30 September 2017 Abstract: In order to extract gallium from a high-silica-content flue dust generated in corundum production, a mixed acid solution of H2SO4 and HF was used for leaching... of micro areas in this corundum flue dust indicate that the content of gallium in silica-enriched phases was high; this portion of gallium was insoluble in H2SO4 solution. The leaching rate of gallium......

Processing and Bioengineering,Central South University, Changsha 410083 , China) Abstract: Thermodynamics and technologies of separating gallium and germanium from ferrous powder produced from zinc leach residues were investigated by corrosion process. Thermodynamic results show that under the specific conditions on pH value and potential φ, metallic iron may precipitate as goethite, while gallium......
of small amount gallium (up to 0.06%) on the corrosion behavior of pure aluminum (99.99%,4N) in chloride solution was investigated using a potentiodynamic polarization technique.It has been found that the open circuit corrosion potential and the pitting potential shifted in the active (negative) direction with increasing gallium content,while corrosion rate and pitting occurrence factor......

in the leaching solution. More than 60% of Pb was recovered in the form of PbCl2, as shown in Fig. 13. The PbCl2 product containing 74.3 wt.% Pb exhibited a high purity without any additional characteristic... HCl solution with a liquid-to-solid ratio of 20 mL/g at 90 °C for 2 h. A PbCl2 byproduct with a high purity was obtained by cooling crystallization. (3) During alkaline leaching, the remaining 90......
