If, therefore, it is possible to keep the mercury bright and active, as may be done by adding chemicals, a larger percentage of precious metals can be recovered.

DOWNLOAD EBOOKExcerpt from The Metallurgy of the Common Metals: Gold, Silver, Iron (and Steel), Copper, Lead and Zinc Since 1913, the date of the last edition, such radical changes and improvements have been made in the-metallurgy of the common metals, that this edition of 1921 has been largely rewritten to bring it in accord with present practice, as will be seen by examination of the following pages. Great pains have been taken to clearly set forth underlying principles and at the same time to give the details of methods and of metallurgical equip ment, and their cost. It is realized that, due to the rapid advance in prices, the costs of operation have lately been subject to serious modification. A chapter has been devoted to questions of the economic situation of the business of metallurgy. Little attempt has been made to describe methods not now in use.

DOWNLOAD EBOOKExcerpt from The Metallurgy of the Common Metals: Gold, Silver, Iron, Copper, Lead, and Zinc This outline of the metallurgy of the common metals, namely, gold, silver, iron, copper, lead, and zinc, is devoted to the description of processes for winning these metals from their ores and then refining them. The metallurgy of iron is treated only to the point where pig-iron is obtained. Following the description of ores, as well as of the fuels used in smelting them, and the materials of which the furnaces are con structed, we come to sampling, for the determination of the exact value of the ore before treatment. A chapter has been devoted to the subject of thermo-chemistry as applied to igneous methods of extraction. The winning or reduction of' the various metals is then taken up in order, and is followed by. A description of the methods of refining them. Attention is then given to commercial considerations, since the processes must be conducted in a profitable way.

DOWNLOAD EBOOKExcerpt from Handbook of Metallurgy, Vol. 1: Copper, Lead, Silver, Gold IT is a curious fact that there does not exist in the English language a single complete treatise on Metallurgy. There are a number of smaller text-books, mainly adapted to the use of students, which cover the entire field, but make no pretence of describing it with any thoroughness of detail; and there are a number of very admirable works dedicated to the metallurgy of individual metals. Had my respected teacher, the late Dr. John Percy, ever carried out his magnificent idea of a comprehensive series of volumes on this subject, the ideal of. An exhaustive work on Metallurgy would have been produced, although its bulk would have attained the formidable dimensions of a small library in itself - an advantage perhaps to the specialist, but a less commendable feature for those who have to deal with general Metallurgy. Such being the position of our literature of this subject, I venture to think that I am rendering the English metallurgist a distinct service in submitting to him a translation of the most recent and most exhaustive work on the subject in any language, from the pen of that eminent metallurgical authority, Dr. C. Schnabel, of Clausthal. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The slope or angle of the bosh-wall must be such as to give proper support to the charge, which rests upon it, and yet allow the solid coke to slip down; an angle of 80 is preferred. The height is limited to the height of the smelting zone. These conditions limit the diameter of the bosh to 22 ft. From the top of the bosh the stack wall must decrease in diameter to the throat to give room for the descending charge to swell by reactions that occur in its downward progress. This leaves, at the throat, a diameter suitable for the proper distribution of charge. Furnaces have been built higher than 100 ft., but such height has been found to be excessive, especially for fine ores; and the best practice calls for 90 ft. or less. GAS CLEANING The top gas coming away from a blast-furnace, especially when smelting fine ore, carries much dust caused by the agitation of the blast. Some of this is settled out in the dust-catcher, but the gas still remains quite dusty. When the gas is subsequently burned at the stoves the dust settles in the checker work and at the boilers it attaches itself to the stoves. If the gas is cleaned it burns more efficiently and, moreover, it can then be used for driving a gas-engine blower plant. Fig. 157 gives the views of a scrubber plant for gas cleaning for stoves and boilers for two furnaces. Of the figure, W, is a front elevation, X, a side elevation, Y, a separate elevation of the dust-catcher, and Z a plan view of one of the scrubbers, to show the arrangement of the water sprays.
