Latest Patents

Pia Sinisalo holds a patent for a method of recovering copper and precious metals. This method involves leaching copper-bearing ore and/or concentrate under atmospheric or slightly pressurized conditions at a temperature below the boiling point of the leach solution. The process utilizes a sulfuric acidic solution in the presence of one or more alkali metal or alkali earth metal halides, with a total halide concentration ranging from 30 to 115 g/L. The resulting leaching liquor contains copper, sulfur species, and halides in solution. Following solid-liquid separation, a first aqueous pregnant leach solution and a copper-depleted leaching residue are obtained. Copper is then purified through solvent extraction from the pregnant leach solution, leading to the recovery of copper.
