Complete detailed engineering and procurement of plant facilities and

up 500,000 t/y line.
Estimated costs 120 million USD.
In a third phase when the sylvinite project is underway, in parallel to development of
the second 500,000 t/y line to complete the full 1 million tonne
per year capacity, the
following recommendations are made to potentially; (i) reduce the already relatively
low OPEX and eventually the sustaining CAPEX and, (ii) increase the lifetime of the
project.
o
To increase the lifetime of the operation or the annua
l production it is
recommended to investigate the extraction of Carnallite for production
of MOP and/or SOP products. Solution mining the Carnallite in the d
e-
posit could also greatly reduce sustaining CAPEX requirements by
vastly increasing the life of a c
avern, thereby reducing the amount of
new
caverns, which
must be drilled annually.
o
In this study HFO generators have been selected to provide the full
energy require
-
ments for the operation. This has resulted in a large
proportion of the OPEX being dedica
ted to fuel for power generation.
This decision may not be optimal, and studies should be initiated to
evaluate the economic potential of using alternative energy sources to
reduce OPEX. For example:
•
Connection to the national grid ~120 km from project si
te.
•
Use of wind energy; with favorable wind conditions at ground level over most
of the day.
•
Use of the ubiquitous solar energy available in Dallol, eventually combined
with HFO/Diesel generators.
•
Use of geothermal
energy, which
has a large potential due
to the high g
