The behaviour of REE + Y during kaolinitization was found to be largely a function of pre-alteration mineralogy. In the examples studied, i.e. granite-derived deposits of ...

Clay

Clay is a mineral formed from the weathering and transportation by water of parent rocks which are deposited in ancient river basins from where it is now extracted. In Refractory application, it is used either as a binder for refractory brick production, or as additives to improve plastic behavior during installation.
