• Copper Concentrates - Cargo Handbook - the world's

    DescriptionApplicationShipment / StorageRisk FactorsCopper extraction techniques refers to the methods for obtaining copper from its ores. This conversion consists of a series of chemical, 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). To do this, the ore is crushed then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it und
  • Copper Concentrate - an overview ScienceDirect Topics

    The pulp from this grinding process is introduced into a floating process to which water and chemical reactants are added. This process results in a collective concentrate, Cu-Mo, containing approximately 30% copper and 1% molybdenum. In a follow-up process, the copper and sulfur-molybdenum concentrate are separated.

  • Copper Concentrate Enrichment Process

    2020-6-22  Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps. Some ores have associated problems such as chalcocite-coated pyrite and are difficult ...
