This reprint is tightly related to minerals engineering. The solution mining (heap leaching, in situ leaching, etc.) offers an environmentally friendly, low-cost, and efficient method to extract these minerals, especially copper sulfides (chalcopyrite, chalcocite, etc.), sandstone uranium, and sands...
