  • How phosphate is mined and processed

    Sulfuric acid production creates a lot of heat. This heat is used by a power plant to generate electricity, which helps to power both sulfuric acid production and phosphoric acid production. The mixing of sulfuric acid and phosphate creates gypsum (called phosphogypsum) as a byproduct. Although gypsum can be used for a variety of purposes, the

  • Acid Mine Drainage

    When iron sulfide is exposed to air or dissolved oxygen in water, the sulfide oxidizes to sulfate, which then turns to sulfuric acid (H2SO4). Sulfuric acid is a highly corrosive chemical, used in many industrial processes as well as in car batteries. It is also one of the primary constituents in acid rain, and is toxic to most living organisms. The sulfuric acid produced in sulfide mine tailings makes the surrounding water
