Bentonite

Introduction to Bentonite

  1. A rock composed essentially of a crystalline clay-like mineral formed by devitrification and the accompanying chemical alteration of a glassy igneous material, usually a tuff or volcanic ash.
  2. Smectite refers to a family of non-metallic clays primarily composed of hydrated sodium calcium aluminum silicate. Common names for smectite include montmorillonite or sodium montmorillonite (“sodium bentonite” or “Wyoming bentonite”) and swelling bentonite (“Western bentonite”).
  3. There are two types of bentonite:
    • Natural Calcium Bentonite or Calcium Montmorillonite
    • Natural Sodium Bentonite or Sodium Montmorillonite
  4. Bentonite minerals occur as lenses or seams containing up to 50% moisture. They are rocklike in nature and usually extracted by opencast mining (quarrying).
  5. Natural sodium bentonite as the name suggests occurs with sodium as the predominant exchange cation. The name originates from its discovery near Fort Benton, USA. Sodium bentonites are characterized by high swelling, high liquid limit and high thermal durability.
  6. The vast majority of the montmorillonites occurring in abundance world wide are of the calcium type and referred to as calcium bentonites. The name montmorillonite originates from a discovery made at Montmorillon in France. Calcium bentonites are often characterized by much lower swelling and liquid limit values compared to natural sodium bentonite.

Mining

  1. All of our bentonite originates from India.
  2. Once the bentonite has been mined, it is then dried and finally sent to the factory for processing and packaging.

Packing and Delivery

Our Minimum Order Quantity for bentonite is 1.25MT packed into 1 Jumbo Bag. We also cater to large orders ranging from container to vessel basis

Animal feed is food given to domestic animals in the course of animal husbandry. There are two basic types, fodder and forage. Used alone, the word “feed” more often refers to fodder. Bento Feed bentonite is natural sodium bentonite which is rich in montmorillonite. Bentonite Clay is accepted as generally recognized as Safe(GRAS) as a direct food ingredient. There are various benefits of using bentonite as Animal Feed as listed below:

  • Bentonite for Animal Feed is a rich colloidal Bentonite with a mesh of 200 & above
  • Bentonite Grain Size is little coarser to spread evenly on Animal Food
  • Bentonite is able to strengthen the Egg Shell as it prevents lumping and caking via absorbing excess moisture and oils.
  • Bentonite is Non Toxic & Non Corrosive
  • Bentonite would able to Help in Better Digestion for animals such as Dogs & Cats

As Deltacorp is an authorized supplier of bentonite, it carry various types of bentonite that is of used for numerous construction activities such as GCL.

Bentonite is widely used for GCL. The primary usage of Bentonite in GCL is to obtain low hydraulic conductivity. In order to obtain, several factors has to be taken into account as per below:

  • Clay Quality of bentonite
  • Amount of bentonite Clay Used Per Unit
  • Uniformity of bentonite

Bentonite is also used for various purpose for Geosynthetic Clay Liners construction. DELTA CORP SDN.BHD is a premier bentonite supplier for GCL uses. The company have supplied bentonite to various construction firms in Malaysia for major projects

Use Of Bentonite

  • Bentonite affixed via stich-bonding provides additional internal resistance to shear in the clay layer.
  • Bentonite as a primary ingredient and affixed by needle-punching to a woven or non-woven upper geo-textile
  • Bentonite as a Primary Ingredient mixed soluble adhesive to a woven upper and lower geo-textile
  • Bentonite as a Primary ingredient mixed with an adhesive and bonded to a blend of high & low density.

During Boring/ Drilling of pile, the side of the bore hole is subjected to various types of force and pressure like

  1. Active earth pressure
  2. Overburden Pressure
  3. Hydrostatic Pressure
  4. Pore Pressure

Functions of Bentonite for Drilling

Bentonite is used various applications of drilling as per below mentioned. This is due to Thixotropic property of Bentonite suspension, it permits the material to have consistency of a fluid when introduced into the excavation & when undisturbed forms a jelly

Deltacorp is a Bentonite supplier for drilling.

The Applications that can be used

  • Bentonite is able to seal the borehole walls, to remove drill cuttings, and to lubricate the cutting head.
  • Bore hole scavenging for salt water and sweet water.
  • Bentonite can be used to reduce Drill Fluid Formation
  • Used where pipe jacking technique is employed especially micro tunelling & HDD ( Horizontal Directional Drilling)
  • Underground mining
  • Bentonite can be used for River crossings to reduce seapage losses
  • Coal-bed methane drilling
  • Curb-to-house installations
  • Surface coring jobs
  • Under-highway boring

Advantages:

  • Fast and easy mixing Of Bentonite enable faster approach to construction Jobs
  • Bentonite is able Stabilize the bore hole upon discharge of Drilling Equipment
  • Develop good suspension at lower dossage
  • Control loss of drilling fluid.
  • Carry rock cuttings to the surface and leave them there.
  • Caviteness: fill the bore hole without cavities
  • Quick hardening quick thixotropy ensures cavity bridging.
  • Plasticity: permits static safety of the GSHP even in case of specific geologic activities

Bentonite for Oil & Gas Drilling

Bentonite is mainly used as a drilling mud & part oil-well cement formation.

The best type of bentonite is obtained via bentonite that has high sodium montmorillonite.  If a bentonite does not have a high sodium montmorillonite, the filter cake permeability, viscosity build-up will be adversely affected especially when bentonite is used a drilling fluid.

A bentonite with the required specification for the oil & gas industry will be able to provide

  • Lightweight cementing system
  • Bentonite is able to provide Good fluid loss control as seepage from landfills must be collected and properly disposed
  • Good rheological properties
  • Adequate compressive strengths
  • High Plasticity
  • Absorb large amount of Water

Bentonite, when mixed with water, forms a fluid that is pumped through the drill stem, and out through the drill bit. It then extracts the drill cuttings from around the bit, which are then floated to the surface.

The drilling mud or Bentonite NP40, or gel also serves too cool and lubricate the drill bit as well as seal the drill hole against sea page and to prevent wall cave-ins.
