05.05.2017A conservative estimate of the requirements of a properly constructed, continuously operating furnace of 5 to 10 tons daily capacity would seem to be 3.000 to 3.500 kw-hr. per ton of zinc metal produced, smelting a cold charge, or 2,500 to 3,000 kw.-hr. with a preheated charge. This consumption should be lowered by larger and standard operations.
