Bleaching Earth Manufacturing Business. Production of Bleaching Clay
Bleaching earths are generally composed of up to three types of clay minerals: bentonite, attapulgite and sepiolite. The minerals act as absorbers with capacity being dependent on mineralogical structure and properties, such as surface area, particle size distribution, porosity and surface activity.
Bentonites are a soft stone with the capacity to absorb substances dissolved in water and other liquids. The minerals have been formed over time due to the natural adaptation of volcanic ash. Bleaching earths are found in mines around the world, including North America, South America, Europe, the Middle East and Asia.
It is widely used in the refining, decolorizing and bleaching of edible oil & fats. Major demand has been experienced from Asian countries such as Indonesia, Malaysia, China, and India. Favorable government regulations and policies in these countries have had a positive influence on the market growth.
The growing acreage yield of oil seed crop and technological developments in the production process have remained key driving forces for the vegetable oil & fat industry. Growing demand for biofuel which is derived from vegetable oil is also one of the factors influencing the demand of activated bleaching earth in this industry, particularly in the developed countries.
