summary of apgs technologies from ann. report

Hi y'all. I tried to summarise the APG technologies previously. The Annual report descriptions are excellent and you should read them. I've extracted the summary here as it's the best summary I've seen.

Award-winning Technologies
in the Titanium, Steel and
Iron Ore Industries

Austpac’s key technology transforms ilmenite
into high grade synthetic rutile, which is used
for titanium dioxide pigment manufacture
and is a preferred feedstock for titanium
metal production.

A second Austpac technology is used to process waste
chloride solutions and iron oxides produced by steel
making to recover hydrochloric acid and iron metal.
A third process can be used to upgrade the low value
hematite and magnetite iron ore fines created by iron
ore mining and produce valuable iron metal.
The four most important components of our
intellectual property are summarised below:

> ERMS SR (Enhanced Roasting and Magnetic
Separation Synrutile) process – a unique process
to upgrade ilmenite, a common titanium mineral.
The process comprises two steps. In the first step,
ilmenite is roasted to condition it for leaching. It
is then leached in hydrochloric acid to remove the
iron component. The TiO2-rich product is called
synrutile. The spent leach liquor is then treated
by Austpac’s EARS acid regeneration process to
produce fresh acid. The ERMS SR process thus
produces two valuable products; ultra high grade
synrutile and metallic iron pellets.

> EARS(Enhanced Acid Regeneration System)
process – a patented process to recycle waste iron
chloride solutions from the titanium and steel
industries and produce fresh hydrochloric acid
and iron metal pellets. By adding iron oxide
wastes from the steel industry, the yield of iron
can be significantly increased, so adding value to
steel waste treatment.

> DRI(Direct Reduced Iron) process – Austpac’s
new value adding process to make direct reduced
iron (DRI) from iron oxides generated by the
EARS process and iron ore fines in order to
produce a high grade feedstock for use in arc
furnaces for steel making.

> LTR(Low Temperature Roasting) process –
employs controlled low temperature fluid bed
roasting to enable ilmenite to be easily separated
from deleterious minerals so it can be used in the
sulfate process to make titanium dioxide pigment
