Natural iron oxides are derived from hematite which is a red iron oxide mineral limonites which vary from yellow to brown such as ochers siennas and umbers and magnetite which is black iron oxide Synthetic iron oxide pigments are produced from basic chemicals The three major methods for the manufacture of synthetic iron oxides are thermal decomposition of iron salts or iron compounds 06 30 32 The Brockman Iron Formation in the Hamersley province is the most significant host for high grade hematite iron ore deposit Magnetite is an iron oxide mineral that is generally black in colour and highly magnetic the latter property aiding in the beneficiation of magnetite or Magnetite contains 724 iron which is higher than hematite but the presence of impurities usually results in
