Bleaching Earth

Bleaching Earth

IndusMin Bleaching Earth, derived from the naturally occurring clay mineral Bentonite, is a powerful adsorbent, widely used for the efficient purification of crude vegetable oils & fats by the removal of undesirable odour and contaminant impurities. It is also used for the refining and decolourisation of tallow, petroleum jelly, paraffin oil and waxes

Industrial Minerals (IndusMin) is set out to rank among the top 5 suppliers of Bleaching Earth across the globe, with its manufacturing capacity of more than 100,000 metric tons per annum (330 MT/day).

IndusMin offers 4 different categories of cost-efficient Bleaching Earth for your varied requirements. For more information on grade offerings for each of these products, please refer the corresponding link:
Attapulgite/Fullers Earth is a naturally mined mineral which possesses adsorptive property which makes it a Natural Bleaching Agent. The natural mined Attapulgite is further processed to remove the impurities and improve the surface area of Natural Bleaching Earth.

Natural Bleaching Earth finds its application in purification of light vegetable oils like Palm Oil, Sunflower oil etc.

Benefits:

  • Dioxin and Heavy metal Free product
  • Has Improved Surface Area
  • Gives Long Shelf life of edible oil
  • Consumes Lower Dosage
  • Lower Oil retention in spent Earth
  • Effective for 3MCPD requirement
This is processed from naturally occurring Bentonite and Attapulgite Clay by calcining and treatment with acid to improve the surface area of the clay and consequently increasing the bleaching efficiency. The SBE finds its application in Purification of vegetable oil and fats, Biofuels and waste oils.

IndusMin enjoys access to reserves of more than 50 Million MT of high quality Bentonite and Attapulgite to ensure the uninterrupted supply of Bleaching Earth to its global customers.

Benefits:

  • Dioxin and Heavy metal Free product
  • Improved Surface Area
  • Long Shelf life for the edible oil
  • Lower Dosage / consumption
  • Low Oil retention in spent Earth
These are highly Activated Bleaching Earth grades made from naturally mined mineral Bentonite followed by the process of acid activation. The activation process increases the Surface Area thereby enhancing capacity to trap the impurities and unwanted substances. Washing Bleaching Clay removes free acidity in clay to enhance the stability and long shelf life of the edible oil. These Grades find application in purification of vegetable oils and Fat to remove unwanted impurities like gum, dyestuffs, heavy metal, color pigment and residues of crop pesticides.

Benefits:

  • High Surface Area
  • Washed Clay with Lower free Acidity
  • Dioxin and Heavy metal Free product
  • Long Shelf life for edible oil
  • Lower Dosage
  • Lower Oil retention in spent Earth
  • Effective for 3MCPD requirement
Our R&D team has developed special grades of Carbon blended Bentonite / Fullers Earth for removal of Red Units in all types of vegetable oils.

Our standardised grades are available with blends of Activated Carbon content of 5%, 10%, 15% & 20%. We can further customise to suit our customer’s specific requirements.

The high-Quality Active Carbon used by us has MB value between 90 to 100 and screen analysis of about 95% passing through 200 mesh with all extraneous material and iron particles completely removed and has very low ash content.
