Kaolinite has a low shrink–swell capacity and a low cationexchange capacity, making it ideal for many industrial applications. Uses During 2013, 48% of Kaolin was used in paper production, and 52% was used for ceramics, light bulbs, paint, rubber, adhesives, smoking pipes, white wash in masonry, absorbents, and in soap.

WhatsApp Coal is often coated by kaolinite in flotation, leading to a decrease in the quality of clean coal. The structure of the mineral determines its properties and flotation behavior. Therefore, to remove the kaolinite from coal efficiently, the difference in mineralogical characteristics between noncoal and coal kaolinite were analyzed using advanced instruments.

· The difficulty in treating coal slime in the presence of clay minerals is well known in the coal preparation plant. Clay minerals (kaolinite, illite, and montmorillonite) have a detrimental effect on fine coal flotation because of mechanical coating and water entrainment, leading to low flotation recovery and poor flotation selectivity,.

· Coalbearing kaolinite (CBK) is a solid waste generated during coal production. Despite being a potential source of aluminum, CBK presents a great challenge in terms of Al recovery. To tackle this challenge, we used a roomtemperature mechanochemical method based on mechanical grinding and sulfuric acid treatment. Ground samples were characterized by Xray diffraction, .
