It is made of copper, iron, and sulfur. It is a brassy yellow, metallic mineral and it is very heavy. Chalcopyrite is not as hard as pyrite, which is called fool’s gold. Chalcopyrite will not scratch glass, but will scratch a copper penny. Pyrite will scratch glass. Chalcopyrite is also a brighter yellow than pyrite. It often tarnishes to a blue-green, iridescent color on weathered surfaces. Chalcopyrite is the main copper sulfide ore. Chalcocite Bornite is also known as Peacock Copper because of the blue-green tarnish. On freshly broken surfaces, it is Chalcocite is a sooty black, bronze colored. -
Failure to Capture and Treat Wastewater
U.S. OPERATING COPPER MINES: FAILURE TO CAPTURE & TREAT WASTEWATER BY BONNIE GESTRING, MAY 2019 In 2012, Earthworks released a report documenting the failure to capture and treat mine wastewater at U.S. operating copper mines accounting for 89% of U.S. copper production.1 The report found that 92% failed to capture and control mine wastewater, resulting in significant water quality impacts. This is an update to that effort. We reviewed government and industry documents for fifteen operating open-pit copper mines, representing 99% of U.S. copper production in 2015 – the most recent data on copper production available from the U.S. Geological Survey (see Table 1). Our research found similar results: 14 out of 15 (93%) failed to capture and control wastewater, resulting in significant water quality impacts (see TaBle 2). These unauthorized wastewater releases occurred from a number of different sources including uncontrolled seepage from tailings impoundments, waste rock piles, open pits, or other mine facilities, or failure of water treatment facilities, pipeline failures or other accidental releases.

Water Consumption at Copper Mines in Arizona by Dr
Water Consumption at Copper Mines in Arizona by Dr. Madan M. Singh State of Arizona Department of Mines & Mineral Resources Special Report 29 December 2010 State of Arizona Jan Brewer, Governor Phoenix, Arizona ARIZONA DEPARTMENT OF MINES AND MINERAL RESOURCES Dr. Madan M. Singh, Director 1502 West Washington Phoenix, Arizona 85007 602 771-1600 Fax 602-771-1616 Toll-free in Arizona – 800-446-4259 www.mines.az.gov Board of Governors R. L. Holmes - Phoenix Chairman P.K. Medhi - Casa Grande M.A. Marra - Phoenix Secretary Member L.H. White - Phoenix Member WATER CONSUMPTION AT COPPER MINES IN ARIZONA Arizona has the best copper deposits in the United States, and produces more of the red metal than most countries except Chile and Peru. All mining needs water for mining and processing and copper mining is no exception. Arizona is mostly desert and, therefore, short of water. This scarcity has been exacerbated because of the rapid growth of population in the state and the resulting enhanced demands for the resource. This has also attracted the attention of the general public to the use of water for mining. Most water is used in flotation beneficiation, smelting, and electro-refining. Small amounts are used for domestic purposes (drinking, bathing, and such). It is also used for wetting roads to suppress dust. Factors affecting dust suppression include annual precipitation, natural vegetation, land morphology, and other factors. The amount of water used for wetting may vary between 0% and 15% of the total water used at the mine, depending on conditions. The water source may be from underground aquifers, Central Arizona (CAP), surface streams, precipitation, or a combination. -

Mining Reclamation in North America
MINING RECLAMATION IN NORTH AMERICA Supporting A Sustainable Future The reclaimed Galena stockpile in Bisbee, Arizona, reflecting new vegetation growth in 2012. As a premier natural resource company headquartered in Phoenix, Arizona, we operate large, long- lived, geographically diverse assets around the world. In North America, our mining operations are in Arizona, Colorado and New Mexico. We operate seven open-pit copper mines in the United States – Morenci, Sierrita, Bagdad, Safford and Miami in Arizona, and Tyrone and Chino in New Mexico. In Colorado, we conduct molybdenum mining operations at the Henderson underground mine and the Climax open-pit mine. We produce metals to meet society’s needs with a commitment to sustainable development, part of which includes the land reclamation process. This process involves taking land once used in mining operations and converting it into alternate land uses. With an eye toward the future, we focus on sustainable development today as a common thread that runs through all that we do.
