    Copper Mine Leaching Skyline Dredging Amp Excavating

    This redesign ushered in a new era for leaching copper. Skyline Dredging amp Excavating was able to lay 8 hoses in 5 minutes for the leaching of copper at the Phelps Dodge Morenci Copper Mine, located in Morenci, AZ. This new method provided a significant reduction in cost as well as a much safer method within their leaching division.

  • Copper Mining and Production Processes Explained

    Copper Mining And Production Processes Explained

    Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW solvent extractionelectrowinning.

    Low-grade ore is ball-milled before being agglomerated and dump-leached to recover its copper content. The Detroit Copper Company started mining at Morenci, 16km south of Silver City, Arizona, in 1872. Copper Queen Consolidated Mining bought the property in 1885, with the company name changed to Phelps Dodge in 1917.
