Process for the recovery of iron as hematite and other metallic values from a sulphate leach solution

February 18, 2016

SUMMARY

We propose a method for recovering iron from ferric sulphate solutions, obtained from leaching of metal bearing materials with sulphuric acid to produce an iron bearing leach solution, in the form of oxide as a useful product by precipitation as hydroxide, by subsequent pressure oxidation, and then by calcining of the iron hydroxide.
