGANISATION FOR ECONOMIC CO-OPERATION AND DEVELOPMENT The OECD is a unique forum where the governments of 30 democracies work together to address the Stages of Hydrometallurgical Processes Supervisor Dr.Karimi Reyhane Mazahernasab 916181007 1 Sep2012 2.
