  • Copper extraction

    Most copper ores contain only a small percentage of copper. The remainder of the ore consists of gangue of no commercial value. Gangue from copper mining typically contains silicate mineralsand oxides. In some cases these tailings have been retreated as the technology for recovering copper has improved. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals including copper being less than 2% of the total volume of the ore rock. A key o

    Flotation is widely used to concentrate , lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation .

  • Hot water separation process for copper and insulating

    Abstract. Recycling in the electric cable industry, especially the complete separation of metal and insulating material for reuse, has always been a problem. The present processes to recover copper and insulating material from cable waste involve the grinding of cables into smaller pieces to improve metal liberation from the insulating material. The method results in fine thread-shaped metal wedges in the
