Since the middle of the 1500 s, mining has been active in central Mexico. Total estimates for low-grade piles and mine tailing materials in the Guanajuato mining district (GMD) are in the range of 150 million tons, covering an area of 15 to 20 km². GMD is located in the Guanajuato River sub-basin (GRB), which is part of one of the largest basins in...
