AB  - The processing of zinc ore using hydrometallurgical methods leads to the formation and accumulation of a by-product called jarosite, which contains concentrated precious metals. In this study, we propose the recovery of In and its separation from Cu, Zn, Fe, Pb, and Ag. This study also presents a proposal for a new technological procedure for jarosite treatment. First we roasted the jarosite, and then the calcine collected was leached in water. The leaching extraction values obtained for Cu, Zn, Fe, and In were 91.07%, 91.97%, 9.60%, and 100.0%, respectively. Following the leaching of the roasted material in water, Pb, Ag, and most of the Fe obtained remained in the solid residue. The leaching solution was treated further by a precipitation process using NaOH, where In and Fe were precipitated and consequently separated from Cu and Zn. The In (OH)3 and Fe(OH)3 precipitates were dissolved further in a diluted H2SO4 solution, and then the cementation of In with Al was performed. We used HCl acid to remove Al from the In, after which unwrought In was obtained.

AB  - In this paper are presented the results of the first appearance of full pasivation during the treatment of the waste sulphuric-acid solution generated in the conventional copper electrorefining process. The copper anodes with non-standard content of nickel, lead, tin and antimony were used as material for electrochemical refinement. Nickel content in anodes was approximately 5 or 7.5 wt. %, and the summary content of lead, tin and antimony was up to 3 wt. %. Copper content was a difference of up to 100 wt. %. Chemical analysis of the waste solution from copper refining process which was used as electrolyte has shown that the Ni and As ions are present in concentrations of Ni - 20.5 g dm-3 and As – 4 g dm-3. The experiments were carried out in galvanostatic mode at current density of 250 A m-2, at electrolyte temperatures of T1 = 63 ± 2 0C and T2 = 73 ± 2 0C for a process duration of 72 h. The data obtained on the basis of the measured values of cell voltage for each anode where the nickel content was approximately 5 wt. % (anodes marked as A1-A4) and nickel content of approximately 7.5 wt.% (anodes marked as A5-A8) shown that using the anodes with lower nickel content (A2 and A3) leads to the appearance of full pasivation phenomenon at both electrolyte temperature. The apperance of full passivation for anodes with higher nickel content (A5-A7) is registered only at lower electrolyte temperature.

AB  - The aim of this study is synthesis of copper-sulfate pentahydrate from the waste sulfuric acid solution-mother liquor generated during the regeneration process of copper bleed solution. Copper is removed from the mother liquor solution in the process of the electrolytic treatment using the insoluble lead anodes alloyed with 6 mass pct of antimony on the industrial-scale equipment. As the result of the decopperization process, copper is removed in the form of the cathode sludge and is precipitated at the bottom of the electrolytic cell. By this procedure, the content of copper could be reduced to the 20 mass pct of the initial value. Chemical characterization of the sludge has shown that it contains about 90 mass pct of copper. During the decopperization process, the very strong poison, arsine, can be formed, and the process is in that case terminated. The copper leaching degree of 82 mass pct is obtained using H2SO4 aqueous solution with the oxygen addition during the cathode sludge chemical treatment at 80 A degrees C +/- A 5 A degrees C. Obtained copper salt satisfies the requirements of the Serbian Standard for Pesticide, SRPS H.P1. 058. Therefore, the treatment of waste sulfuric acid solutions is of great economic and environmental interest. DOI: 10.1007/s11663-012-9721-8
