Kaolin is an important industrial mineral having numerous uses and requiring various market specifications. High brightness kaolin clays represent a continuing challenge to the producer. An advancement in this field of Kaolinite Clay Beneficiation has been a patented process developed by Minerals and Chemicals Philipp Corporation and …

Heating alone will not distinguish the dioctahedral kaolinite group minerals from chlorite because the 002, 003, and 004 chlorite peaks are also weakened by this heat treatment (Moore and Reynolds, 1997). Intercalation complexes can also be used to differentiate individual dioctahedral kaolinite minerals. For example, dehydrated halloysite can ...

WA Kaolin is strongly committed to employing local residents from Western Australia's Wheatbelt region for roles at the Wickepin Kaolin Project with the vast majority of our staff living in nearby towns and commuting daily. The project comprises four retention licences (R70/40, R70/42, R70/43 and R70/44) and a single mining lease (M70/1143).
