Leaching was conducted in columns simulating dump leaching conditions. The leaching process consisted of applying a fixed volume corresponding to 7% of the ore weight of 200 g/l H 2 SO 4 to each column and then letting them stand for 1, 3, 5, 10, and 15 days. This allowed sulfation of copper from the different minerals to take place.
