Particle damage and exposure analysis in HPGR crushing
2011年10月1日 Highlights 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

Copper processing - Ores, Mining, and Refining Britannica
Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in
