Pressure leaching of zinc silicate ore in sulfuric acid medium LI Cun-xiong(李存兄), XU Hong-sheng(徐红胜), DENG Zhi-gan(邓志敢), LI Xing-bin(李兴彬), LI Ming-tin(李旻廷), WEI Chang(魏 昶) Faculty... and the results showed that zinc exists mainly as hemimorphite and smithsonite in the sample. Sulfuric acid pressure leaching of zinc silicate ore was carried out to assess the effect of particle size, sulfuric......
Formation Process of Porous Anodic Film in Sulfuric/Oxalic Acid Mixture Electrolyte杨培霞,安茂忠,郭洪飞摘 要:Porous anodic alumina film (PAA film) was fabricated on pure aluminum in sulfuric/oxalic acid mixture electrolyte and was compared with the film prepared in single sulfuric acid electrolyte. Scanning electron microscopy (SEM) was employed to investigate......
