The Use of Waste Gypsum The Use of Waste Gypsum

Farmers can use waste gypsum that complies with SEPA’s April 2010 Gypsum Position Statement (which includes a requirement to meet the PAS 109:2008 specification) as a soil conditioner without having to register the end use with SEPA But each farm has to be clear what this entails and ensure that the gypsum is not allowed to mix with organic wastes during storage or applicationGypsum is the waste product of this reaction Approximately 5 tons of gypsum are produced for every ton of phosphoric acid produced [2] Brazil was Evaluation of the Use of Waste Gypsum from theEvaluation of the Use of Waste Gypsum from the MiningAbstract: Disposal of waste in the metallurgical industry has become a challenge Heaps of gypsum from hydrometallurgical plants using sulphates media are growing and pose an environmental problem The current investigation focuses on the use of disposed gypsum from hydrometallurgical plants for Nickel recovery from slag Sulfurization tests were carried out at different temperatures ranging from 600⁰C to 1250⁰C XRD, XRF, ICPMS and SEMEDS were usedUse of Waste Gypsum from Hydrometallurgical Plant for
