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 also 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.
