One prevalent form of copper concentrate contains gold and silver, like the one produced by Bougainville Copper Limited from the Panguna mine from the early 1970s to the late 1980s. [35] The typical contract for a miner is denominated against the London Metal Exchange price, minus the TCRCs and any applicable penalties or credits.
Wet chemical process for extracting gold and silver by direct oxidizing, sulphuric acid disintegration of carboncontaining arsenopyrite (FeAsS2) concentrates containing silicate gangue or silicate and pyritic gangue, in which arsenic and iron are fully transformed into solution and the precious metals are quantitatively enriched in the silicate residue.

Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 6070% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic ores.

Assaying, in chemical analysis, process of determining proportions of metal, particularly precious metal, in ores and metallurgical products. The most important technique, still used today, grew largely out of the experiments of the ancient alchemists and goldsmiths in seeking to find or create precious metals by subjecting base metals and minerals to heat.
Albion process. The Albion process is an atmospheric leaching process for processing zinc concentrate, refractory copper and refractory gold The process is important because it is the most costeffective method currently in use for extracting both the zinc and lead from concentrates that contain high lead levels (7% or greater) Zinc and lead often occur together and large remaining zinc ...

Mar 01, 2015· The pyritic copper–gold ore used in this study was obtained from a copper–gold mine in Asia. The pyrite rougher concentrate was obtained by twostage copper and pyrite rougher flotation using the conditions in Table 1 and reported in Agorhom et al. (2013).However, in the present studies, the focus is to examine flotation depression of pyrite after regrinding the combined pyrite rougher ...

The majority of gold ores are classified refractory because the gold mineralogy is contained in sulphides. This type of gold is typically very fine gold or locked in solid solution within sulphide minerals pyrite and arsenopyrite (FeAsS). The arsenic bearing pyrite is commonly known as arsenian pyrite and can contain gold in its structure.
METHOD FOR PROCESSING PYRITIC CONCENTRATE CONTAINING GOLD, COPPER AND ARSENIC The invention relates to a method for processing pyritic copper sulphide concentrate, in which, in addition to copper, there is arsenic and gold bound to the sulphide minerals, or invisible gold. In the method concentrate is leached into... WO/2009/069781A1
Apr 17, 2016· The great Huelva pyritic copper deposits of Spain carry a little gold and silver. At Cerro Colorado, these metals were concentrated above the chalcocite zone into the solabeled "gossan". This material with a content of 0. 080. 09 oz Au and oz Ag per ton is amenable to cyanidation.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
