Ferrous sulfate is a commonly used reagent in gold processing plants for tailings treatment. Gold mine tailings often contain high levels of cyanide, which is highly toxic and hazardous. Therefore, even wastewater with relatively low cyanide content needs to be treated before discharge or reuse. Ferrous sulfate complexation is effective in cyanide removal. The ferrous…

Ferrous sulphate, also known as copperas, crystal of light blue or green. It can be used as flocculating agent, reducing agent, and precipitation agent for various kinds water treatment, not only obvious effect, but also cheaper.The purpose of Ferrous Sulphate: Ferrous sulphate is a strong reducing agent, it can transfer hexavalent chromium to trivalent chromic…
Ferrous Sulphate remove chromiumFerrous Sulphate can be used as reducing agent to decrease chromate in cement. In the process of cement production, 900 ppm of ferrous sulphate can make hexavalent chromium (Cr6+) decrease to 2 ppm. Chemical deposition:Formula: H2Cr2O7+6FeSO4+6H2SO4=Cr2（SO4）3+3Fe 2（SO4）3+7H2OProcesses: The harm of hexavalent chromium (Cr6+): In California, hexavalent chromium be provision that cannot exceed…
