PERTH, Australia, Sept. 23, 2011 /CNW/ - Elemental Minerals Ltd. (ASX, TSX: ELM) ("Elemental" or the "Company")
is pleased to announce positive results from the metallurgical test
The metallurgical test work program has been completed and returned
Low impurity content was confirmed, minimising environmental impact and
offering the potential for a simple insoluble removal stage, which
should result in better than average reagent utilization.
Relatively coarse liberation will not require fine crushing / grinding
which could lead to good brine recovery, less fines losses and better
Good flotation recoveries indicated by the test work programme suggest a
simple rougher / cleaner / regrind flotation configuration
METALLURGICAL TEST WORK PROGRAM
The metallurgical test work program was completed by the Saskatchewan
Research Council, industry recognized leaders in potash process
testing, under supervision of AMEC Americas. The test work was
conducted on a 100kg representative sylvinite sample. The results are
very encouraging and it is management's belief that these results will
translate into significant capital and operational cost advantages
during the current phase of design.
Mineralogical analysis showed that the composite sample was composed of
38% sylvite (24.2% K2O) confirming the high grade nature of the deposit, with an insoluble
content (identified as mostly anhydrite) of less than 1%.The sample can
be categorised as coarsely intergrown sylvinite.
The main conclusions from this initial work are:
An effective and simple conventional process flow sheet has been
indicated as required to achieve high recoveries and grades.
The high grade quality of the Sintakoula feed material with low
insoluble content may only require a simple desliming stage with
Fast flotation kinetics suggests a simple and cost effective flow-sheet.
Initial bench scale rougher / regrind / scavenger flotation achieved
recoveries up to 96.5%with the scavenger flotation tails containing
less than 1.5% KCl. One stage of cleaner flotation upgraded the rougher
concentrate to 95.9% KCl grade.
Locked cycle testing produced above average results with high recoveries
(93.0% to 94.8%) and high concentrate grades (93.9% to 95.9%).
Flotation concentrate grades produced are very close to final product
grade suggesting that little or no concentrate leaching may be
Optimisation of the flow sheet is underway.
Remarking on the metallurgical testwork results, Elemental's CEO, Iain
Macpherson, commented: "We are highly encouraged with the outcome of this preliminary process
development work that highlights the benefit of our high grade, clean
Sintoukola sylvinite resource. The benefits range from a suggested
simple and cost effective process flow sheet with low reagent
consumptions to a high quality end product. More work will naturally be
undertaken as we progress with our pre-feasibility study, but
this preliminary work is a key milestone and suggests significant
upside on the processing capital and operating costs used in the
Company's previously released Technical Report."
