Mechanochemical leaching of chalcopyrite concentrate by

This study aimed to introduce a new cost-effective methodology for increasing the leaching efficiency of chalcopyrite concentrates at ambient temperature and pressure. Mechanical activation was employed during the leaching (mechanochemical leaching) of chalcopyrite concentrates in a sulfuric acid medium at room temperature and atmospheric pressure. High energy ball milling process was usedTurn-Key Ore ProcessorTurn-Key Ore Processor. The jaw crusher, hammer mill and fine gold shaker table form the heart of the basic ore processor system. They are integrated into a turn-key unit by installing them into structural frameworks, linking them with hoppers, feeders and conveyors, and wiring them, ready for connection to a power source and water source.Mining & Minerals ProcessingLeaching Classification Coarse Flotation LIMS DWD RED RED Similar to the equipment used in wet processes, Eriez uses drum, roll, pulley and filter type magnetic separators in varying degrees of intensity to process dry minerals.
