Sirovi bentonit se uglavnom dobija rudarenjem. Izvlači se u tvrdoj formi i najčeše ima prirodnu vlažnost oko 30%. Nakon što se izvadi bentonit se lomi i suši do vlažnosti od 15% i prosijava se u određenoj granulaciji ili se melje u prah. Prvo nalazište bentonita se nalazi u mjestu Fort Benton u državi Vajoming u SAD-u.
