Zinc consumption in the new system has been reduced by about a quarter. 66kg of zinc are used per tonne of material. It was possible to reduce specific energy consumption to around 60%. In addition, production stops and the transportation of hazardous substances (CO2 emissions) have been eliminated and the chemicals H2O2 and NH3 are no longer used.• reagent consumption and cost varies from one country and loion to the next.

Using zinc oxide as sintering aid, uniaxially pressed discs and cold isostatically pressed YDT thimbles from these powders were sintered at temperatures as low as possible (1650oC).

The total acid consumption per ton of ore processed was higher in the case of aeration, which was supported by the higher pH of the PLS. But the net acid consumption per ton of copper produced was the same in the two cases. Approximately 5% of the total iron added toAn experimental program was conducted on a zincsulphide ore containing 15% zinc in support of the development of the Teck Cominco HydroZinc™ process. The two primary types of experiments that were conducted were bacterially assisted short column experiments, and controlled potential, isothermal, chemical leaching experiments.
