Answer:

Individual lanthanides are separated by a suitable physical method. The anhydrous fluorides and chlorides are heated under argon atmosphere in presence of calcium at 1270 K to get the individual metal. The pure metal is obtained by heating the trifluorides of lanthanides in the presence of calcium and lithium.
