Yava has developed a proprietary process that has the following characteristics:
- Low capital costs—relies on readily available, reliable standard industrial equipment rather than custom designed processing equipment
- Regeneration of reagents yields a closed loop with minimal discharges—and no toxic waste
- Flexibility to use a variety of low cost, widely available feedstocks
- Very small carbon footprint (Yava Alumina’s demonstration plant in Quebec will consume low cost hydro-generated electricity)
- Capability to produce very pure HPA (99.998%) with target of 5N+
- Ability to produce HPA with physical characteristics (e.g., particle size and distribution, density, porosity) to meet the exacting specifications of end-users
Purity | Price Range (US$/kg) | Notes |
4N | $25 – $40 | varies based on metal impurities and other specs |
5N | $40 – $70 | ~2X the 4N value |
6N | >$60 | low volume, non-commodity sales |
