He kohuke kore-whakarewa te Bentonite, ko te montmorillonite te wāhanga matua o te kohuke. Ko te hanganga o te montmorillonite he hanganga tioata momo 2:1 e titoa ana e ngā tetrahedron hāora silicon e rua e piri ana ki te paparanga o te octahedron waikura konumohe. Nā te mea he maha ngā kationa o te hanganga paparanga i hangaia e te pūtau montmorillonite, pērā i te Cu, Mg, Na, K, me ētahi atu, ā, he tino koretake te mahi a ēnei kationa ki te pūtau montmorillonite, he ngāwari ki te whakawhiti e ētahi atu kationa, he pai te kaha whakawhiti katote. I tāwāhi, kua whakamahia i roto i te neke atu i te 100 tari i roto i te 24 mara o te whakaputa ahumahi me te ahuwhenua, me te neke atu i te 300 hua, nō reira ka kiia e te tangata ko te "oneone whānui".

E mōhiotia ana hoki te Bentonite ko te bentonite, te bentonite, te bentonite rānei. He roa te hītori o Haina ki te whakawhanake me te whakamahi i te bentonite, i whakamahia tuatahitia hei hopi horoi anake. I ngā rau tau ki muri i reira ngā maina tuwhera i te rohe o Renshou o Sichuan, ā, i tapaina e ngā tāngata whenua te bentonite ko te paura uku. He whānuitia te whakamahinga engari he neke atu i te kotahi rau tau te hītori. Ko te kitenga tuatahi i te United States i roto i ngā papa whenua tawhito o Wyoming. Ka taea e te uku chartreuse te horapa hei whakapiri i muri i te tāpiri wai. Nō muri mai, ka tapaina e te tangata ngā uku katoa me tēnei āhuatanga bentonite. Inaa, ko te hanganga kohuke matua o te bentonite ko te montmorillonite, me te ihirangi 85-90%. Ko ētahi āhuatanga o te bentonite ka whakatauhia hoki e te montmorillonite. Ka taea e te Montmorillonite te whai i ngā tae rerekē, pērā i te kōwhai kakariki, te kōwhai mā, te hina, te mā, me ētahi atu. Ka taea e ia te hanga poraka matotoru, te oneone wetewete rānei, me te ahua pahekeheke ina mirimirihia ki ngā maihao. I muri i te tāpiri wai, ka whakawhanuitia te rōrahi o ngā poraka iti kia maha ngā wā ki te 20-30 ngā wā, ka puta hei āhua iri i roto i te wai, ā, hei āhua whakapiri ina iti te wai. Ko te āhua o te montmorillonite e pā ana ki tōna hanganga matū me tōna hanganga o roto.
