copper mining and gold ore processing operations

  • Copper extraction

    The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors. As in all mining operations the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of

  • Ore processing operations at Newmont Boddington Gold

    The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.

    Of all the methods of extracting gold processing it from its ore I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery

  • Copper Ore Processing Methods

    The four major steps in the production of marketable copper are mining concentrating smelting and refining. In a few instances however leaching takes the place of concentrating smelting and refining. At present although considerable leaching and directsmelting ores are produced the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
