Salt Lake City, Utah

Our Kennecott mine is a world-class, integrated copper mining operation located just outside Salt Lake City, Utah, in the United States. Kennecott has been mining and processing minerals from the rich ore body of the Bingham Canyon Mine since 1903, and is even today one of the top producing mines in the world. Our operation also includes a concentrator, smelter and refinery.


Reducing our Carbon Footprint

In 2019, after 75 years of operation, Kennecott retired its coal-fired power plant in Magna, Utah. Power for the operation will come from renewable energy certificates purchased from Rocky Mountain Power – primarily from wind and solar resources.

Closing the plant and acquiring renewable energy certificates will remove more than one million tons of carbon dioxide every year from Kennecott’s Wasatch Front operations, reducing its annual carbon footprint by as much as 65%.

The renewable energy certificate program is Green-e Energy certified, and meets the environmental and consumer-protection standards set by the Center for Resource Solutions.

Improving Energy Efficiency

At Kennecott, we continue to look for new ways to improve energy efficiency and increase our on-site-generated power supply. The $10 million, 6.2 MW combined heat and power (CHP) system – large enough to power 6,000 average-sized homes – is one example of how we are doing this: Generating enough power to supply up to 50% of the electrical needs of the refinery.

CHP, also known as cogeneration, is an efficient, clean and reliable way to generate power from a single fuel source.

Growth

Since 2011, we have spent more than one billion to deepen the south wall of the mine to expand our operations.

Kennecott’s South Pushback project is our plan to extend the life of the mine to 2032. The plan includes “pushing back” the south wall to reach additional copper ore to meet the growing global demand.

Environment

Kennecott has transformed acreage once dominated by over-grazed lands, salt evaporation ponds and illegal dumps into a 3,670-acre shorebird and waterfowl reserve along the south shore of Great Salt Lake.

In 1996, we helped to create the Kennecott Inland Sea Shorebird Reserve (ISSR) under a mitigation plan and today, the reserve is one of the largest and most successful mitigations in the United States. The number of bird species using the reserve area has gone from 50 in 1995 to 200 – a 300% increase – and today, approximately 120,000 birds use the reserve every year.

Kennecott Communities

Our commitment to making a positive impact in the communities in which we operate – and where so many of our employees live – is an important part of how we do business. For example, we have been working with the Natural History Museum of Utah for more than 40 years on award-winning science education programs, community enrichment initiatives and exhibits about the natural world. In 2008, we donated copper, which today, adorns the outside of the Museum’s home at the Rio Tinto Center.
