Bentonite - Minerals Raw Materials - aka-mining

Pelletizing: Bentonite is used as a binding agent in the production of iron ore pellets. Through this process, iron ore fines are converted into spherical pellets, suitable as feed material in blast furnaces for pig iron production, or in the production of direct reduction iron (DRI). Construction and Civil Engineering: Bentonite in civil ...

Bentonite - Wikipedia

The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. As of around 1990, almost half of the US production of bentonite was used as drilling mud. Minor uses include as a filler, sealant, and catalyst in petroleum refining. Calcium bentonite is sometimes marketed as fuller's earth, whose uses overlap with those of other forms of bentonite. Bentonite is used in drilling mudto lubricate and cool the cutting tools, to remove cuttings, and to help pr
