Clay mineral X-ray diffraction - Wikipedia

Nonclay minerals can usually be separated by sieving samples at a small enough mesh. Samples should be lightly crushed but not pulverized because nonclay minerals will be reduced to clay sizes and become impossible to separate from the sample. Lightly crushing breaks apart the soft clays while keeping harder nonclays intact for easier removal.
