An Introduction to Geology 2017-01-01T00:00:00Z Eventually, the broth solidified, becoming ore layered with interlocking veins of quartz, chalcopyrite, and other minerals. Héctor Tobar: How the Chilean Miners Survived 2014-07-07T04:00:00Z This defective chalcopyrite layer leads to more pronounced rollover and crossover signatures in J–V curves. Materials interface engineering for solution-processed photovoltaics 2012-08-15T17:22:03.163Z Regular intergrowths of crystals of totally different substances such as staurolite with cyanite, rutile with haematite, blende with chalcopyrite, calcite with sodium nitrate, are not uncommon. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 7 "Crocoite" to "Cuba" 2012-01-22T03:00:24.397Z The researchers then printed chalcopyrite onto the surface of the cell, applying a technique similar to a common inkjet approach, but with a special type of ink. Inkjet printing for solar panels 2011-06-30T14:54:23Z Owing to the frequent presence of mechanically admixed chalcopyrite and chalcocite, the published analyses of erubescite show wide variations, the copper, for example, varying from 50 to 70%. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 7 "Equation" to "Ethics" 2011-02-27T03:00:31.973Z Blende occurs in metalliferous veins, often in association with galena, also with chalcopyrite, barytes, fluorspar, &c. Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 1 "Bisharin" to "Bohea" For example, all the specimens of bornite and pyrrhotite examined yielded sulphuretted hydrogen with tartaric, citric, and oxalic acids, but chalcopyrite and pyrite do not. The Galaxy, April, 1877 Vol. XXIII.—April, 1877.—No. 4. There it forms a large deposit, in a granitic vein running through gneiss, and is accompanied by quartz, siderite, galena, blende, chalcopyrite, &c. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 7 "Crocoite" to "Cuba" 2012-01-22T03:00:24.397Z The team used chalcopyrite - a material composed of copper, indium, gallium and selenium and also known as CIGS. Inkjet printing for solar panels 2011-06-30T14:54:23Z Next to chalcopyrite, copper-glance is the most important ore of copper. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 3 "Convention" to "Copyright" The cobalt ores at these localities occur with pyrites and chalcopyrite as bands in gneiss. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 5 "Clervaux" to "Cockade" Copper is known to be taken into solution as copper sulphate at the surface, and to be redeposited as chalcocite where these sulphate solutions come in contact with chalcopyrite or pyrite below. The Economic Aspect of Geology The copper deposits are mainly in well-marked fracture planes in serpentine; the ore is pyrrhotite, with or without chalcopyrite. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 7 "Crocoite" to "Cuba" 2012-01-22T03:00:24.397Z The common are is chalcopyrite, a copper sulphide; that is, it is composed of copper and sulphur. The Western United States A Geographical Reader Basalt with traces of chalcopyrite.—L. C. G.—They are fossil sharks' teeth, common in marl beds.—J. E. C.—1. Scientific American, Volume XLIII., No. 25, December 18, 1880 A Weekly Journal of Practical Information, Art, Science, Mechanics, Chemistry, and Manufactures. Much of the copper of commerce is made from chalcopyrite and bornite, and these ores are more difficult to work. An Elementary Study of Chemistry Not only has the process been duplicated in the laboratory, but the common coating of chalcocite around grains of pyrite and chalcopyrite below the water level indicates that this process has been really effective. The Economic Aspect of Geology Ellenville Lead and zinc: zinc blende, chalcopyrite, galena, lead, zinc and copper concentrates Empire China Works, Brooklyn Insulators Empire Gas and Fuel Co., New York at the Louisiana Purchase Exposition, St. Louis 1904 Report of the New York State Commission In places the chalcopyrite has been changed to the delicate green carbonate of copper called malachite. The Western United States A Geographical Reader Examine brimstone, flowers of sulphur, pyrite, chalcopyrite, sphalerite, galenite, gypsum, barite. An Introduction to Chemical Science The natural inference was that as the veins were followed deeper the proportion of chalcocite would rapidly diminish, and that a leaner primary zone of chalcopyrite, enargite and other primary minerals would be met. The Economic Aspect of Geology Below this is a zone carrying copper in the form of chalcopyrite, enriched by chalcocite deposition from above, ranging in thickness up to 400 feet. The Economic Aspect of Geology The primary ores consist of pyrite, chalcopyrite, and other sulphides, with large amounts of jaspery quartz and some calcite and dolomite. The Economic Aspect of Geology The primary deposition was of chalcopyrite and other copper sulphides, together with garnet, diopside, and other minerals known to have required high temperature in their formation. The Economic Aspect of Geology Examine native copper, chalcopyrite, malachite, azurite, copper acetate, copper nitrate, copper sulphate. An Introduction to Chemical Science The most abundant compound of Cu is chalcopyrite, or copper pyrites, CuFeS2. An Introduction to Chemical Science The ore body grades below into a zone characterized by lean chalcopyrite, which is supposed to represent original or primary deposition from hot waters associated with the porphyry intrusion.
