Ironrich rocks are common worldwide, but oregrade commercial mining operations are dominated by the countries listed in the table aside. The major constraint to economics for iron ore deposits is not necessarily the grade or size of the deposits, because it is not particularly hard to geologically prove enough tonnage of the rocks exist.
Jan 02, 2012· With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade 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.

1. Iron ore supply and demand outline Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron .
Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth''s crust.
Large numbers of iron ore mines are in operation in Orissa, India to meet the internal and export demand of iron ore for iron and steel making. During the process of mining relatively lower grade iron ore containing 5658% Fe is also being generated and stockpiled separately due to less market and industrial value. The accumulation of these
