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 billetsand steel autoparts.
This dust comes from the dust collecting system of
the steelmelting departmentand 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

It may be replaced by 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
