The main environmental impacts associated with plasterboard result from the production process, transportation and disposal.

  • By Donald W. Olson USGS Mineral Resources Program

    gypsum generated by domestic coalfired electric utility FGD systems was used, compared with 19% in 2000. Of this 25.8 Mt total of synthetic gypsum generated, 5.65 Mt of the synthetic gypsum generated during the year was used for wallboard production, 471,000 t of the synthetic gypsum was used in

  • Gypsum Wikipedia

    Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ܨH 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard chalk and wallboard.

  • Chemicals Used in Mining Hesperian Health Guides

    Chemicals used in mining and processing minerals contaminate the land, water, and air, causing health problems for workers and people living near mines. Toxic chemicals used in mining include: cyanide, sulfuric acid, and solvents for separating minerals from ore nitric acid ammonium nitrate and fuel oil ("ANFO") used in blasting tunnels

  • Gypsum Mineral Uses and Properties

    Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

  • Properties and Uses of Gypsum ScienceStruck

    Mining of gypsum is simple and easy, as the mineral occurs in large thick beds near the Earth's surface. However, largescale mining of gypsum involves considerable damage to the environment. Gypsum can also be recycled, but not much importance has been given to recycle this mineral due its abundance.

  • gypsum Definition, Uses, & Facts Britannica

    Gypsum plaster is a white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added. Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water.

  • Chemical Processing of Phosphate Florida Industrial and

    Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used
