faq about copper ore processing,Florence Copper Frequently Asked Questions, FAQ'sThe Florence Copper project is not a copper mine in the traditional sense of the term but rather an in-situ (in place) recovery project that dissolves copper from underground bedrock ore using a process that was developed and executed safely decades ago for all types of mineral extraction. The project has received a permit.faq about copper ore processing,How can metal mining impact the environment? | American .Waste piles from processing, such as tailings impoundments, leach piles, and slag piles vary in size, but can be very large. The impoundments associated with some of the largest mills, such as at open pit copper mines, can cover thousands of acres (tens of km2) and be several hundred feet (about 100 m) thick. Heap leach.
