Abstract :
This paper deals with a field of engineering in which electrical, chemical and metallurgical engineers are all interested, and have responsibilities. It contains a discussion of electrical power utilization developments which are based upon fundamental principles of physical chemistry and electro-chemistry. It outlines the particular functions of the electrical engineer and indicates his close co-relationship with the chemist and metallurgist in the solution of such industrial problems. It deals only with metals which are ordinarily employed in construction or manufacture and in the production of which large quantities of electrical power are employed. Smelting and electrolytic methods are compared; data and illustrations on plants and equipment for the production of iron, zinc, copper, nickel, aluminum, etc., are included.
