Leaching and Electrowinning Copper from Oxide Copper Ores

     

Hydrometallurgical Process for Leaching and Electrowinning Copper from Oxide Copper Ores:

Process Description:

The process involves heap leaching copper oxides using sulfuric acid (H2SO4). After leaching, the resulting pregnant solution is neutralized with a base (e.g., NaOH) to precipitate copper as copper hydroxide (Cu(OH)2), which is then filtered and dissolved in sulfuric acid again to form a copper sulfate solution.

The copper sulfate solution undergoes leaching-electrowinning operations, including solvent extraction and electrorefining, to produce cathode copper.

Advantages of the Process:

In-situ Leaching: This method allows for the treatment of disseminated oxide copper ores that are difficult to process otherwise.

Concentrated Leaching-Electrowinning: By centralizing leaching and electrowinning operations, the process reduces transportation costs as it transitions from ore transport to tailings transportation.

Cost-Effectiveness: The process minimizes capital investment while achieving high efficiency in copper recovery.

Economic and Environmental Benefits: Reduces the need for ore transportation, lowering environmental impact and operational costs.
