OF CYANIDATION BY E. M. HAMILTON, B. A. (OXON) METALLURGICAL ENGINEER, SAN FRANCISCO, CAL. FIRST EDITION MCGRAW-HILL BOOK COMPANY, INC. NEW YORK: 239 WEST 39TH STREET PREFACE The aim of the present work has been to provide in a handy sized volume a compendium of all the ascertainable facts concerned with the cyanide process that may have a practical bearing on testing an ore, planning the flowsheet and operating the plant when erected. Purely theoretical questions have therefore been kept in the background for the most part. The substance of the book is necessarily in large part a compilation and the author has not hesitated to quote verbatim from other writers in cases either where he has had no personal experience of the subject dealt with or where the matter treated of would seem to suffer in clarity and usefulness by being paraphrased or condensed. Credit has been given for discoveries and statements in every case where it was possible to ascertain their origin. Explanations of procedure have often been gone into in more detail than would have been necessary for the use of those thoroughly familiar with the working of the process, but by so doing it was hoped that the book might be found useful to the student as well as to the advanced metallurgist, and that it would find a place on the laboratory bench as well as fulfilling the function of a vade mecum for the metallurgical engineer on his travels.
