zimbabwe research on efficiency of hematite iron ore

Jan 02, 2012· With the depleting reserves of high-gradeiron orein the world, frothflotationhas become increasingly important to process intermediate- and low-gradeiron orein an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in theiron oreindustry, frothflotationhas been established as anefficientmethod to remove impurities fromiron ore.
