In an unconventional 3D format of the periodic table in which the elements are arranged on a series of stacked cylinders, lawrencium is placed under lutetium: Device for displaying an improved periodic table of the elements (1980).

It is claimed that lawrencium can be separated from other actinides by photochemical action on the actinide salts: Photochemical separation of metals in solution by precipitation following reduction or oxidation (1979).

It is suggested that lawrencium, like other actinides, may form compounds with carbon monoxide or hydrogen or ammonia; these compounds may then be useful in separating mixtures of actinides: Actinide Compounds With Ammonia Or Co And H (1973).
