"Manganese" Quotes from Famous Books
 ... abundant, and Iron occurs in the form of magnetic iron ore, titanite, chromate, yellow hydrated, per-oxide and iron pyrites. In most of these, however, the metal is scanty, and the ores of little comparative value, except for the extraction of manganese and chrome. "But there is another description of iron ore," says Dr. Gygax, in his official report to the Ceylon Government, "which is found in vast abundance, brown and compact, generally in the state of carbonate, though still blended with a little chrome, ...

... of observation by descending the Alleghany River from Western New York to the Ohio. He made Pittsburgh, Cincinnati, and Louisville centres of observation. At the latter place he published in the papers an account of the discovery of a body of the black oxide of manganese, on the banks of the Great Sandy River of Kentucky, and watched the return papers from the old Atlantic States, to see whether notices of this kind would be copied and approved. Finding this test favorable, he felt encouraged in his mineralogical ...

... previously to the application of the metal cyanic, mellonic or other toning baths. Alkalies and alkaline carbonates may also be used to remove the chromic acid, and leave a subsalt, or the very stable oxide or carbonate of manganese, which may be peroxidized by the use of chloride of lime, peroxide ...

... unexploited. The minerals which are commercially valuable include gold (found in small quantities), silver, graphite, galena, pyrite, marcasite, chalcosine, sphalerite, chalcopyrite, bornite, cuprite, hematite, limonite, ochre, chromite, magnetite, azurite, manganese, malachite, gypsum, &c. The combustibles are anthracitiferous coal, coal, "brown coal" and lignite. The lignite mines opened by the government at Pernik in 1891 yielded in 1904 142,000 tons. Coal beds have been discovered at Trevna and ...

... chlorine, by the current of steam, and then condensed in a worm. Any uncondensed bromine vapour is absorbed by moist iron borings, and the resulting iron bromide is used for the manufacture of potassium bromide. The periodic process depends on the interaction between manganese dioxide (pyrolusite), sulphuric acid, and a bromide, and the operation is carried out in sandstone stills heated to 60 deg. C., the product being condensed as in the continuous process. The substitution of potassium chlorate ...

... feet, while the "low cape" is only 250 feet, and near it on the west is an elevation of 400 feet. It would be properly represented as "rather a low cape" in contradistinction to the neighboring coast. Iron and manganese are found here, and the latter has been mined to some extent, but is now discontinued, as the expense is too great for the ...

... chum," he said. "It's in the Lower Warrilow. There's a bit o' manganese down there, and they're clearing land. Plenty of work waiting. Lot of new squatters—small squatters without two fardens to rub together and make a chink. Them assisted lot. They're always glad of help, clearing scrub. They get a loand off of the ...

... it from the air? Well, there are some very complicated and difficult processes by which we can get it from the air; but we have better processes. There is a substance called the black oxide of manganese: it is a very black-looking mineral, but very useful, and when made red-hot it gives out oxygen. Here is an iron bottle which has had some of this substance put into it, and there is a tube fixed to it, and a fire ready made, and Mr. Anderson will put that retort into the fire, for it ...

... even the addition of any persalt, such as the nitrate or chloride of iron, though it improved the present color of the ink, deteriorated its durability. The author failed to procure a persistent black ink from manganese, or other metal or metallic salt. The author exhibited a series of eighteen inks which had either been made with metallic iron or with which metallic iron had been immersed, and directed attention to the ...

... the only substance employed. At Chatelperron, were picked up fragments of manganese; at Cueva de Rocca, near Valentia, pieces of cinnabar; in the Placard Cave, bits of black lead; and in the different stations in the Pyrenees, especially in that of Aurensan, ochre has been found which was doubtless ...

... forty-two, but metals, commonly so-called, number only twenty-nine. These are platinum, gold, tungsten, mercury, lead, palladium, silver, bismuth, uranium, vanadium, copper, cadmium, cobalt, arsenic, nickel, iron, molybdenum, tin, zinc, antimony, tellurium, manganese, tatiaum, chromium, columbium, rhodium, iridium, osmium, cerium. Many of these, however, are so rare, that as yet they are of no practical use. Gold has been known from the earliest ages, and is found in scales, threads, grains, and rolled masses, or nuggets, which latter have been discovered ...
