In January 2005 Alcoa of Australia
Pty Limited, trading as Alcoa
World Alumina Australia (Alcoa),
and the Three Party JV entered
into a contract that permitted
up to 2,000 tonnes of Salt Slag
and aluminium dross from
Alcoa?s Moolap landfill site to
be processed to determine the
feasibility of a full-scale recovery
and remediation of all Salt
Slag and associated material at
Moolap. This contract included
the intention, should the initial
trial be successful and subject to
Alcoa, Environmental Protection
Authority (EPA) and Council
approval, for the parties to
negotiate an agreement for the
recovery and remediation of all
Point Henry Salt Slag landfill areas
on the same principles.
In April 2006 the results of the
initial trial were presented to
Alcoa and Alcoa agreed the
viability of the ALNAK technology.

Another Tid Bit from that report

EBIT of $85 Tonne processed for the six months ended 30th June 2010 Just on the processing alone.

It viable to Alcoa because they get to keep Aluminium and Salt

Sign up for 1M tonnes and that is $85M profit alone before any thing else. We currently are 1/4 of the way there With SSC and Moolap
