oxide ore sulphide


What is the best method for sulfide copper leaching?

A low grade sulphide ore leaching could be contemplated using an oxidative / bacterial heap leach. Another option is to concentrate the sulphides using flotation, then atmospheric or pressure leaching with oxygen to solubilise the copper. Roasting to remove the sulphur and oxidise the copper for acid leaching is also an option. …
