TLDR
In this paper, a column packed with activated alumina was used to remove trace impurities of iron, copper, silver and lead from zinc, cadmium, manganese, magnesium, calcium, strontium and barium salts.Abstract:
Solutions of zinc, cadmium, manganese, magnesium, calcium, strontium and barium salts and of ammonium and sodium tungstates have been freed from trace impurities of iron, copper, silver and lead by one passage through a column packed with activated alumina. In most cases, the contamination in the resulting solutions is below the limits of polarographic or photometric analysis.read more

Chromatography in the preparation and purification of materials.
TL;DR: The criterion of a preparative method in this review is not only its suitability for use on a large scale, but also its applicability to the separation of the material in a highly pure state with a high recovery yield, especially in the case of rare and expensive materials.
