Bagdadts sulphide-copper flotation mill has recently been revitalized in much the same way as the mine. The main feature of the mill improvement was a sys­ tem of alkalinity (pH) control which boosted recovery of sulphide-copper by 10 percent. This close pH control also involved additional controls of density and initial ore feed.

copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or open-pit mining, is the predominant mining method for copper in the world. After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical.

Copper isotope variation in chalcopyrite can be observed throughout the Bingham Canyon Mine and used to understand high temperature mineral processes. At Bingham, copper isotope variation in hypogene minerals (e.g. chalcopyrite) ranges from -0.05 to +1.95‰. Two sections spanning the deposit were chosen to observe spatial variation in
