mine, will develop the deeper I Series reefs and associated goldcopper mineralisation. There are similarities in the size, mine types and the process routes between the Cadia Valley Mines, first commissioned in 1998 and the Telfer Project. Both projects comprise large open pit and smaller underground mines with copper and gold mineralisation.
ized in all phases of copper production. Both machine and human productivity have increased dramatically. This chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or solvent extraction and electrowinning. The chapter begins with an overview of the history of cop
Doe Runs Sweetwater Mine and Mine No. 29 are located nearby. So much is happening underground at any moment, we often call our mines underground cities. Our metal mining operations in the Viburnum Trend contain some of the worlds purest lead. We produce lead, copper and zinc concentrates to sell around the globe.

#0183;#32;This paper introduces Zijinshan Mine where an integrated process was developed and applied to recover copper from lowgrade copper sulfide ore and acid mine drainage (AMD). The process includes the main operations of millingflotation, heap bioleaching, solvent extractionelectrowinning (HBLSXEW) and copper precipitation.
Copper extraction refers to the methods used to obtain copper from its 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).
#0183;#32;The Olympic Dam mine produced 194,100t of copper, 4,045t of uranium oxide, 111,368oz of refined gold and 982,000oz of refined silver in 2011. At the end of October 2008, BHP Billiton announced that it expects to complete the first of the mines fivestage expansion by 2013, boosting annual production capacity to 200,000t of copper, 4,500t of uranium and 120,000oz of gold.
The Sierrita mine is a porphyry copper deposit that has oxide and secondary sulfide mineralization, and primary sulfide mineralization. The predominant oxide copper minerals are malachite, azurite and chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, and chalcopyrite and molybdenite are the dominant primary sulfides.
