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

Slater Dust

Slater Steels is a maker of special alloyed steels.

This dust is an industrial waste material.
It comes from the anti-pollution system of the furnace.

Slater Dust has the following general analysis :
SiO2 5.39%
Fe2O3 50.3
CaO 12.12
MgO 3,27
ZnO 34.28
Total 100
Also small amounts of nickel, chromium, molybdenum,
cadmium, and manganese.

A possible substitution for 1% of this stuffis as follows :
