Excerpt from Practical Notes on the Cyanide Process The writer has t projected in the following pages an exhaust ive treatise on the cyanide process. Such a work will inevi tably appear when the practical operation of the process has reached a higher state of perfection, and when its very complex chemistry is more thoroughly understood. At the present time a kwledge of the details of practice in large cyanide mills in South Africa, Australasia, and the United States is somewhat difficult to obtain; the methods of operating, for which each operator claims a certain amount of originality, are, as a rule, secrets jealously guarded, and in consequence we have a rather meager literature on the subject.
