    Chalcopyrite and molybdenite are the dominant primary sulfides and are the primary economic minerals in the mine. Chalcocite is the most common secondary copper sulfide mineral, and the predominant oxide copper minerals are chrysocolla, malachite and azurite.

  • Water Consumption at Copper Mines in Arizona

    and copper mining is no exception. Arizona is mostly desert and, therefore, short of water. This scarcity has been exacerbated because of the rapid growth of population in the state and the resulting enhanced demands for the resource. This has also attracted the attention of the general public to the use of water for mining.

  • Copper extraction - Wikipedia

    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).
