ores processed to be zinc

LeadZinc ores Danafloat

Flotation separation and recovery of lead and zinc concentrates from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved quite effectively. Silver often provides highly significant economic value, if not the greatest value, with the silver most often associated with the galena mineralization which is fortuitous since smelters pay more for silver in lead vs. zinc concentrates.


More selective collectors are used and the pulp chemistry adjusted to achieve optimum separations and recoveries. Thus, for example, the three metals in copper/lead/zinc ores can be floated into three concentrates, each containing one of the metals. The process of flotation is sometimes also used in electrochemical waste treatment .

India Was the First to Smelt Zinc by Distillation Process

Smelting process of zinc. This roasted ore was again mixed with more charcoal powder, salt and borax as flux and thoroughly mixed with cow dung and water, then made in to balls of 5 to 10mm diameter by hand rolling. These pellets were dried in sun and then filled into the brinjal shaped retorts.

Oxide ores cannot be reduced by carbon. Why? Quora

Dec 22, 2017· Iron Oxide is reduced by carbon (coke) to form iron metal. This is a wellknown process for reduction of iron oxide. Other oxides of metals, such as Zinc and Nickel can be similarly reduced using carbon. More recently, a process for Direct Reduction of Iron (DRI), using synthesis gas (1:1 mixture of H2:CO) is also prevalent.
