Siderite FeCO3 Extraction of Iron A mixture of oxide ores of iron (Fe3O4 and Fe2O3) is used to extract pure iron. Concentrating the ores Jaw crushers are used, and the ore is broken into smaller pieces. Concentration is carried out by the gravity separation process. Clay, sand, etc., are removed by washing it with water.
