What happens to the waste from copper mine leach pads?
Waste generated from copper leach fields often undergoes a variety of treatments and processes before being properly disposed of.
A common approach is to confine waste to landfills, which are lined with impermeable material to prevent any leaching or contamination of surrounding soil and water sources.
Another common method of waste disposal is to incorporate it into tailings. Tailings are essentially the residue left behind after ore processing and extraction of valuable metals. By adding leach pad waste to the tailings, the overall amount of waste can be reduced and the remaining material consolidated into one location.
Both methods are effective in safely and responsibly treating waste generated from copper mine leach pads. While mining operations certainly pose environmental concerns, today's modern mining practices are designed to minimize impacts on surrounding ecosystems and natural resources.
