cost of zinc concentrate processing

  • Zinc processing Britannica

    Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products.. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient.

  • Mineral Concentrate Marketing Treatment Charges & Penalties

    Base charges for zinc concentrates are very high, com­paratively speaking, on account of the cost of the process, particularly the item of fuel, which is usually gas. In fact, zinc smelters are ordinarily built near the gas supply, be­cause it is cheaper to transport the ore than the fuel.

    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 measures are taken to prevent it. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphale
