Bentonite clay powder is a product of drying and fine grinding of natural material – clay, which has retained all its colloidal-chemical properties. It is widely used in the national economy:
in the mining industry – for the preparation of drilling fluids;
in foundry – as binding additives in the production of molding sands;
in ferrous metallurgy – for pelletizing iron ore concentrate;
in ceramic production – to impart high strength to products;
in construction – for the production of high-quality expanded clay;
in the food industry – for the purification of liquids;
in medicine and pharmacology – for the manufacture of medicines;
in agriculture – to improve the structure of the soil.
Bentonite is one of the most versatile and inexpensive natural products in which the mineral content of montmorillonite is 50% or more. From the point of view of practical use, alkaline ones are the best, since they can be used without additional processing.
