Applying Softcomputing for Copper Recovery in Leaching Process

The variability of the composition of copper leach piles makes it unlikely to obtain high precision simulations using traditional statistical methods; however the same data collection favors the use of softcomputing techniques to enhance the accuracy of copper recovery via leaching by way of prediction models. leaching in dynamic cells

The Dynamic and Leaching Study of Gold in Treated Sludge

Under the optical conditions, the leaching efficiency was up to 85.1%, while the dynamic behavior of gold leaching was studied, the activation energy of the system Eα=20.093kJmol-1, and reaction velocity constant k=4.084e-20093/RT. The treatment of copper sludge could greatly reduce the potential contamination to the environment.
