We are a leading North American producer and exporter of premium iron ore pellets and high grade concentrate with average iron grades greater than 66 . Our operations include a mine with five operational pits, a concentrator and a pelletizing plant located near Labrador City, in the province of Newfoundland and Labrador.
The offered grades for the sale of iron ore concentrate in the global index are often three concentrations of iron 67 , iron concentrate 66 , iron concentrate 65 . Although grades above 67 range from 67 to 69 , they are also in demand. Sales iron ore concentrate 67 Fe and higher grade
The recleaner column feed grade ranges between 1 and 6 silica, therefore, one column stage is sufficient to produce either blast furnace or direct reduction concentrate. A scavenger column has been added to the flowsheet to maximize fine iron recovery particularly during the periods where direct reducing grade is being produced.
In addition, it is revealed that low grade iron ore with a high pore properties, α FeOOH content, and gangue content can be upgraded to a high grade iron ore with a low pore property low specific surface area and pore volume, high Fe 2 O 3 content, and low gangue content using the above method.

This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 mTPY of dr grade concentrates. This paper describes the benefits of column flotation and discusses some important aspects of circuit design.
Low grade ore is a term applied to iron rich rocks with cut off grades in the range of 25ï¿䧲 Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low grade ore. The dominant economic iron mineral in low grade ore isite.
A recent trend has been production of a high gradeite concentrate from beneficiation of low gradeite ore. Resources of this latter material are enormous, in particular in Western Australia, and South Australia, with significant resources also in the Northern Territory, and Queensland. The history of iron ore prices differs significantly from other metals. For most of

Metallic iron is virtually unknown on the surface of the Earth except as iron nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth most abundant element i
