    1/15/2019· In this study, high voltage pulse breakage was used to study the breakage process of copper ore. The particle size, shape coefficient and preferential crushing index (Δ α i) were determined using systematic experiments.The parameters were further investigated by fitting the energy consumption model of breakage to the experimental data.

  • Copper extraction Wikipedia

    Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of 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. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper

  • Particle damage and exposure analysis in HPGR

    10/1/2011· Copper ores (copper oxide ore and copper sulfide ore) were crushed by a jaw crusher and by HPGR. Crushed and sized products were evaluated for particle damage and copper grain exposure by X-ray computed tomography. Column leaching was done to determine the rate and extent of copper recovery. HPGR crushed products have more particle damage and higher copper recoveries. Copper recovery from the copper

In addition, copper is a base metal; its ores often contain other elements such as gold, silver, molybdenum, cobalt, and selenium [5], which makes copper mines an important source for these by-products [6,7]. However, the amount of primary copper is limited and the quality, i.e., the ore grade of the resources, varies.
