Purebase Corp. anticipates a Q3 start-up for a calciner engineered to process reactive, concrete-grade metakaolin from an Ione, Calif. kaolin clay deposit. An ASTM C618-designated natural pozzolan, metakaolin presents a lower carbon alternative to portland cement, owing to the lower calcination phase heat, < 700°C versus 1,400°C+, required to drive off CO2 from calcium and other minerals. It can be used at portland cement substitution rates hovering 25 percent in concrete mixes.
