The Effect of Titanium on Reduction Degradation of Iron Ore
The Effect of Titanium on Reduction Degradation of Iron Ore Agglomerates. A strong correlation between the reduction degradation index (RDI) of production sinter and the titanium content of the sinter mix was identified at the Ruukki sintering plant between 2000 and 2004. The titanium distribution in different mineral phases was studied using ...

Titanium, Chemical Element
Pure titanium metal can exist as a dark gray, shiny metal or as a dark gray powder. It has a melting point of 1,677°C (3,051°F) and a boiling point of 3,277°C (5,931°F). Its density is 4.6 grams per cubic centimeter. Titanium metal is brittle when cold and can break apart easily at room temperature.

New perspectives in iron ore flotation: Use of collector reagents
In conventional operations of iron ore beneficiation by flotation, the flotation feed is deslimed to remove the 10 µm fraction prior to flotation (Filippov et al 2014), thus the unselective flocculation effect of starch does not affect the flotation selectivity. Contrary to what occurred in this study, where the pure mineral samples used for ...
