Zinc smelting Wikipedia
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific

Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible. Zinc smelting; Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth
How to Process Oxidized Lead-Zinc Ore by Flotation
The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue. The association of the
Cost of Producing Concentrates from Ore
From the viewpoint of mineral economics, the ultimate and significant production cost is that per unit of metal produced rather than the cost per ton of ore treated. This viewpoint is natural to processors of ores whose final product is refined or unrefined metal, whether they be companies engaged solely in smelting, or integrated companies engaged in mining, milling, and smelting operations.
