  • Consequences of fractal grade distribution for bulk sorting of a

    Pod ore sorting, where batches of crushed rock are diverted based on copper grade, is one potentially high impact technology to address dropping head grades in copper deposits. To date, sorting of crushed ore has generally taken place at low rates on a rockbyrock basis (Salter and Wyatt, 1991). For pod sorting to be

  • Copper Mining and Processing: Processing of Copper Ores

    The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper.
