The invention provides a process for producing a phosphate of a lanthanoid. The process is based on a two-jet precipitation, starting from separate reservoirs of a rare earth salt solution and a phosphate solution which are introduced simultaneously by separate feedlines into an aqueous acidified initial charge with stirring at a pH of 0 2 to complete the phosphate precipitation.
