No, it consumes olivine dust; it doesn't produce it. Olivine dust is full of potentially toxic metals, but as long as you aren't inhaling it, you don't have to worry about them. Olivine isn't water-soluble.

- kragen 1y agoAren't the metals the CO₂-absorbing part? Olivine is the fayalite–forsterite–tephroite continuum. Fayalite is Fe₂SiO₄. Forsterite is Mg₂SiO₄. Tephroite is Mn₂SiO₄. (Admittedly, as metals go, those aren't very toxic.) If you remove the metals from olivine what's left over is silica. Like, quartz. It doesn't absorb CO₂.
