| Abstract: |
| A high silicon zinc oxide ore was treated to investigate the effect of sulfuric acid concentration and neutralizing condition on extraction percentage of Zn and SiO 2. The experiments focused on how to make slurry easier for filtration and improve technique of zinc extraction. The mechanism and technology of concentrated and dilute sulfuric acid leaching was demonstrated respectively. The necessity and feasibility of introducing microwave into hydrometallurgy was also discussed in this paper. |
