Alumina levels range from 59 to 88 in the feed material and will be reduced to 28 after processing The plant will also remove clays from the feed material and the combined effect will see the Fe content increase from between 434 and 527 in the feed to nominally a 60 iron ore product accounted for a increase in the content of iron and a con siderable reduction in the SiO2 content in the iron con centrate while the recovery of the mass and of Fe fell It is important to add a depressant agent to the iron mi nerals in the iron ore reverse flotation In this work corn starch and CMC carboxymethylcellulose were used

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 A trend of reducing the iron grade and of course increas levels of conta ing minants is observed in itabirites tailings in the Quadriltero Ferrfero Minas Gerais state Brazil Currently it is known that industrially for each ton of iron ore concentrate produced one tailings ton is generated about 4118 million tonnes year 2
