Taschenbuch. Zustand: Neu. Neuware -This work deals with the solubilization of cobalt and copper by galvanic interaction chalcopyrite-heterogenite in sulfuric medium with the use of carbon as catalyst of the mechanism. pH(0.5;1.0;1.5 and 2) ,temperature (40;50;60;70 and 80°C), carbon mass(0. 4;1.5;2.6;3.7;and 4.8) and solid percentage(10;20;30;and 40%) were the parameters studied to swallow the influence of these on the copper solubilization of chalcopyrite and cobalt III oxide.X-ray diffraction (XRD), atomic absorption spectrometry (AAS), X-ray fluorescence (XRF) and inductively coupled plasma atomic emission spectrometry (ICP) were the methods used for the mineralogical and chemical characterization of the samples, solutions and leaching residues. They revealed a content of 31, 28% copper and 0.59% cobalt respectively for the chalcopyrite and heterogenite samples. A first series of pre-leaching tests of the heterogenite and chalcopyrite were carried out in order to reduce the interference of the different soluble minerals present in the studied samples.Books on Demand GmbH, Überseering 33, 22297 Hamburg 80 pp. Englisch.
