QIT Red Dust--Poussière Rouge de QIT

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 –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%
TOTAL 100%

Ce déchet a été tamisé à 170 mailles.


La substitution théorique suivante peut
s’appliquer pour chaque 1% de cette matière :

Oxyde de Fer Rouge 0.820
Silice 0.050
Carbonate de Calcium 0.060
Dolomie 0.050
Oxyde de Zinc 0.020
