glutenite copper ore

     

producing cathode copper from refractory glutenite copper ore, which falls under the technical field of metallurgy.

This method prepares cathode copper by subjecting the refractory glutenite copper ore to sequential processes: crushing and granulation, curing treatment, heap leaching, solvent extraction and electrowinning. Prior to the heap leaching process, raw ore particles are treated with sulfation curing pretreatment. The pretreatment not only enables copper to be dissociated from gangue and other associated minerals, but also achieves the effect of loosening the ore structure and increasing its porosity, which facilitates the heap leaching process, raises the leaching rate by 10% to 20%, and creates favorable conditions for subsequent cathode copper production.

The cathode copper produced by this method features high purity and large output. The method effectively improves the copper leaching rate and recovery rate of refractory glutenite copper ore, realizes more efficient utilization of mineral resources, and boosts economic benefits.
