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 into titanium dioxide slags, iron, 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
QIT Red Dust may be substituted for by
standard Red Iron Oxide

QIT Poussière Rouge
QIT
–Fer et Titane du Québec possède une énorme mine d'ilménite dans le
nord-est
québecois.
Le minerai est transporté par navire sur le fleuve St-Laurent jusqu’à Tracy
où
il est transformé en scories bioxyde de titane, fonte, billettes en acier et
pièces automobiles entre autres. Cette poussière provient du système
anti-pollution de son acierie, et a la formule générale suivante:
FE2O3 85%
SIO2 5.0%
CAO 5.0%
MGO 1.0%
ZNO 2.0%
CARBONE 2.0%

Ce
déchet a été tamisé à 170 mailles.
La
substitution théorique suivante peut s’appliquer pour chaque 1% de cette
matière :
