High Purity Alumina or HPA is a specialty product of at least 99.99% pure Al2O3. It is a bad conductor of electricity and has a very high melting point. HPA finds its application in LED lighting, semiconductors, lithium-ion battery separators, scratchproof artificial sapphire glass, fingerprint readers and many more. Demand for high purity alumina stood at nearly 25,315tpa in 2016. During the period of 2016-2024, global HPA market is forecast to exhibit a CAGR of 16.7%, on account of rapid adoption of HPA in these applications.
High purity alumina (HPA) is emerging as the major material used in lithium-ion batteries, backed to its features. HPA is expected to the next major battery metal. Some of HPA benefits in lithium-ion batteries are as follows:
- HPA is a bad conductor of heat. Since lithium-ion batteries generate a lot of heat, they can catch fire. However, HPA use makes them safe.
- Separators coated with HPA boosts the thermal stability and efficiency of the batteries. According to some sources, high purity alumina of 38,000tpa would be needed for coating the separators in lithium-ion batteries by 2025.
- HPA also enhances battery life cycle and reduces self-discharge.
Several companies are getting engaged in the business of HPA, banking on growing demand for the material in the coming years. Some of the major stocks listed on ASX that are dealing in the HPA market are:
- Altech Chemicals Ltd (ASX: ATC)
- Pure Alumina Limited (ASX: PUA)
- FYI Resources Limited (ASX: FYI)
- Platina Resources Limited (ASX: PGM)
- Nova Minerals Limited (ASX: NVA)
Let us have a look at recent updates from three of these ASX-listed stocks and see how their stocks are performing.
Pure Alumina Limited (ASX: PUA)
Sydney-based Pure Alumina Limited is a producer of HPA and gold in Australia. Based on its partnerships and product quality, the company intends to become a premier supplier of high purity alumina. The company is working on Yendon HPA and Hill End Gold projects. After completing the acquisition of Polar Sapphire, a Canada-based high purity alumina producer of high-quality 5N HPA, PUA plans to use Polar's patented technology to build a commercial-scale factory for high purity alumina.
On 17 June 2019, Pure Alumina Limited released its revised investor presentation with changes suggested by the Australian Securities Exchange in its Investor Presentation made on 14 June 2019.

PUA is currently in the process of raising capital to fund the acquisition of Polar Sapphire and development of its planned facility. Polar can use lower cost feedstock to produce 3N and 4N HPA and its innovative process produces the highest commercial grade of HPA, 99.999% (5N) HPA (Al2O3). The higher-grade boules produced by Polar have lesser defects, while the market produces boules with color, clarity and bubble defects. The pilot plant of Polar in Toronto, Canada, has an annual production capacity of 145 tonnes of high purity alumina. HPA demand registered an eight-fold growth since 2003 and is projected to triple by 2030.

Retaining wall construction work is almost 75% complete, while work on internal site retaining wall is advancing as per the schedule. Additionally, work on excavation of the on-site detention storm water tanks has started along the plant siteâs southern boundary. Construction work is being carried out on the first of four underground tanks. The tanks will serve as intermediate storage for all site storm water in line with the planning regulations and stormwater management practices adopted in Malaysia. The four tanks will have a total volume of 2,000 cubic metres.
In another statement on 14 June 2019, ATC announced the issue of 18,433,180 fully paid ordinary shares at a price of $0.1085 each share to SMS Investments SA. The development, which will result in a total consideration of $2.0 million, secured shareholder approval on 6 June 2019.

The company has mobilised drill crew and rig on the first spotted hole location and is set to start drilling program in the next few days. After the completion of IP and Magnetic geophysical surveys, the company will start surface sampling and geologic mapping program at RPM and Shoeshine prospects in early July 2019.
Pacific Rim Geological Consulting of Fairbanks Alaska carried out the 2018 mapping campaign at the project of Estelle Oxide. The campaign demonstrated that higher gold values are related to bismuth telluride and arsenopyrite mineral phases. The campaign also highlighted that sheeted quartz veins containing narrow alteration selvages hosts the mineralogy.
The project area of Estelle covers several alterations zones and structures, in addition to identified mineral occurrences within a huge tenure. The IP survey will focus the drilling down to the key areas that would result in tonnes for the companyâs maiden Inferred Resource, said NVA Managing Director, Avi Kimelman.
