The other is to reduce the sulfur content via the iron ore beneficiation process As a sorting process, flotation plays a fundamental role in this The objective of the test campaign described below was to reduce the sulfur content in an iron ore concentrate from 13 % to less than 04 %
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led 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
iron ore, which greatly affects the price of iron ore concentrate Moreover, high contents of sulfur in steel decrease its quality In addition, the presence of sulfur in iron ore concentrates causes environmental issues, especially sulfur dioxide emissions during the pelletizing or smelting process
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore
