Outstanding FYI and Alcoa joint HPA trial production results continue to demonstrate process efficiency and product quality
Average HPA purity achieved for pilot plant trial Week Two samples is 99.9978% Al2O3
Progressive refinement of FYI's innovative HPA flowsheet continues
The robust test results support the HPA project development objectives between FYI and Alcoa
FYI Resources Ltd. ("FYI" or "the Company") (ASX:FYI; OTCQX:FYIRF; FSE:SDL), is pleased to announce the results of the second week of extended HPA pilot plant operations. An average purity of 99.9978% was achieved during the week-long campaign undertaken in collaboration with Alcoa of Australia (Alcoa).
Operating from the 7th to the 14th December 2021, the joint development HPA pilot plant trial generated product from which selected samples across all stages of the process were sent to EAG Laboratories in New York, USA for analysis using high level Glow Discharge Mass Spectrometry (GDMS) to provide independent, high accuracy confirmation of the HPA grades.
Consistent with the previous HPA trial outcomes, the Week Two results demonstrated continued high-quality grades being achieved across the suite of samples and ranged in purity from 99.9983% to 99.9973% Al2O3. The high-quality results further support the progressive development of FYI's project utilizing the effective and innovative HPA flowsheet design.
| | | Sample 1 | Sample 2 | Sample 3 | Sample 4 |
| HPA (Al2O3) Grade | % | 99.9983% | 99.9973% | 99.9980% | 99.9977% |
| Total Impurities | ppm | 17.1 | 27.4 | 20.3 | 23.1 |
Results from week Two of the extended pilot plant trail conducted from 7th to 14th December 2021 in joint development with Alcoa.
The pilot plant program supports the joint HPA development project between FYI and Alcoa for the commercialisation of FYI's innovative process for refining high quality HPA. The piloting program continues the optimizing of the process flowsheet. Whilst feedstocks variations and blends continue to be assessed, this trial run feedstock was supplied by Alcoa.
FYI Managing Director, Roland Hill, commenting on the results said "In the context of FYI and Alcoa's joint HPA development objectives, the latest results are very pleasing as we trial different variations of operating conditions. It is a joint objective for the continual improvement and optimizing of the HPA flowsheet by incorporating learnings from previous pilot plant trials and integrating them into the process design. The latest test results demonstrate the progressive advances in the process flowsheet that the joint development is achieving as well as incremental improvement in the overall project value".
Next Pilot Plant Trial
In progressing the joint HPA development program, the third extended pilot plant trial is scheduled to commence operation on 17th January 2022. This trial will be a continuation of the previous trial objectives, focusing on flowsheet refinement as well on HPA product generation for customer assessment purposes.
