QIT Red Dust
QIT stands for Quebec Iron
and Titanium. QIT owns an ilmenite mine in northeastern Quebec.
The ore is shipped to Tracy where it is processed to titanium dioxide slag,
iron pigs, steel billets
and steel autoparts. This dust comes from the dust collecting system of the
steelmelting department
and has the following general formula:
FE2O3………………. 85%
SIO2 ………………….5.0%
CAO ………………….5.0%
MGO …………………1.0%
ZNO ………………….2.0%
CARBON ……………2.0%
TOTAL ……………100%
It was 170 mesh sieved.
A theoritical substitution is as follows for each 1% of the stuff :
Red Iron Oxide ………..0.820
Silica …………………..0.050
Whiting ………………..0.060
Dolomite………………0.050
Zinc oxide …………….0.020
Total…………………..1.000
Common Iron Oxides could be Good Substitutes
