Bentonite

Product Details:

Overview
Oreworld Trade (Tangshan) Co., Ltd. has extensive reserves of high quality Sodium and Calcium Bentonite which are mined & processed carefully into several grades. These are in different forms such as dried & crushed lumps, granules, powder to micronized powder, catering to diverse needs of clients.

Our Bentonite products cater to a wide range of industries starting from the conventional usage areas of Iron Ore Pelletisation, Drilling, Metal Casting, Ceramic, Construction, Pet Litter etc. to value added areas such as paper, detergents etc.

Bentonite is a highly colloidal clay mineral. The multiple properties of bentonite namely hydration, swelling, water absorption, viscosity, thixotropy make it a multi-application product for diverse industries. Primarily two varieties of bentonite are available - sodium bentonite (high swelling, gelling and thermal durability) and calcium bentonite (more commonly available worldwide but with less swelling).

PROPERTIES AND USES:
Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets, and in foundry and oil - well drilling mud. Bentonite also acts as a suspending agent in oil - well drilling fluids. Bentonite exhibits good green strength along with high hot and dry strength which helps in preventing moulds from breaking or cracking during the pouring or cooling processs in the foundry industry. Owing to high green strength resulting from its property to absorb and then release moisture, bentonite is used in iron ore pelletisation. Sodium-based bentonite of 75 mm size finds suitability in iron ore pelletisation for bonding by user industries. Bentonite has also remarkable colloidal and waterproofing properties. Bentonite gels are used as a carrier for a number of cosmetic preparations, toothpastes, creams, etc. Bentonite is also used in chemical, rubber, insecticide & pesticide industries and in civil construction works. Bentonite in the form of fine powder free from dirt and other foreign matter and of least swelling property is used in ceramic industry.

Bentonite for Ceramic

Bentonite is used as a binder in high temperature furnace cements, mortars, and furnace gun mixtures. Both are used as a suspension agent in glazes and porcelain enamels and a plasticizer in white wares for electrical porcelain bodies, floor tile, wall tile, and sanitary ware for increased green strength, fired strength, and to reduce absorption.

Bentonite for drilling

Sodium based bentonite is as a mud constituent for oil- and water- well drilling. Its role is mainly to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head. The special higher mud yield results in using less quantity of Bentonite for the same standard mud. This results in lesser requirement of Bentonite.

We can produce based drilling bentonite well meeting European standards of OCMA grade and the United States standards of API grade.

Bentonite for Iron ore Pelletisation

Applications of bentonite for iron ore pelletisation

1)Aids in pellet binding of iron ore

2)Improves heat transfer in steel production resulting in lower energy consumption per ton of steel produced

3)Good desulfurization, return ore quantity is little
