A method for the gas atomisation of melts comprises delivering of molten material into an atomising vessel ( 3 ); impinging the molten material, with a jet of heated atomising gas; and delivering the subsequently solidified, atomised particles of the formerly molten material suspended in the atomising gas to a cyclone ( 8 ) for transfer to a receiving vessel ( 12 ); wherein gas extracted from the atomising vessel ( 3 ) is cooled from its extraction temperature and then at least a proportion of this cooled gas, is re-circulated and re-introduced into the atomising vessel ( 3 ). The invention also includes apparatus for carrying out the above defined method.
