Increasing iron ore demand, coupled with the depletion of high grade hematite ores in the United States, led after World War II to development of lower grade iron ore sources, principally the utilization of magnetite and taconite. Iron ore mining methods vary by the type of ore being mined.
Approximately 96% of Australia39;s iron ore exports are high grade hematite, the bulk of which has been mined from deposits in the Hamersley province of Western Australia. The Brockman Iron Formation in this province is the most significant host for high grade hematite iron ore deposits.

Understanding the dynamics of the high grade iron ore market starts with appreciating the wide variety of product types that make up this segment. In this first section, we outline the different chemistries and physical forms of products that make up distinct categories within the high grade iron ore market. Grade
Low grade iron ore, defined as containing between 20 and 47% iron, is thought to be the primary iron bearing lithology from which most high grade ore deposits formed, through different processes of enrichment. . The beneficiation products are suitable for use in iron and steel making processes.
