High Temperature Thermal and Electrical Heating for Copper Extraction Pot

Case ID:
UA16-129
Invention:

This technology uses molten salts, which are electrically conductive and can be used as an electrolyte for the electrodeposition of copper, and extracts pure copper from impure copper inputs in a single step, therefore reducing the extraction time without requiring or producing any toxic products.

 

Background:
It is expected that around 6,000 metric tons of copper will be produced using solvent extraction/electrowinning methods by 2018. With the worldwide demand for copper rising, this technology has the potential to fill a need unmet thus far. The proposed device/technique extracts pure copper from a solution using one-step electrodeposition techniques involving molten salts, which create an environmentally friendly product/process that contains no toxic by-products.

 

Applications:

  • Copper refining

 

Advantages:

  • One-step process
  • Environmentally friendly
  • Does not require or produce any toxic products
  • Sustainable and economical for the user
