Yet, bentonite does not undergo any such chemical reactions within pellets. Instead, bentonite physically binds to iron ore particles. Bentonite additionally controls excess water within the pellet. Sodium bentonite in particular can absorb around 900% PWA, allowing pelletization moistures to remain considerably more consistent than …
A new process for manufacturing organically compounded bentonite was developed successfully based on the organic intercalation and layered structure of bentonite. The main steps in the proposed process included wet sodium activation of bentonite ore, organic compounding and high-pressure roll grinding. The optimum …
