The copper era and Morenci leader., 1912-01-12

& Refining Co., This will be ready fol operation about April, 1912. The de development and blocking out of ors was continued, especially by the Ray Consolidated and Ray Central com panies. -,. .s-, :4f,!t - Montana
 The copper production in Montana will probably fall 10,000,000 to 12,000, 900 pounds short of the output of 2S5, OO0,O00 pounds in 1910., This de crease is due to the policy of curtail ment adopted by the companies in the Butte district.
 Extensive development was carried on in the Butte district and especial attention was given to improving the mine equipment of the units compos- ing the Anaconda Copper Go. This included the extension of the use of electric and compressed air power, i'm provement in ventilation, etc. These improvements are expected to mate rially reduce the cost of producing copper.
 Michigan
 The production from Michigan rank ing third among the copper-producing States, will probably show a decrease of about 5,O00,000 pounds from the production of. 221, ,462, ,O00 pounds in 1910. This decrease can be attributed to the relatively. low price. of copper, which. caused some companies either to suspend operations or to produce below their maximum capacity. No unusual developments took place in the State during the year; though sew eral mines that have been under .des velopment made small productions
 Utah. A
 ,I, <xf ;v, Ifoh iv, 1911 will show a. decided increase over. the output of 125,1S5;O00 pounds in 1910. The main output, as in previous years, was derived from the Bingham district, though the Tintic district con tributed an important amount and the Frisco district made larger produc- ton than 1910.
 The most important events. of the year affecting the copper industry in Bingham & Garfield Railway, connect ing the, mines and mills of the Utah Copper Co, and the remodelling and enlargement of this company's mills. A third unit of the Ohio Copper Co.'S mill was placed; in operation during the year. .L
 Nevada.
 The output of copper from Nevada will show a slight increase over. the 64,494 ,000i pounds produced in 1910. The main production, as in previous years, was that from the Ely district, by the Nevada Consolidated Copper Go. The smelting plant of this com pany was remodeled for the use of oil as a fuel instead of coal.
 Development was continued in the Yerington district. The Mason Val ley Mines Co. practically completed the construction of it's S00-ton smell ter at Wabuska and the smelting of ore from the district will probably be- gin early in 1912.
 California.
 The production of copper from Cali fornia will fall considerably below the 45, ,76O,000 pounds produced in 1910. This decrease can be attributed to the difficulty experienced by the Shasta County SmelterS in controlling the shelter fumes. For this reason the shelter was closed in July by order of the courts and remained closed for the rest of the year, and the Mammoth Smelter was not operat- ed at full capacity. Experiments are under way looking to the solution of the "smelter smoke" problem and it is hoped that these will prove success full, but the district will hardly show a marked increase in output for 1912.
 Alaska
 . It has been estimated by the Geo. logical Survey that Alaska mines pro- duced 22,900,000 pounds of copper in 1911. This is by far the largest out put ever made by the Territory and is due to the beginning of production from the Copper River district and the increased output from the Prince Will liam Sound district. The Copper Riv- CT Railway was completed to the Bo- nanza mine and shipment of ore be- gan in April and continued through the year. There was also marked in- crease in output of the mines of the Prince William Sound district.
 Tennessee The output of copper from Tennes- see will show some increase over the l It, ,691,77 pounds produced in 1910. | This increase is due to the enlarge ment of the acid plants connected with the smelters of the Ducktown dis trict which permitted the smelling of more ore. The production of sulphu- ric acid is now an important factor in the smelting industry of the Duck 1 town district.
 Colorado Colorado contains no important cop per district, it's main output of copper being incidental to the production of other metal. It will probably show a | decrease of about 100000 pounds | from the 9,3O7,OO pounds produced in 1910
 Idaho The production of copper from Ida l no will probably show considerable de- crease from the 6,S77,000 pounds pro- 1uced in 1910. As in previous years the main output was derived from the Snow Storm mine, in the Occur d'Al- sne district though tho output from this mine was considerably less than | in 1910. The Lost Packer smelter, at [vers, was operated for a short time, and other districts contributed to the 1 total, for the State.
