The purity of 99.999% alumina was independently analysed and verified by Ultra Trace Pty Ltd in Perth.
FYI Resources has achieved the outstanding product grade as part of its bankable feasibility study (BFS) test work and locked cycle testing for the Cadoux Kaolin Project.
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 managing director Roland Hill 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 poised for growth
4N HPA is a high‐value 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 subset 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.
Global market share by HPA purity
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 backlight units.
The growing demand for these products is one of the key driving factors for the 5N market.
