FYI Achieves Outstanding Grade Recovery of 99.999% (5n) Purity Alumina
(firmenpresse) - FYI Achieves Outstanding Grade Recovery of 99.999% (5n) Purity Alumina
- FYI has successfully produced 99.999% alumina (5N) during the Locked Cycle test work it is currently undertaking
- The 5N product was produced via FYIs standard process flowsheet and within standard operating conditions
- Achieving the 5N product demonstrates the quality of the process design and suggests that there is potential for positive improvements to the project capex, opex and overall economic case previously set out in the pre- feasibility study (PFS) released to the ASX on the 25th September 2018.
- The 5N market is moderate in size compared to the 4N market, however it is forecast to grow at a rapid rate (~ 22% CAGR)*
- To date no other ASX listed kaolin HPA company has demonstrated the ability to produce ultra-high purity 5N product
High Purity Alumina (HPA) developer, FYI Resources Limited (ASX: FYI) (the Company or FYI) is pleased to announce the production of 99.999% purity Al2O3 during continued product development and benchmark variability test work for the Companys flagship HPA Project bankable feasibility study (BFS). The purity of 99.999% alumina was independently analysed and verified by Ultra Trace Pty Ltd in Perth.
As a component of the BFS test work and Locked Cycle testing (please see FYI ASX announcement 6th March 2019), the Company has achieved the outstanding product grade of 99.999% alumina.
The test work is designed to provide data and information from the process flowsheet results of the laboratory-based test work as a replication of the full scale (production sized) process design.

FYI Resources 99.999% (5N) high purity alumina
FYIs Managing Director, Mr Roland Hill, commenting on the results said: Achieving 99.999% or 5N HPA is an extremely encouraging result. Not only is it an incredible outcome to attain this level of purity, it also has a potentially profound impact on the overall project economics.
Whilst focusing on the 4N as the predominant HPA market segment, FYI sought to produce 5N HPA to demonstrate the flowsheet effectiveness, as well as to develop an additional product line that could supply a market that displays forecasted long-term growth at a significant premium to the 4N market.
Demonstrating the strong premium to the 4N market, Allied Market Research estimates 4N HPA product to sell in a range from US$30,000 - $35,000/t in 2018/19 versus over US$50,000/t for 5N. We believe the ability to generate such a ultra-high purity product continues to demonstrate the Cadoux Kaolin Project is world-class potential and we look forward to progressing discussions with possible end use customers.
5N HPA Market Expected to Grow
4N HPA is a highvalue product that has many broad traditional applications and is increasingly becoming a critical component in the electric vehicle , battery and power storage markets.
5N is a sub-set of the HPA sector with smaller market applications that are generally tailor-made to the special requirements of each customer. However 5N attracts a significant premium in pricing over 4N due to its use in very complex applications. The greater portion of use for 5N being in the medical, aerospace and defence, and automotive sensors sectors.
5N HPA finds application in LEDs that are used in traffic lights, outdoor displays, and high-performance back light units. The growing demand for these products is one of the key driving factors for the 5N market. Leading players in this market are focusing on developing environmentally friendly 5N HPA using less energy. Such product innovations and technological advancements may provide an opportunity for FYI Resources in the world HPA market.

Allied Market Research (HPA Market Report 2016) has stated the Asia-Pacific 5N HPA market generated revenue of $430 million in 2015 and is estimated to generate a revenue of $1,554 million by 2022, registering a CAGR in sales of ~ 21.9% during the forecast period.
5N HPA Testwork: Further Detail
The 99.999% Al2O3 sample was generated by combining phase 1 precipitate solids from previous testing to determine the aluminium chloride hexahydrate crystal size.
The solids underwent another stage of precipitation testing with intermediate distilled water leaches to resolubilise the aluminium chloride hexahydrate. To target an increased grade, each precipitation stage targeted lower stage recoveries of ~90%, lower when compared to the +95% previously utilised for all other precipitation testing for 4N (99.99%) product material.
The assay for 99.999% HPA was conducted by Ultra Trace in Perth utilising the following method:
a. Lithium Borate Fusion at a 12:22 flux ratio;
b. XRF Analysis - Low Level detection;
c. Multi stage LOI by Thermal Gravimetric Analysis (300, 475 and 1,000°C);
d. Laser Ablation - Inductively Coupled Plasma - Mass Spectrometry.

drying and splitting of individual samples and
then compositing into representative samples.
The sampling procedures were under the control
of qualified and experienced IMO employees and
considered adequate for the intended

Master composite samples were prepared
representing the Cadoux resource with alumina
feed grades ranging from 21.5% to

The composites underwent a stage of
attritioning with the products screened to
generate fine and coarse size
fractions.
The fine attritioned product underwent one
stage of calcination to convert kaolin clay to

Geology The project area is underlain by weathered
granitoid Archaean rock of the
Yilgarn Granites is the likely parent material
for the kaolin. Here, deep weathering of the
feldspathic and ferromagnesian minerals within
the metamorphosed granitic has resulted in the
formation of kaolinite. There is no outcrop
but recognizable
granitoidal fragmental rocks are sometimes
present just below surface. The crust of the
overburden comprises gravel and sands over
reddish to off white clay. White kaolin
underlies the overburden followed by weathered,
partial oxidised and then fresh
ganitoids at depth. The recent drilling at the
property has revealed a weathering profile
which is very common in Western Australia with
the granitoid rocks, deeply weathered forming a
leached, kaolinized zone under a lateritic
crust. Analysis at the Laboratory shows
particle size distributions are typical of
primary style
kaolins produced from weathered granites. The
crust of overburden comprises gravel and sands
over reddish to off-white clay to an average
depth of 5m. White kaolin then averages
approximately 16 m before orange to yellow
sandy and mottled clays are intersected which
are followed by recognizable rounded granitoid
material. The thickness of the kaolin profile
varies from less than 1m to a maximum of 22m.
Fresh granitoids are found at depths of between
10 and 30m. All kaolin resources are within 4
to 11 metres of the surface. 75 Reverse
circulation
drillholes were completed with a total of 1,613m
drilled. All holes were drilled vertically.
Intersected kaolin thickness ranged from
4-28m.

reporting
Other Metallurgical test-work is being conducted on
substantive composite kaolin samples by IMO. IMO are
exploration following a standard diagnostic flowsheet
data template to determine aluminium leaching and
precipitation characteristics of the
kaolin.
The test work involves the following procedure
of
composited
kaolin samples of the recent drilling program
(see FYI ASX announcement dated
9
th June 2018)
The sample was calcined at for one hour to
convert the Kaolin to an acid soluble
species.
The sample was then leached in 26% (w/w)
Hydrochloric acid at 20% solids and 100°C for
180 minutes with samples being collected to
provide kinetic leach
recoveries.
As a component of the Locked Cycle test work
(see FYI ASX announcement
6
th March 2019), IMO targeted high grade Al2O3 pro
duction.
Leach testing was conducted in a glass leach
vessel containing concentrated feed sample
scalped at 106 µm and concentrated industrial
grade hydrochloric
acid.
The 99.999% Al2O3 sample was generated by
combining phase 1 precipitate solids from
previous testing to determine the aluminium
chloride hexahydrate crystal size which had
been in storage for ~1
month.
The solids underwent additional stages of
precipitation testing with intermediate
Distilled Water leaches to resolubilise the
aluminium chloride
hexahydrate. To target an increased grade, each
precipitation stage targeted lower stage
recoveries of ~90%, lower when compared to the
+95% previously utilised for all other
precipitation
testing
.
The assay for 99.999% HPA was conducted by
Ultra-trace in Perth utilising the following
method:
a. Lithium Borate Fusion at a 12:22 flux ratio;
