  • Tailings Resolution Copper

    Tailings. The mining process involves separating the copper ore from noneconomic rock. After removal of the copper, what remains is called 'tailings.' Tailings include particles of rock, water, and residual process chemicals. We will pump the slurry-like tailings via a pipeline to a designated facility for permanent storage.

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden which is the waste rock or other

  • Economic Potential for reprocessing Copper Mine Tailings

    Four copper mine tailings in Chile were investigated for their elemental and mineral composition, in order to evaluate the potential for economic reprocessing. The sample material, taken for processing had Cu-contents between 0.1 and 0.5 %. Copper was abundant in various primary (mostly chalcopyrite) and secondary (cuprite, atacamite, b

  • Copper Ore Processing Methods

    The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
