Toxic chemicals used in mining - Impacts of mining at ,
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 lead ore concentrate from the flotation tanks now contains about 50% lead and ca 01% of silver, a relatively small but valuable amount (b) Smelting Smelting is usually a two-stage process as described here, although single-stage methods with lower energy use and emissions are also used..
