Claims (1)

  1. Изобретение описывает способ отделения магния от магниевого шлака, который содержит радиоактивный торий и его дочерние изотопы. Способ обеспечивает концентрирование радиоактивного тория и его дочерних радиоактивных изотопов из магниевого шлака и снижение объема радиоактивных отходов, требующих уничтожения.
