Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Sulfuric acid injection in copper heap leaching | LEWA

Following mining, transporting and crushing to a consistent gravel-size, the ore is piled into a heap on top of an impenetrable layer on a slight slope. The leaching reagent (dilute sulfuric acid) is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore.
