CLAYSTONE PROCESSING

CLAYSTONE PROCESSING

• Process is comprised of 3 functional areas: Ore Preparation & Leaching,

Sulfuric Acid Plant, & Lithium Processing Plant

• No new process technology, only traditional chemical processing equipment

used in unique ways, specific to the LNC extraction process:
