Beneficiation Studies of Halloysite and Halloysite/Kaolinite Ores from Northwestern Anatolia
2012In this study concentration of halloysite and halloysite/kaolin ores from northwestern Anatolia was investigated by wet high intensity magnetic separation and acid leaching methods. It was found that the acid leaching is the most effective method for the removal of primary coloring impurities such as limonite. However it is considered that fine grained

Halloysite -A critical assessment
1990Water enters the interlayer space in halloysite to minimize cation-cation Coulomb repulsion between adjacent layer surfaces and to coordinate exchangeable cations postulated as present to compensate for Al(IV). The layers roll into tubes due to lateral misfit between a larger tetrahedral sheet and a smaller octahedral sheet. Tetrahedral rotation, which
