Abstract

See full text

Compositions and methods for treating waste water produced by copper mining operations are described herein. Slag from steel making operations and other industrial waste materials that include alkali metal and/or alkaline earth elements have been found to both raise pH of the waste water and also reduce arsenic content. Following such treatment the spent slag or industrial waste can be utilized as a source of valuable metals or incorporated into stabilized building materials.
