21-05-2017 The attraction of semi-autogenous grinding in copper operations is that they can accommodate ores that are hard or soft, wet or dry, sticky or otherwise. The SAG mill can handle everything that is presented to it, regardless of coarseness or fineness, or hardness or moisture content, and from it prepare satisfactory feed for subsequent secondary grinding

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Porphyry copper ore is challenging X-ray mineralogy. The mineralogy of the ore, concentrates and residues is complex. Twenty or more minerals are to be quantified in most of the samples. Peak overlap is massive and may mask minor phases. Clays and other layered material make a reproducible sample preparation difficult.

12-01-2018 For example, an ore containing the mineral chalcopyrite (CuFeS2) derives its value from the contained copper. Chalcopyrite does not in and of itself have any direct use as a mineral. Once chalcopyrite is concentrated (separated from the gangue), it requires further trewatment to extract copper via chemical (hydrometallurgical or pyrometallurcial) methods.

Copper extraction refers to the methods used to obtain copper from its ores.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).
