Technology
PRiSM is producing high-purity samples for market testing and conducting detailed engineering for full-scale production facilities. The goal: shorten the path from feedstock validation to commercial deployment while reducing the technical and financial risk of scaling up.
Designed for scale
Advanced HPA Production Process
Lava Blue produces High Purity Alumina at 4N and 5N grades from unconventional mineral sources. Our proprietary HCl leaching process works with kaolin clay, mine tailings, and waste. Validated from lab through to pilot scale at PRiSM.

Advanced high-purity alumina
From Feedstock to Finished Product
Feedstock
Kaolin clay, mine tailings, and industrial waste streams.
Digestion
Proprietary HCl leaching dissolves the aluminium content.
Recrystallization
Repeated recrystallisation drives off impurities.
Calcination
High-temperature calcination converts to alumina.
Milling
Milled and classified to the target particle size.
- HPA-Infused Pastes
- Coated Battery Separators
- HPA for Advanced Ceramics
- Sapphire Grade HPA

Innovation Pipeline
Lava Blue's technology platform is expanding in two directions: new materials and smarter processing. We're developing recovery pathways for critical metals like cobalt, bismuth, and rare earths from unconventional sources. At the same time, we're integrating machine learning into process modelling, quality control, and operational workflows.
