Bentonite
Dogu Stone has contracted Bentonite quarries at Giresun and Ordu.
The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. Minor uses include filler, sealant, and catalyst in petroleum refining. Bentonite is also used as cat litter.
Chromium
Dogu Stone has contracted Chromium mines and quarries at Adana, Denizli, Erzincan, Erzurum and Mersin.
Chromium (or Chrome, Cr) metal is valued for its high corrosion resistance and hardness. The creation of metal alloys account for 85% of the available chromium’s usage.
Chromium is also used in the chemical, refractory, and foundry industries. It is used to harden steel, to manufacture stainless steel (named as it won’t rust) and to produce several alloys. Chromium plating can be used to give a polished mirror finish to steel.
