Zinc Extraction From Zinc Oxidized Ore Using (nh4)2so4

Zinc Extraction From Zinc Oxidized Ore Using (nh4)2so4

Nov 09, 2020 An improved method of (NH4)2SO4 roasting followed by water leaching to utilize zinc oxidized ores was studied. The operating parameters were obtained by investigating the effects of the molar ratio of (NH4)2SO4 to zinc, roasting temperature, and holding time on zinc extraction. The roasting process followed the chemical reaction control mechanism with the apparent activation.

History Deposits And Production Of Zinc

Mar 30, 2020 Zinc ore is no longer mined in Germany today, and the zinc concentrations in the deposits are too low for cost-effective zinc extraction. The raw material for zinc extraction has therefore traveled a long way, for example, from Australia - mostly by ship - before it is processed into zinc.
