Austpac Resources N.L. has developed new
mineral processing technologies which add substantial value to ilmenite
by upgrading this low value titanium mineral into a high value product,
synthetic rutile, which is a prime feedstock used in the chloride process
to manufacture of titanium dioxide pigment.
Titanium dioxide (TiO2)
pigment is the brilliant white pigment used in the paints and plastics
industries and to a lesser extent in the paper industry and other uses.
TiO2
pigments are superior to all other alternatives and are sought after by
paint and plastics manufacturers throughout the world. The global TiO2
pigment market, which has grown over the last 20 years by 3% per year,
has a value of around US$8 billion per annum. Over 60% of the world's
TiO2
pigment is made by the chloride process. This process requires a feedstock
with a high TiO2
content (generally >85% TiO2).
Most natural sources of high TiO2
minerals, such as rutile, are exhausted, so chlorinatable feedstock is
manufactured from ilmenite, a common mineral generally containing around
50% TiO2.
Upgrading can be achieved either by electro smelting, which produces titania
slag, or by chemical processing to produce the >90% TiO2
material called synthetic rutile.
Austpac has been processing ilmenite for
over fifteen years and has developed a number of proprietary technologies,
including the ERMS and EARS processes.
The ERMS SR Process, which combines aspects of ERMS and EARS, cost competitively
produces the world's highest quality synthetic rutile (>96% TiO2).
Austpac's technologies are environmentally friendly and the end products
are free of the radioactivity issues associated with some alternative
technologies. The successful treatment of ilmenite samples from over 70
deposits indicates that the ERMS SR Process is the only one able to process
ilmenite found in any deposit around the world. Austpac has also developed
the LTR Process for low temperature roasting of both fresh and weathered
ilmenites. The LTR Process yields a product suitable for both the chloride
and sulfate route processes of pigment production. Ilmenite recovery is
high, generally greater than 90%. Austpac has applied for a patent for
a new reactor designed for the continuous leaching of ilmenite. This is
the CLR Process, which produces high grade synthetic rutile more efficiently
than the batch processes currently used in the feedstock industry. Austpac's
technologies are potentially the most significant and efficient technologies
available to the world market. Austpac's competitive advantage is its
ability to produce a superior product at a lower cost. The technologies
are protected by patents around the world.
