We expect shortly to
hear of the practical introduction on a large scale of Mr. Molloy's
process, and we look forward with interest to the results which may be
obtained from it.--_The Engineer_.

TREATMENT OF ORES BY ELECTROLYSIS.
By M. KILIANI.
The author lays down general principles for electrolytic metallurgy.
Ores must be distinguished as good and bad conductors; the former
may serve directly as anodes, and are easily oxidized by the
electro-negative radicals formed at their contact, and dissolve readily
in the electrolyte. The bad conductors have to be placed in contact
with a conducting anode, formed of an inoxidizable substance, such as
platinum, manganese peroxide, or coke. In laboratory experiments a good
conducting ore is electrolyzed by suspension from a platinum wire in
connection with the source of electricity, and is then immersed in the
bath. On an industrial scale the ore, coarsely broken up, is placed in
one of the compartments of a trough divided by a diaphragm.
