Electrochemical Pretreatment of Chrysocolla for Enhanced Sulfidization and Flotation: Mechanism and Process Optimization

The flotation of oxidized copper minerals is limited by poor surface reactivity and the insufficient effectiveness of conventional sulfidization. This study investigated 50 Hz alternating current electrochemical pretreatment to enhance the sulfidization and flotation of chrysocol...

Comparative Study of Hydrometallurgical and Pyrometallurgical ZnO Recovery from Mixed Metallurgical Sludge

The recovery of zinc from mixed steelmaking and blast furnace sludge was investigated through a direct comparison of the hydrometallurgical acetic acid leaching process and pyrometallurgical processing using coke dust as a reductive agent, with particular emphasis on the structur...
