    The value of the free copper, gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate, LME copper price and LMBA gold and silver price. In this example the recovery rate for a copper smelter is 98.0%. The value of free gold and silver is normally greater than the value of the free metal for copper.

  • Zinc processing

    Zinc processing - Zinc processing - Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world''s output originates in North America and Australia.

  • Tank leaching

    Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

  • Zinc | Geoscience Australia

    Zinc (Zn) was used in Rome and China more than 2000 years ago as a component of brass which is a zinc-copper alloy. The Romans and Chinese smelted zinc ores such as calamine (zinc carbonate) with copper to produce brass, used for coins, containers, armour and jewellery. They did not actually realise that zinc was a metal.
