Titaco to toll-treat slag dump for Transalloys
Titaco Projects (Pty) Ltd, a BATEMAN subsidiary, together with its
associates Mintek and First National Bank (FNB), has been contracted
by Transalloys Pty Ltd to recover the ferro-alloys contained in a 7M
tonne slag dump located near Witbank in Mpumulanga, RSA. This is the
first ‘own-and-operate’ arrangement entered into by Titaco.
In terms of this toll-treatment contract, Titaco and its associates
will provide the process technology, build a recovery plant on the site,
operate it until the dump is exhausted and be paid by Transalloys for
the amount of ferro-alloy slag treated.
Titaco has considerable experience with the technology for recovering
ferro-alloys from slag, having to date supplied seven similar plants
to clients in Southern Africa. The design of the plant is based on test-work
carried out by Mintek. Titaco will design, procure, construct and commission
the plant under the turnkey construction portion of the contract. The
finances for the project have been provided by FNB.
The slag dump contains between 3 % and 4 % ferro-manganese and silicon-manganese,
of which about 95 % will be recovered. In the process the slag will
be converted into an inert coarse tailings material. In addition to
this environmental advantage, the non-metallic discards will be deposited
in the space vacated by the treated slag, obviating the need for a new
dump.
The plant will have a nominal 150 t/h capacity and be designed to
operate 24 h/day with an availability of 80 %. It will comprise a crushing,
screening and jigging process. The latter will be done using coarse
and fine APIC jigs with underbed air pulsation to provide sufficient
energy to pulse the large dense metal particles to separate them from
the slag particles. The APIC jigs will be supplied by Bateman Materials
Handling Limited under Titaco’s exclusive licence agreement with
the Fives-Lille Group, France.
