  • In-Situ Leaching & Borehole Mining

    Jan 14, 2019· In Situ Leaching Copper . The leaching portion of the in situ mining program (particularly for copper) is divided into three broad depth ranges: surface, near surface, and deep (fig. 1). Most of the copper ore bodies in the surface category are above the water table, and little, if any, overburden covers the ore.

  • 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

    May 23, 2017· PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

  • Innovations Copper

    With in situ mining, a diluted sulfuric acid and ferric sulfate solution is injected down holes drilled into the ore body. The solution flows through cracks in the rock under pressure, leaching the copper from the rock into the solution. The solution is then pumped to the surface to recover the copper, using solvent extraction techniques.
