A Text-book of Experimental Metallurgy and Assaying

Abstract

THE new edition of this book conforms to the syllabus of the Lower Examination in practical metallurgy of the Board of Education. The first portion of the book consists of a series of experi ments and explanations to illustrate the reactions occurring in various metallurgical operations, while the second part deals, in quite a satisfactory manner, with elementary assaying. It would have been an advantage if the book gave a little more guidance to the beginner, for very often he does not realise the economic character of metallurgy. For instance, a student sometimes thinks that as sodium carbonate is used in the laboratory as a flux for silica, therefore it would be charged into a blast-furnace smelting copper ores when silica has to be removed. The first chapter of this book may give some students an impression of this I kind, for the substances classed as used in metal lurgical operations are not all commonly so em ployed, although frequently used in experimental metallurgy and assaying. Then, again, in the chapter “Formation of Alloys,” the theoretical quantities of the metals have been given, and no allowance made for loss in the case of volatile metals.
