The bornite was collected from the Yushui copper mine in Meizhou, Guangdong, China. After grinding and sieving, the 200 mesh ( mm) mineral was obtained for experiments. Chemical analysis conducted by Xray fluorescence (parameters given in Section ) showed that the bornite sample contained ( w/w ) % Cu, % Fe, and % S ( Table 1 ).

Abstract. As applied to copper sulfide ores, Mössbauer spectroscopy method is suitable for the analysis noted. Bornite (formally Cu 5 FeS 4) is a significant part of copper ore and identification of its properties is important for economic exploitation of commercial copper ore deposits. A series of natural bornite samples was studied by 57 Fe...

Companies can offset volatility and help maintain their value by efficient extraction and mine operation. The discovery of a new deposit in the vicinity of the operating mine may also increase mine life and stock value. If no new deposits are found then production winds down as reserves decrease, moving the mine toward the closure stage. Closure
