Free Extraction And Processing Of Copper Essay

Aurubis pushing for copper recycling in the circular economy The steadily growing demand for copper is prompting concerns around how this demand can be met in the most sustainable way and different parts of the mining and metals industry are responding to this challenge in various ways The circular economy – the idea of keeping resources in use for as long as possible and recovering.Additionally leaching rates of copper from the magnetic concentrates and tailings were recorded as 28 44 and 26 95 respectively In summary the proposed methods by Kunming University of Science and Technology scientists proved efficient for copper recovery energy saving and adaptability Copper recovery was enhanced up to 87 61.
