Assuming an ore grade of 0.55 percent and a recovery rate of87.5 6.4 percent copper in the concentrate, concentrat-ing 1 ton of copper ore requires over 200 billion Btu, or approximately 42 million Btu/ton of cath-ode copper.10 Grinding accountsfor roughly 6 0 percent of the total energy consumed in proc-essing, and crushing 12 percent. Pumping new and recycled water,

  • Energy and Environmental Profile of the U.S. Mining Industry 5

    Copper beneficiation may consists of: crushing and grinding, washing, filtration, sorting and sizing, gravity concentration, flotation, roasting, autoclaving, chlorination, dump and in situ leaching, ion exchange, solvent extraction, electrowinning, and precipitation. Crushing and grinding is the most energy intensive.

  • Energy Consumption in Mining Comminution ScienceDirect

    1/1/2016· The world’s biggest copper companies use concentration plants, which are energy intensive and use the world’s biggest pumps in their main production process. The distribution of energy at a mine site is 3 – 5% for blasting, 5 – 7% for crushing, and 80 90 % for grinding [10, 11].

  • How Hydrometallurgy and the SX/EW Process Made

    In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.

    ore from larger size, say 0-1000 mm down to 0-250 mm. The primary crushing op-eration is done either in underground mines or surface mines. This is followed by a secondary crushing station usually at surface mines, where crushing machines such as cones crushers are used to further reduce the hard ore from 0-250mm down to less than 70 mm.
