A method for separating the isotopes of an element comprises the passing over a mass of highly magnetizable particles of fluid (either a gaseous mixture or a solution) containing an element or its compounds or ions each containing a single atom of the element to be isotopically separated. A strong magnetic field is utilized to magnetize the mass of particles and while the particles are magnetized the isotope having the higher magnetic moment is concentrated within the mass in the high magnetic field gradient zones at the points of contact between the particles. The less magnetic isotope flows through the matrix and the fluid emerging from the mass is collected in a suitable container. The magnetic field is removed intermittently and the fluid then flowing through the demagnetized mass is directed into a different container which thus collects the isotope having the higher magnetic moment and which is free to flow out with the fluid upon demagnetization of the mass. A second method is a batch method which includes the step of using a flushing fluid which does not contain element. A third method is a continuing process using a moving series of treating chambers.
