<p>This invention relates to a method for forming a product from a naturally occurring phyllosilicate, the method comprising the steps of: (a) exposing the phyllosilicate to a source of exchangeable cations to effect a change in the chemical makeup of the phyllosilicate interlayer by ion transfer; (b) exposing the ion-exchanged phyllosilicate to an expanding agent selected from the group consisting of a primary aminocarboxy acid, lysine orotate, and glycylglycine to expand the cell spacing and cause gel formation; (c) flocculating the gel; (d) forming a gel-floc interface; and (e) withdrawing the flocculated gel from that interface. t</p> |
