The AMRT Technology and Process
The AMRT Mineral Recovery Process utilizes a patented
electric arc furnace/smelter technology uniquely suited
to profitably solve environmental and sustainability
problems in the metals industries in the new century.
The Process
◦ Efficiently extracts valuable metals from a wide variety of
feedstocks
◦ Addresses significant toxic waste problems, turning liabilities into
profit-making assets
◦ Has low breakeven points (furnace size & commodity price)
◦ Can directly process “fines” and other problematic materials
without intermediate steps
◦ Ideally suited for local empowerment
◦ Energy efficient

Bauxite
Residue
 Bauxite residue – or ‘Red Mud’ – is produced during the
production of alumina from Bauxite using the Bayer Process
invented in 1888
 Bauxite residue is a high-volume hazardous waste which is typically
stockpiled or dumped with little or no treatment
 3 billion tons have been dumped or stockpiled worldwide
 Approximately 120 million tons/yr being produced without an
economical or environmentally sustainable solution.

AMRT and the European Commission co-funded two
furnaces in Greece through 8.5 M euro ENEXAL Program to
demonstrate treatment of bauxite residue (Red Mud):
◦ A 400 kVA furnace installed and operated with the National Technical
University of Greece (NTUA) at Ypato, 60 miles north of Athens
(commissioned 2011 – decommissioned 2014 at conclusion of project)
◦ A 1 MVA furnace installed at the plant site of Aluminium of Greece
about 60 miles west of the NTUA site (commissioned 2012)
AMRT furnace technology selected on sole source basis as no
other technology had the capabilities to use dust directly,
finely control the smelting process and extract all the iron.
The Program has demonstrated that pig iron and mineral
wool for industrial insulation can be produced from Red
Mud using the Process furnace technology and commercial
fiberization equipment.

“First – Get the Red Out”
◦ AMRT Technology is the only one demonstrated to do so
efficiently and produce marketable product
◦ Covers 40-80% of processing costs depending on power and
other costs.
Then use the clean, low cost molten slag
◦ Commercial spinning of high quality mineral wool for industrial
insulation demonstrated; commercial & residential insulation
possible for many bauxite sources.
◦ Should demonstrate ability to produce low cost glass fiber for
wind turbine blades, similar applications
◦ Other marketable products such as cement additives and rare
earth extraction have much lower economic hurdles “after the
red is out.”
