Leaching and Kinetic Modelling of Molybdenite Concentrate Using Hydrogen Peroxide in Sulfuric Acid Solution
Leaching of molybdenite concentrate with hydrogen peroxide in sulfuric acid solution was investigated to determine the effects of reaction time, reaction temperature, H2O2 concentration, H2SO4 concentration, pulp density and rotation speed on molybdenum extraction and molybdenite dissolution kinetics, using the Taguchi method. From analysis of var...

متن کاملThe Influence of Mechanical Activation of Chalcopyrite on the Selective Leaching of Copper by Sulphuric Acid
Base metal sulphides are an important source of various metals. They are typically intergrowth and due to the complex nature of their ores, the hydrometallurgical technique is the very convenient way of extracting the desired component. If it is possible to extract the metal from an ore selectively, the subsequent processing steps become less complicated. Mechanical activation seems to be a fav...
متن کاملKinetics and Mechanism of Sphalerite Leaching by Sodium Nitrate in Sulphuric Acid Solution
Interest for application of hydrometallurgical processes in a processing of complex sulphide ores and concentrates has increased in recent years. Their application provides better metal recoveries and reduced emission of gaseous and toxic ageneses in the environment. The kinetics and mechanism of sphalerite leaching from complex sulphide concentrate with sulphuric acid and sodium nitrate soluti...
متن کاملComparison of various extractants for recovery of Copper from Sarcheshmeh Chalcopyrite concentrate Ammonia/Ammonium Carbonate Leaching
Solvent extraction of copper from the copper leach solution obtained from the ammoniacal carbonate leaching of the Sarcheshmeh copper concentrate was carried out, and the performance of CP-150, LIX984N, and Kelex100 as well as the effects of different parameters involved were investigated. According to the results obtained, the extraction kinetics of all the three extractants was fast. High con...
