About this book
The Rare Earths addresses the occurrence, chemistry and technology of the substances named in its title. The preface describes the incandescent mantle industry's development into a prominent part of the chemical industries that may be considered essential to modern civilisation. The preface says technical development has assisted and stimulated scientific examination of the elements belonging to the group.
The mineral entry for Annerödite describes a parallel growth of Columbite on Samarskite that was once believed to constitute a new species. The account of samarium says the material of earlier chemists contained a large proportion of the terbium elements, from which a fairly complete separation was effected. The discussion says titaniferous iron ores are perfectly amenable to blast-furnace treatment and rejects the idea of stiff, troublesome slags when suitable conditions are observed.
