Kaolin Beneficiation. Kaolin clay is one of the yeoman minerals. It sees duty in almost every aspect of our lives:-in and on most paper products (from modern newsprint to National Geographic and packaging board) sometimes as much as 25% (by weight) of the product, 40% of the tile (ceramic, rubber, and linoleum) you walk on, and …

This situation necessitated beneficiation of phosphate-rocks ; first on Florida phosphate fields in early 1900s. The latest Figure (3) of world production of this vital raw material in 1984 is 134,321,000 tonnes, to which United States' contribution alone is about 32%. Fortu-nately in recent years phosphate industry had made a head way in India.

The document characterizes a kaolinite clay from Assam, India. It finds the clay contains quartz and siderite impurities. Wet sieving removes most quartz and iron impurities.
