Toxic chemicals used in mining

Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.
