• Kaolin is a clay mineral more correctly known as kaolinite. It is also called china clay. Kaolin is made up of individual crystals that form units termed "booklets" of stacked sheets.
• It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar.In many parts of the world, it is colored pink-orange-red by iron oxide, giving it a distinct rust hue.
• Commercial grades of kaolin are supplied and transported as dry powder, semi-dry noodle or as liquid slurry. It is used in ceramics, medicine, bricks, coated paper, as a food additive, in toothpaste, as a light diffusing material in white incandescent light bulbs, and in cosmetics.
• Kaolinite is one of the most common minerals; it is mined, as kaolin, in Brazil, France, Britain, Germany, India, Australia, Japan , the People's Republic of China, and the southeastern U.S. states of Georgia, Florida, and, to a lesser extent, South Carolina.
• Kaolin has a range of industrial applications, which are grouped in three main market areas; paper,ceramics and performance minerals. Demand is dominated by the paper industry, which accounts for about 70% of total sales.
• Each tonne of marketable kaolin recovered typically produces upto 9 tonnes of waste, comprising approximately 4 tonnes of granular waste,2.5 tonnes of rock waste(stent),1.5 tonens of overburden and 1 tonne of micaceous residues.Kaolin itself is used as a sustitute in filler applications.
• Korea, Indonesia, India and Thailand are also among the other largest current producers of Kaolin. In excess of an estimated 5 million tonnes of kaolin is produced in the Region from India in the west through to China, Korea and Japan in the Far East. China is obviously one of the major producers of kaolin with an estimated one and a half million tonnes mined annually from more than 600 mines.
• Japan is outstandingly important in use of high value kaolins, and around 85% of this is used in the papermaking industry in Japan. Fibreglass manufacturing in Taiwan has been also a very important consumer of imported kaolin, and it is only now that this is being stemmed, mainly by re-location of several major fibreglass producers to China.
• This trend of industrial manufacturing towards China, based on huge growth in demand for more than a decade
• The production process features the separation of kaolin from quartz and feldspar by dry and wet processing.
• The plant equipment consists mainly of: Mining equipment, crusher, roller with classifier, attritioning cells, hydrocyclones, thickener, bleaching equipment, filter press, dryer-pulverizer, bagging.
• If kaolin is heated to 800ºC, an intermediate product is formed called Metakaolin. When you add it to concrete, it acts as a pozzolan. This means it enhances the strength of the concrete, a useful property in civil engineering and oil-well cementing.
• To form calcined kaolin, however, kaolin is to continue heating it all the way to 1100ºC. Various mineral phase changes occur, and that calcining causes the kaolin structure collapses and become denser
• Flash-calcination enables the dehydroxylation of powdered kaolinite clay within several tenths of a second, when traditional soak-calcinations require minutes at least
• Processing flash-calcination in a temperature range that was determined, with a sufficient residence time, lead to metakaolins with lime reactivities similar or better than reactivities of standard metakaolin obtained by soak-calcination
