In total, 810 h of operation with ilmenite ore have been reported from eight different pilots: ... In this process, impurities in TiCl 4, such as FeCl x, and AlCl 3 with boiling points that differ considerably from that of TiCl 4 (409 K) are condensed and removed (Fig. [12]). On the contrary, impurities with boiling points similar to that of TiCl 4, such as VOCl 3, SnCl 4, and SiCl 4 ...
Review of processing conditions for Murray Basin ilmenite ...
Canada. However, as impurities in the ilmenite report to the slag, the direct appliion of smelting to Murray Basin ilmenites may not be possible because of the References elevated levels of magnesium in the ilmenites. Ahmad, S., Rhamdhani, M. A., Pownceby, M. I. and Bruckard, W. J. Even so, it may be useful to evaluate the TiRON (2014 ...
Determination of impurities in ilmenite ore and residues ...
· The concentrations of these metal impurities in the ilmenite ore as determined by the EDXRF method in this study are summarized in the first row of Table 2. Since Nb is present both in the ore and the residue it is quite natural to expect the presence of Ta as well in these samples, but Ta is close to W in the periodic table, so their characteristic Xray lines (L lines) will be close together ...
Extraction behaviours of titanium and other impurities in ...
Experiments on the extraction behaviours of titanium as well as other associated impurities of ilmenite such as iron, silicon, calcium, and aluminium were carried out. The effects of various parameters, including reaction temperature, KOH concentration, reaction time, alkalitoore mass ratio, and particle size on the extraction rate of titanium and other impurities were examined. When the ...
