Fly ash-grade aluminosilicates surface in lithium processing

Toronto-based Rock Tech Lithium Inc. cites the potential to extract a supplementary cementitious material from leached spodumene concentrate (LSC), a byproduct of its lithium hydroxide processing whose typical chemical composition is primarily aluminosilicates (65 percent SiO2, 25 percent Al2O3). With an eye to electric battery markets, Rock Tech plans to commercialize the lithium hydroxide process through construction of converter facilities…
