Book excerpt: 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.

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

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Gold Mining and Milling in Western Australia: With Notes Upon Telluride Treatment, Costs, and Mining Practice in Other Fields The chief objects the Author has had in view are, first, to present a history of gold-mining in the Colony; secondly, to explain the peculiar difficulties that have been encountered in the treatment of the sulpho-telluride ores of Kalgoorlie and in dealing with other local problems; thirdly, to draw a comparison between the conditions that obtain in Western Australia and other mining fields; fourthly, to show by figures of production and facts that mining in Western Australia is on a sounder footing than is at present, perhaps, generally supposed; and, fifthly, to furnish data, particularly in regard to costs, that may serve to promote future economies by calling attention to questions that may be worth studying in this connection. A number of expert writers have dealt with matters of which this book treats, but their observations are, to a large extent, buried in a mass of literature that can only be unearthed by a large amount of research.

The blanket washings are very poor. The North Cornish mill is not in the town of Ballarat, though in the mining district of that name, but at Daylesford. The plant consists of 50 stamps, and the rate of drop varies from 70 to 75 per minute, the height of the drop being 8 inches. The depth of discharge or issue is extremely irregular. When starting with new dies or false bottoms the top of the die is approximately level with the bottom of the grating and the depth of discharge is practically nil, but as the dies wear down (they are 4 inches deep) the issue in Near the famous Canadian lead, which yielded so many of the large nuggets. creases to a maximum of a little over 3 inches. The mill crushes 90 long tons per day, or 2,450 tons per month. The amalgamation is effected by methods similar to those described as in use at the Star of the East. Scarcely 11 per cent. of the amalgam obtained comes from the mortar boxes. Much the largest proportion is derived from the skimmings of the wells and in the blanket sands. The latter are treated by Eerdan pans, of which there are six. The tailings from the Berdans go to a Frue vanner for after-treatment. This is a comparatively new mill, the oldest portion being five and the newest two years old. The quantity of ore in sight in the mine is such as to have led to the consideration of a further addition to the number of stamps. The mine has paid large dividends for alongperiod.f Notwithstanding these facts the mill is miserably incomplete.
