There is disclosed a process for treating a clay mineral thereby to change its rheological properties when in aqueous suspension such that the fluidity of the aqueous suspension at a given temperature and percentage by weight of completely deflocculated clay mineral solids in the suspension is increased, which process comprises the steps of mixing with the clay mineral in a plastic state a minor proportion by weight of a water-soluble organic compound having a plurality of basic groups and a number average molecular weight not greater than 1000, and subsequently or simultaneously subjecting the mixture to mechanical working under conditions such that from 25 to 1000 KJ of energy per Kg of dry clay mineral are dissipated in the mixture. |
