Water Reclamation and Tailings. The concentrated ore, now called copper concentrate, is dewatered and dried to about 10% moisture content. It is shipped by truck to the Asarco smelter in Hayden, Arizona. (The El Paso smelter is on standby status). Water is recovered from the tailings in another thickener.
opper Mining and Processing MODULE SUMMARY Copper is a chemical element that has a variety of uses based on its properties of malleability and conductivity. Copper ore deposits are found on every continent, and it has been mined around the world for more than 10,000 years. It is a necessary component for many products in the modern world.

Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and ...
