  • Gypsum: an old product with a new use | Integrated Crop

    Gypsum is used to add large amounts Ca 2 + ions that displace the Na+ ions from the exchange sites, and when flushed with clean water both salts and Na are removed from the soil (gypsum is used instead of limestone because of higher solubility and no increase in soil pH). However, even in these sites this practice is not effective when subsoils have low permeability to water. If a soil onlyОнлайн-запрос

  • Production of gypsum products from waste battery acid

    A new innovative process in which the waste sulphuric acid (H2SO4) from the batteries is neutralised with the aid of either calcium hydroxide (Ca(OH)2) or calcium carbonate (CaCO3) will produce gypsum (CaSO4.2H2O), a valuable product in plasterboard and cement production. The suitability of the gypsum produced depends greatly on the purity, crystal shape, crystal size and moisture content.
