the magnetic induction significantly improves the concentrate yield. This means that magnetic induction has a great influence on particle inclusion. Non magnetic phases such as zinc oxide, zinc sulfide... and zinc oxide. The increase of magnetic induction improves the distribution rate of zinc ferrite in concentrate and about 45% of calcium attached to zinc ferrite is distributed to magnetic......

, Centr)Abstract:The standard lead and zinc concentrate were prepared from cyanide tailings derivatives. By using X system in the atmospheric pressure for oxidize leaching, the influences of leaching potential, antioxidants, total acid amount, reagent A, reagent B, leaching time and leaching temperature on zinc recovery rate, zinc concentrate grade and lead leaching rate were studied. The results......

density electrolysis. 2 Experimental 2.1 Solution preparation All chemical reagents, i.e. zinc sulfate, cadmium oxide, copper sulfate, ammonium sulfate, sulphuric acid and ammonia were used... or ammonia-ammonium sulphate solution while the other two had zinc, cadmium and copper ions in the different solutions, respectively. Cadmium oxide was dissolved in water by adding concentrated sulphuric......
Preparation and characterization of ultrafine zinc oxide powder by hydrothermal method SHEN Xiao-yi(申晓毅)1, ZHAI Yu-chun(翟玉春)1, ZHANG Yan-hui(张艳辉)2 1. School of Materials... as dispersant agent, ultrafine zinc oxide powder was synthesized by hydrothermal method. Influence of NaOH concentration on morphology of ZnO powder was studied. The as-synthesized ZnO powder looked like......
