Neumann Systems to Extract Rare Earth Metals from Flyash
Outside the Ray Nixon Power Plant south of Colorado Springs sits 3.3 million tons of coal ash the remnant of three decades of coal-fired power generation. Nationwide, 20 percent of flyash, is recycled into concrete. However, since the 80,000 to 100,000 tons of flyash produced each year by Colorado Springs Utilities’ two coal-fired power plants doesn’t consistently meet construction industry standards, it collects in a landfill that grows by hundreds of tons every day.

FGD and New Plant Projects at Southern as of July 30, 2012
Southern Co. said on July 25, 2012 that it plans to shut down about 4,000 MW of older coal-fired power plants, to continue operating 13,000 MW of coal-fired power plants, and to switch about 3,000 MW to run on low-priced natural gas from other fuels. Southern said it expects to spend nearly $1 billion less than previously planned on pollution-control equipment at its coal-fired power plants, thanks to changes that the Environmental Protection Agency made to its final rules limiting mercury and other emissions from coal-fired power plants. The changes provided utilities with more flexibility in the ways they can meet the new limits. Southern said it now expects to spend about $1.8 billion on pollution controls from 2012 through 2014.
