Product Description
Copper Leaching Plant
Introduction
The Copper Leaching Plant is a comprehensive solution designed for the efficient extraction of copper from copper oxide and sulfide ores. This plant integrates advanced leaching, solvent extraction, and electrowinning technologies to maximize copper recovery rates while minimizing operational costs.
Key Features
-
High Recovery Rate: Achieves copper recovery rates of up to 99.99% through advanced leaching and extraction processes.
-
Integrated Process: Combines leaching, solvent extraction, and electrowinning in one system, reducing the time copper stays in the process and improving overall efficiency.
-
Energy Efficient: Designed to minimize power consumption, making it cost-effective for both small and large-scale operations.
-
Environmentally Friendly: Uses minimal chemicals and ensures proper waste management, meeting environmental regulations.
Main production process introduction:
leaching
Heap Leaching: Crushed ore is piled up in heaps, and a leaching solution, usually sulfuric acid, is applied over the heap. The solution percolates through the heap, dissolving the copper from the ore as it moves downward. Agitation Leaching: In some cases, the ore is placed in tanks, and the leaching solution is agitated to improve contact between the solution and the ore. This method is faster but requires more controlled conditions.
Solvent extraction
The copper-laden leach solution, called pregnant leach solution (PLS), is then subjected to solvent extraction. In this process, an organic solvent selectively binds with the copper ions, separating them from other impurities in the solution. The copper is transferred from the aqueous phase to the organic phase. The remaining solution, called raffinate, is often recycled back to the leaching stage.
Electrowinning (EW)
The copper-rich organic solution is then mixed with an aqueous solution in a stripping stage, where copper ions are transferred back into an aqueous phase called the electrolyte. In the electrowinning process, an electric current is passed through the electrolyte in an electrochemical cell. Copper ions are reduced and deposited onto stainless steel or copper starter sheets, forming high-purity copper cathodes.
Cathode Harvesting
The copper cathodes, which are typically 99.99% pure, are periodically harvested from the electrowinning cells. The sheets are removed, washed, and prepared for sale or further processing.
