Aug 01, 2012 A new method to recover iron from high iron-bearing zinc calcine was developed. Zinc ferrite (ZnFe 2 O 4) in zinc calcine was decomposed to zinc oxide and magnetite after roasting under a reducing atmosphere at temperatures over 700 C.A mineral dressing by magnetic separation was used to recover magnetite from the roasted products.
