Bentonite deposits are most often quite large, with lenticular beds, only a few meters deep. Bentonite production process features ore mining, sodium activation – if required -, drying, and milling. Sodium activation is performed to convert calcium bentonite to sodium bentonite, in which calcium ions are exchanged for sodium carbonate.
