Slide 2: Project Overview and Strategic Partnership
Project Overview and Strategic Partnership Three complementary partners aligning resources, research, and technology around petalite conversion. Andrada Mining GTK Metso EU funding application Uis lithium resource, Sodium/alkaline leach coordination, applied Operating Mine, and expertise and industr
Slide 3: Grade and Recovery Evaluation
Grade and Recovery Evaluation Value is optimised across the whole flowsheet - not by concentrate grade alone. Ceramic-grade target Shift from ProLith conversion target grade only target 4.2% Li₂O 3.5% Li₂O to whole-system considerations value Higher concentrate specification Optimise recovery + Fewe
Slide 4: The Traditional Metallurgical Challenge
The Traditional Metallurgical Challenge Validation focus: assessing whether Uis petalite can be processed directly without a calcination stage. Energy- Intensive Spodumene route Thermal Activation Potential enabler Removing petalite calcination will lower process intensity and operating burden — tes
