were absent after bioleaching. Free copper oxide and copper silicates could be leached out easily by using JAT-1; a small part of the copper sulfide can also be leached out. Bioleaching using JAT-1... such as simple operation, low operating cost, low energy input and friendly towards the environment [1, 2]. There are many studies related to the bioleaching of sulfide copper ores with autotrophic......

/mineral[11], so researching the surface morphology changes can help us to reveal oxidation mechanism of bio-oxidation. Chalcopyrite is the most common copper sulfide in the copper-nickel ores...-oxidation. The purpose of this work is to show the characteristics of dynamic corrosion of the typical copper-nickel sulfide mineral pairs from the microscopic point of view. The mechanisms in bio......
