  • Gold-Copper Ores ScienceDirect

    1/1/2016· Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a co-product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron-sulfide minerals. Due to this variable gold

    1/1/2005· As expected, the copper in the circuit reduced to a low level, but when sulfide copper–gold ore processing resumed, the copper concentration in the leach circuit did not attain previous levels even though a higher copper orebody was being mined. The copper recovery plant was operated intermittently for a few months and was eventually shut down. The combined effects of the lead and

    In the case of Northparkes we are processing this ore into copper, gold and silver. Two stockpiles receive the ore, which is then processed through several stages including grinding, flotation, concentrate thickening and finally filtration. In early 2015 we became the first mine in Australia to use a Scanning Electron Microscope (SEM) in our onsite laboratory. The SEM provides us with a wealth

    The copper-gold ore deposit at Gedabek in western Azerbaijan is described, together with the various processes that are used to extract the gold, silver and copper from these ores. The processes include heap leaching, agitation leaching and flotation. Geometallurgy is used to classify the various types of ore found in this complex ore body and to determine the optimum processing route for each

It is most commonly reported as the specific energy per tonne of material processed (kWh/t). However it may be more useful to present the metal specific energy (MSE) in terms of final metal product as this

  • MINING AND OFF-SITE PROCESSING STUDY FOR BARBARA

    The Mining and Offsite Processing Study is based on the production of copper, gold and silver metal, with ore to be mined from two open pits at the Barbara Project (the North pit and the South pit). The Study assumes that the mined ore would be trucked to offsite facilities for processing, with sulphide ore to be processed at Glencore’s Mt Isa operations and oxide ore to be processed at

  • The leaching and adsorption behaviour of gold ores

    There are many non-idealities in gold processing which are becoming increasingly important as simple free-milling oxide ores are depleted. During cyanidation and adsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it

    The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60%

  • Copper extraction Wikipedia

    The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores

    Home to a major oxide copper gold deposit producing copper, uranium, gold and silver, the site hosts an underground mine and an integrated metallurgical processing plant. The project was opened in 1988 by WMC Resources, after discovering the large deposit in 1975. It was later expanded under an A$1.9 million programme, raising its capacity to 200,000tpa of copper and 4,300tpa of uranium, plus
