Book Description
Excerpt from A Handbook of Gold Milling The process of differentiation, so essentially characteristic of all modern development, has of recent years extended very markedly into the province of the gold-miner. The time is not so long past since any ordinary miner was considered to be quite capable of taking a shift in the mill, and it was looked upon as part of his duty to be equally useful above and below ground. This state of things did well enough as long as rich reefs or rich portions of reefs, such as the superficial portions not uncommonly are, were alone worked; enough gold was won to more than pay expenses, and no one knew or even seemed to care how great the loss might be in the mill.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1894 edition. Excerpt: ... with advantage be made of wooden staves held together by a couple of iron hoops. At times the pavement of the arrastra is well below the surface of the ground, and then the lower part of the walls may simply consist of clay well beaten down. Wooden staves form, however, the most satisfactory wall, the height of which generally varies between 1 foot 6 inches and 4 feet 6 inches. The pavement must consist of blocks of hard stone, carefully dressed and jointed, and laid as evenly and as closely together as possible. The depth of the pavement is usually between 1 and 3 feet, and the stones between 6x6 inches, and 12x12 inches in area; the larger they are, the better. The joints should be filled with good cement, or failing this with very fine sand, worked in as thoroughly as possible. The best material for the pavement is probably a fine grained basa

Book Description
Excerpt from The Stamp Milling of Gold Ores The matter thus collected is rather a painstaking description of practice than a discussion of the chemistry and mechanics of the stamp-milling process. It Will, therefore, it is believed, be serviceable to those engaged in the actual work of the mill, no less than to the student in the laboratory or lecture room.

Book Description
Excerpt from Handbook of Milling Details: Compiled From the Engineering and Mining Journal This book is a collection of articles that have appeared in the Engineering and Mining Journal during the last two or three years under the general head of "Details of Metallurgical Practice," a department of the Journal that has been appreciated highly by its readers, many of whom have expressed the wish that a collection in book form be made, which has now been done. The character of this book is in all respects the same as "Handbook of Mining Details," published in 1912, and it is difficult therefore in this preface to add anything to what was said in the preface of its forerunner, wherefore some paragraphs of the latter will simply be repeated. In the editing of this volume, the work has been chiefly in the selection of the material and its arrangement in chapters. Now and then it has been possible to excise some paragraphs as being unessential and occasionally the phraseology of some articles has been altered a little, the requirements of preparation for the original weekly publication not always having permitted leisurely consideration; but in the main, the articles now presented in this book are as they were given in the pages of the Engineering and Mining Journal. However, it has been necessary in a few cases to reduce the size of the engravings. In making this collection the limitation of space necessitated the rejection of all material that did not pertain to the subjects selected for the chapters of the book, and even so it was necessary to dismiss some of the longer articles pertaining to them, which approached the character of essays rather than being the description and discussion of details. The present compilation covers the publications in the Engineering and Mining Journal from November, 1909 to December, 1913, inclusive. No claim is made that this book is a treatise, exhausting its subject, or any part of it. It is simply a handbook that is a more or less random collection of useful information, being just what passes through the pages of the Engineering and Mining Journal in the course of a few years. No special attempt to round out any subject has been made. Yet it will be found that many subjects are well, if not fully, treated. With regard to the authority of what is to be found in these pages: The matter in the main is merely descriptive of what is done. Nevertheless, there is frequently the injection of opinion and advice. A great technical journal is directed by its editor and is shaped by its editorial staff, but it is essentially the product of its contributors.

Book Description
Excerpt from On the Milling of Gold Quartz Dear sir My last paper to the State Geological Society on The Milling of Gold Quartz, wherein I tried to describe the process of simple amalgamation of the raw pyritic matter in wooden barrels, appears from the great number of letters that I have received respecting it, after its publication in the Mining and Scientific Press, to have attracted considerable attention, and has, therefore, encouraged me to resume the subject, but this time as a contribution to the State Mining Bureau; you having kindly offered to allow the specimens accompanying this paper, and intended to illustrate whati have stated, to remain for a short time at the rooms of the Mining Bureau, to give those who feel interested in the mat ter a chance of examining them. You have also promised to put some very important and interesting specimens from your private collection with them. I can only now repeat what I have stated on a former occasion, that at the present time I think scarcely anything can be of greater importance to the mining interests of this State, than a simple and cheap mode of extracting the gold from low grade veinstone, and the determination of the true condition of the ores associated with it.
