  • Kennecott Utah Copper-Sustainable Over Time PHOTOS/VIDEO AUDIO
    1 UNIVERSITY OF UTAH DEPARTMENT OF MINING ENGINEERING PRESENTATION to IMOA by Louie Cononelos “Kennecott Utah Copper-Sustainable Over Time PHOTOS/VIDEO AUDIO This is a story that had its beginning over 150 ago…and that story is still being written today. It began in Bingham Canyon, Utah located about 26 miles southwest of Salt Lake City, which was destined to become one of the greatest “mining camps” anywhere in the country. Mining in Utah, which was part of Spanish Mexico, can be traced back to Spanish miners in the mid-1700s. The start of mining in Utah, however, is credited to the United States Army in 1863. Troops under the command of Colonel Patrick Connor are credited with the discovery of Utah’s first mining claim and helping to form the first mining company and mining district in Bingham Canyon. The early mining at Bingham was underground with the exception of placer mining. 2 Bingham Canyon was a beehive of mining activity at the turn of the Century. Dozens of small companies dug tunnels and sank shafts in the mountains where they were mining lead, silver and gold ores…but not the low- grade copper ores that were in abundance and considered a nuisance. Then, along came Daniel C. Jackling, a 29-year-old metallurgical engineer, who with his partner, a mining engineer named Robert Gemmell, studied and assayed ore samples from the operations that dotted the canyon. They determined that there were vast tonnages of low- grade copper ore in the main mountain that divided the canyon…it was the kind of ore the mining companies tried to avoid because it interfered with the recovery of the metals they were mining.

The Manefay Slide has been called the largest non-volcanic landslide in modern North American history, as it is estimated it displaced more than 145 million tons of material. No injuries or loss of life were recorded during the incident; however, the loss of valuable operating time has a number of slope stability experts wondering how to prevent future large-scale slope failure in open pit mines. This comprehensive study concerns the analysis of the landslide at Bingham Canyon Mine and the mitigation of future, large- scale slope failures. The Manefay Slide was modeled into a two- dimensional, limit equilibrium analysis program to find the controlling factors behind the slope failure. It was determined the Manefay Slide was a result of movement along a saturated, bedding plane with centralized argillic alteration.

  • Reuse and the Benefit to Community: Kennecott South Zone Superfund Site
    Reuse and the Benefit to Community Kennecott South Zone Introduction Mining has long been a way of life in and around Utah’s Bingham Canyon. Few ore deposits in the world have been more productive than those found at Bingham Canyon Mine. The mine has produced millions of tons of copper and tons of gold and silver. Mining operations also contaminated soil, surface water and groundwater in the surrounding area, referred to by regulators as the Kennecott South Zone (the site). During cleanup discussions, the site’s potentially responsible party, Kennecott Utah Copper, LLC (Kennecott), proposed a course of action that would address contamination while avoiding placing the site on the Superfund program’s National Priorities List (NPL). This approach was the template for the Superfund Alternative Approach, which has since been used at sites across the country. EPA approved the cleanup plan, setting the stage for the site’s cleanup and remarkable redevelopment. Open communication, extensive collaboration and innovative thinking helped contribute to the transformation of this once contaminated, industrial site into a thriving residential area and regional economic hub. Superfund site restoration and reuse can revitalize local economies with jobs, new businesses, tax revenues and local spending. Cleanup may also take place while active land uses remain on site. This case study focuses on the Kennecott South Zone, primarily on operable unit (OU) 7 and an area known as the Daybreak development, which includes and surrounds OU7. Today, OU7 and several other parts of the site support a wide range of commercial, industrial, public service, residential and recreational reuses.

  • 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.

  • Hardrock Mining in Utah
    HARDROCK MINING IN UTAH In 2007, Congress will be considering changes to the antiquated Mining Law of 1872 that governs how gold, silver and other ‘hardrock’ minerals are developed on our National Forests and national resource lands administered by the Bureau of Land Management. Here are some nuggets on mining in Utah. Mining Activities As of 2006 mining interests have staked more than 1,480 active mining claims in Utah, covering an estimated 367,244 acres. The five Utah counties with the most acres claimed on the public lands are: Emery County - 64,605 acres, Beaver County - 59,969 acres, Tooele County - 32,449 acres, Millard - 26,252 acres, and San Juan County - 20,825 acres In 2006, there were 10 active or intermittent hardrock mining operations in Utah, employing 1,402 on site, according to the Mine Safety and Health Administration, representing 0.12% of the total employment in the state of Utah.

In 1988, Kennecott Utah Copper upgraded its air-fuel burners to low NOx oxy-fuel burners in its Utah Copper smelter-copper anode furnaces. This project resulted in energy savings of about 55 percent and substantial NOx emission reductions. When Kennecott APPLICATIONS designed its new, state-of-the-art smelter in the early 1990s, it selected oxy-fuel burners for the anode furnaces to achieve low NOx emissions and high energy Experience has shown that retrofitting efficiency. When oxy-fuel burner technology improvements became available in copper smelting anode furnaces from April 2000, Kennecott initiated another project to upgrade to a new design. air-fuel to oxy-fuel burners typically Switching to Dilute Oxygen Combustion (DOC) burners resulted in an additional results in substantially reduced NOx 80 percent reduction in NOx emissions, and improved maintenance costs for the two anode furnaces. emissions as well as 50 to 60 percent fuel savings from eliminating the large Plant/Company Overview nitrogen load associated with air-fired Kennecott Utah Copper, a subsidiary of the international mining and processing combustion.

  • John-Sebastien Jacques Chief Executive Officer Rio Tinto and Utah Kennecott Copper Corporation
    August 26, 2020 An Open Letter to: John-Sebastien Jacques Chief Executive Officer Rio Tinto and Utah Kennecott Copper Corporation Dear Mr. Jacques: As residents, and civic groups, of the Salt Lake Valley concerned for the health of all residents, we request that Rio Tinto Kennecott place its extensive land holdings in Salt Lake City’s Northwest Quadrant into a permanent conservation easement. Preserving this land would enhance the Kennecott Inland Sea Shorebird Reserve and demonstrate a commitment to public health and environmental sustainability. You currently plan to allow development of this land as part of an inland port. By protecting this area from development, Rio Tinto Kennecott would safeguard our valley from 70,000 additional daily commercial truck trips and 150,000 additional daily private car trips which our modeling suggests would be generated at full build out. Damage to water quality and important wildlife habitat is almost inevitable. Communities near inland ports elsewhere in the United States have suffered serious public health problems. Multiple studies of communities with inland ports elsewhere in the United States cite increases in numerous adverse health outcomes, including heart and lung disease, neurologic disorders, and increased cancer risk. As is the case with much urban environmental degradation, public health impacts fall disproportionately on low-income families and persons of color. Rio Tinto Kennecott’s long history of harming Utah’s environment has required numerous legal actions to end polluting activities. For decades, your operations in western Salt Lake County generated toxic selenium and arsenic groundwater plumes. An acid plume at the southern end of these operations rendered the water undrinkable for thousands of residents of South Jordan.
