Show UTAH COPPER CO. I Always interesting to the Salt Lake public, the , ' ! improvements at Garfield have become doubly so i . since the late unpleasantness between the valley ;' farmers and the smelting companies resulted in 1 ' a writ of injunction from Judge John A. Marshall j I , jm admonishing the companies to stop smoking in the i ! 'H presence of agriculturalists. "What will the copper mines do now?" was tho question heard on every hand when the news of the decision came out. The Utah Copper com-pany com-pany was ready with an answer. It pointed to its ' now plant, now practically complete, at Garfield, j and the management congratulated Itself on its wit in making timely provision for a condition of 'M things that could be but dimly foreseen when its first steps were taken. r 1 With a mill capable of reducing its immense ' ' 'M tonnage of low grade copper ore and the new j plant of the American Smelting & Refining Co. j waiting next door to thaw the metals out of the 1 concentrates, the Utah Copper is entirely immune J from the agrarian problem. This company is i really the creator of Garfield. Its officers con- ' celved the idea of acquiring ground and water rights far from tho maddened crowd, and quietly H put through the negotiations that made possible iH the Garfield of today. They had the wisdom to jB get plenty of ground while they were about it, B and when the American Smelting & Refining Co. 1 jH went looking for a lodge in some vast wilderness ' JH to establish an ultra copper plant they found the ' H Utah Copper pre-emption waiting for them. ;- ffl The Boston Con., which had projected a town H at Pelican Point, finally driven to desperation by H the demands of blackmailers, turned to the Gar- h field reserve and was hospitably told that "there I is always room for one more." It was in this 9 manner that the foundations of a flourishing in- dustrial community were laid. I At this favorable spot the Utah Copper Co. I has constructed during the past year a concentrat- ing mill that embodies the crowning achieve- n ments of milling experts in all parts of the world I selected after thorough tests because of their fl adaptation to the ore to be treated. The dimen- sions of the plant are given in acres, instead of fl feet. The main building and ore bins keep the H rain off 7 acres. The shops, warehouses, yards, H reservoirs, etc., cover 20 acres more. In the main fl building are approximately 8 acres of floor space. H Of this 5.6 acres are for the accommodation of the fl concentrating machinery, divided into three ascending levels. The concentrating floors, by the way, are of reinforced concrete. When the crude ore first arrives from the mine it is received in a bin with a capacity of 46,000 tons. Another bin affords accommodations for 14,000 tons of crushed ore, a total binnage of 60,000 tons. In designing the plant the management manage-ment adopted what is known as the "unit system." sys-tem." Each of the two sections already installed ha a daily capacity of 3000 tons and is entirely independent, and each section is divided into six partially Independent units. This plan assures the continuous operation of the plant, for should one unit have an accident the others would not be affected in the least. The process employed Includes two distinct operations. op-erations. The first is the crushing process by which the mineral-bearing rock Is reduced to such small pieces that the metal particles are released from the waste. Each unit, or section, has two No. 1 gyratory crushers and each of these crushers has a capacity of 100 tons an hour. The gyratory crushers are augmented In each department depart-ment by two 54x20 roughing rolls. When the ore loaves the coarse crushing department it Is reduced re-duced to one-quarter inch size dry. A single battery bat-tery of fine-crushing machinery completes the preparation of the ore for the concentrating processes. proc-esses. This final grinding is to be accomplished by 36 6-foot Chilian mills and 24 sets of 16x36-inch 16x36-inch crushing rolls with such necessary accessories accessor-ies as feeders, elevators and screens. When released by grinding the pulverized metal, with the accompanying waste, is passed on to the concentrating department. It is up to that department to separate the two. The concentrating concentrat-ing machinery will consist of 72 jigs, 48 Wilfley tables and 1104 6-foot vanners of the suspended type, the latter being a modification in some respects re-spects of the Johnson concentrator. For the ore that requires it there will be provided 24 quadruple quad-ruple compartment classifiers as well as the 384 9-foot conical settling tanks. The heart of the plant is the power plant, a mammoth institution which will be required to run the mine and mill at Bingham as well as the Garfield Gar-field works. In the form of electricity the power will be carried over a wire for 17 miles to the Bingham end. Twenty water tube boilers are being installed. Under the conditions which will prevail each boiler will be able to generate 600 horsepower. The entire set will, therefore, provide energy equal to the combined efforts of 12,000 horses. Next In Importance to the boilers are the engines. Five of these of the reciprocating pattern will apply ap-ply the power to high potential alternating current generators by a direct connection. The total engine en-gine and generator capacity contemplated will be 0750 kilowatts, or 18,000 horsepower. The great difficulty in adapting the Utah des- ft erts to smelting and milling enterpriaes is the fl lack of water. It is, therefore, interesting to note H the manner in which this matter has been handled han-dled by the Utah Copper Co. On the slope above the plant two storage reservoirs have been constructed. con-structed. One of these is 380x180 feet and will hold six million gallons. The second, with a capacity ca-pacity of about half a million gallons, is above the other and Is intended to furnish strong pressure when a heavy head is needed. Ample provision has been made for a water supply and the liquid will be raised to the tanks by three electrically driven, direct connected turbine pumps having a combined capacity of 10,500 gallons a minute. Of the ore which is to supply this magnificent plant little need be said. Every newspaper reader will remember the astonishing results that were obtained when the Guggenheims probed the territory terri-tory of the company at Bingham with diamond drill. A whole mountain was shown to be impregnated im-pregnated with copper. Some of the ledges were very rich, but the feature that awakened the enthusiasm en-thusiasm of all practical miners was the immense quantity of low grade porphyry which began at grass roots, expanded in every direction and went to an indeterminate depth. Everyone realized that a few cents on every ton would soon accumulate accumu-late a mammoth fortune. Henco se devices to save pennies and fractions of nies in the treatment of the output. Nor h wo the benefits of email economies been overlooked at the mining end of the game. Immense steam shovels working in an artificial crater are literally digging up the scenery and dumping it into a hole at the bottom of the funnel, where it is caught by electrically-driven electrically-driven cars and whirled away to the bins at the mill. The amount of ore that can be handled in this wry is a revelation to those who are fainililir only with the old-time methods of mining. Thus far the improvements adopted by the Utah Copper Co. have not progressed sufficiently to make much of an impression on the copper output out-put of the state, but the effects will be clearly manifested during the coming year. t |
