Phosphorus Iron. The combination of high purity iron and 0.45% Phosphorus creates a powder that is highly compressible and allows extremely high density (up to 99% of theoretical density) to be achieved during the SGT sintering process. This creates a mechanically tough finished component with excellent magnetic properties (very high saturation).

Froth Flotation of Iron Ores - sapub

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.

The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 3-7% silica and less than 3% aluminium. The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be reduced to enable efficient magnetic separation to provide a high purity magnetite concentrate.
