Book excerpt: Excerpt from Lead Poisoning in the Smelting and Refining of Lead The last 15 or 20 years have seen great changes in the lead smelting industry of the United States. As transportation has improved, small and poorly equipped smelters which had been built near the deposits of ore have been abandoned and the tendency has been to concentrate the work of smelting and refining in a few large plants, for it has proved cheaper to ship the ore to large centers where labor is abundant, than to do the smelting in the mining districts. This change has resulted in a twofold advantage to the worker. In the first place, as these large plants are usually equipped with the latest and best machinery the amount of handwork required has been materially diminished. In the second place, the conditions under which the employees work have been improved, for large, well-built factories are usually freer from dust and fumes than are those of the old type, and newer methods of manufacture involve economies, such as the saving of poisonous volatile products which used to be allowed to escape into the air. Along with the improvement in equipment, there has been in recent years evidence of a greater interest on the part of the managers in the health and safety of their workmen, and there is probably now no plant in the United States in which some effort is not made to lessen the dangers of lead poisoning as well as to prevent accidents. As a result of these changes in most places where lead smelting is an old industry, as in southeastern Missouri, Pueblo, Denver, Leadville, East Helena, Omaha, and South Chicago, the opinion is general among physicians and townspeople, as well as among the men in the industry, that lead poisoning is far less frequent and less severe than it used to be.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lead Smelting and Refining: With Some Notes on Lead Mining Tms book is a reprint of various articles pertaining especially to the smelting and refining of lead, together with a few articles relating to the mining of lead ore, which have appeared in the Engineering and Mining Journal, chiefly during the last three years; in a few cases articles from earlier issues have been inserted, in view of their special importance in rounding out certain of the subjects treated. For the same reason, several articles from the Transactions of the American Institute of Mining Engineers have been incorporated, permission to republish them in this way having been courteously granted by the Secretary of the Institute. Certain of the other articles comprised in this book are abstracts of papers originally presented before engineering societies, or published in other technical periodicals, subsequently republished in the Engineering and Mining Journal, as to which proper acknowledgment has been made in all cases.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Metallurgy of Lead The first discovery of argentiferous lead ore was made in 1863 in Little Cottonwood Canyon, Utah; the first smelting of such ores was carried on in 1865 at Argenta, Mont; in 1867 similar ores were found at White Pine, Nev., and smelting was begun at Oreana, Nev. In 1869 the mines of Eureka, Nev discovered in 1864, were opened up, and the treatment of ores was begun in the following year. Next came Utah, where smelteries were erected in 1870, followed by Colorado, which came into prominence in 1878. Later Idaho, New Mexico, and Arizona were added to the list. Colorado for many years was the largest producer of lead ores, but it has been outranked by Idaho and Utah since the exhaustion of the wonderful mines of Leadville after 1890; it furnishes at present only 6 - 7 per cent. Of the country's product, and this high figure is largely due to the central smelting works of Denver and Pueblo which treat more lead ore mined outside of the state than produced in it. The manner in which prehistoric people extracted lead from ore is unknown. If we recall that oxide and sulphide ores readily give up lead when heated with charcoal, we can imagine that the accidental discovery of this fact may have led to the most primitive furnace, a small pit dug into the ground and enclosed by stones to form a small shaft. If at first such furnaces were worked by natural draft, blast (reeds, bellows) must have been applied to produce the temperature required to form slag. The furnaces (cavity 30 in. Deep, side-walls 26 in. High, 2 tuyere-openings) found in Sinai in which copper ores were smelted about 4000 b.c.1 had this form; the furnaces of Laurium were similar. In early times low shaft furnaces with natural or forced draft formed the ap paratus, and charcoal the fuel. Agricola2 states that in 1556 the inhabitants of the present Austrian province of Carinthia used what may be called a closed stall with inclined bottom for treating galena; they kindled a wood fire and charged the ore upon it, whereupon lead was liberated and, trickling down the hearth, was collected in a basin. Similar contrivances, the Log-furnace and Ash-furnace, were used in smelting ores in the Mississippi valley about 1720. These were in operation until 1836, when the first Scotch ere-hearth was erected. Percy' states that in 1730 the ore-hearth was in operation in Derbyshire, England.
