Application of Ferrous sulphate as a mining chemical reagent.

Ferrous sulphate is green soluble coagulant that can be effectively used for waste water treatment. It is also effective in odour control, which it does by preventing the formation  of hydrogen sulphide.

With sodium cyanide use for gold cyanide being the preferred route for gold leaching, we are pleased to offer a product that restores harmony between you and your environment even after usage of cyanide.

Ferrous sulphate is used for detoxification of cyanide complexes in gold plant tailings before being channeled to the slimes dam.


It removes residual cyanide in the tailings aqueous solution by rendering it an immobile precipitate through the following reactions:

Fe2+ + 6CN- → Fe(CN)64-,

2Fe2+ + Fe(CN)64- → Fe2IIFeII(CN)6

The insoluble white ferrous ferrocyanide product rapidly absorbs oxygen from the air and turns deep blue, with the formation of ferric ferrocyanide

3Fe2IIFeII(CN)6 + O2+ 4H+→ Fe2III [FeII(CN)6 ]3 ↓ +2Fe2+ + 2H2O



Recommended Method of Application

Ferrous sulphate crystals are dissolved in cold water. The solution at a known concentration is kept in a container from where it is dosed at a rate that just detoxifies the residual cyanide. The optimal conditions for the detoxification reaction include a pH of between 5.5 and 6.5 as well as a Fe: CN ratio of  1:2.

Ferrous sulphate  other industrial uses include:


  1. Water Treatment
  2. Flocculant
  3. Coagulant
  4. Cyanide Neutralizer
  5. Remove COD
  6. Odor Eliminator
  7. Fertilizer
  8. Animal Feed Supplement
  9. Agriculture
  10. Paint Pigments
  11. Ferrites
