Show rat. The central power station hat not had disabling injury since March 3, 1932, and should notch it eighth consecutive unmarred year in I960. Work was started at the smelter on the broad, long-range renovation renova-tion program. Material handling equipment used at the smelter dates (great Steps Forward Taken by Utah Copper Division In Past Year back to 1906 when the plant was built, v Since purchase of the smelter by Kcnneeott in January 1959, considerable con-siderable engineering time has been directed toward designing modern material handling facilities. Construction Con-struction is expected to begin next year on this improvement. A $500,000 scrubber oystem was completed recently at the smelter. It allows the plant to reuse water needed to clean sulphur dioxide di-oxide gas. The gas, previously carried car-ried away in water, now is converted convert-ed into about 50 tons of sulphuric acid daily. Also, waste water from the plant will not carry any substantial sub-stantial amount of sulphur dioxide fumes. A 20-ton test furnace was turned turn-ed on in early November to explore the possibilities of oxygen smelting, If effective, the project will reduce furnace processing time. The smelter will produce about 222,000 tons of anode copper and 220,000 tons of sulphuric acid this year. Major physical improvements effected at the Utah refinery included inclu-ded new, dry-type dust collectors to increase recovery of values. Mechanical improvements at the concentrators include belt-type feeders for fine ore bim, an auto-malic auto-malic heating system, and automatic automa-tic control of mill pumping at Magna. At the Arthur concentrator attention at-tention centered on the experimental experimen-tal use of a rod mill for crushing ore. The 10 by 16-foot mill is being tested to see if it is more effective than the present rolls. The mill contains about I I 4 tons of 16-foot steel rods which tumble over each other to grind copper ore. Steel rods about four inches in diameter dia-meter are used. Several key management changes were made by Utah Copper Division Divis-ion during the year. J. P. O'Keefe was appointed general manager. He replaced F. C. Green, who was appointed ap-pointed asa'stant to the general manager of Western Mining Divisions. Divis-ions. In November two other important import-ant line appoints were made when O'Keefe selected Wayne Burt at general superintendent of smelting and refining and Ray Cough as general superintendent of mining and milling. O. C Madsen was promoted to division comptroller, and S. S. Wal-dron Wal-dron was moved up to Madsen's former position at assistant division divis-ion comptroller. Among experimental projects continued during the year was an improved method for leaching copper. cop-per. It utilizes research information developed at the Kennecott Re-tearch Re-tearch Center. Another good eafety record wat established through the first eleven months of I960. It is possible that the smelter will qualify for the National Na-tional Safety Council's highest a-ward, a-ward, the Award of Honor. 'The tmelter safety campaign thowt an improvement of 80 per cent over the 1959 frequency rate and 98 per cent over the 1959 severity Utah Copper Division of Kennecott Kenne-cott Copper Corporation took several sev-eral long stept forward during I960. Started during the year were a spiral drop cut at the giant Bingham Canyon mine and engineering work on renovation of the Utah smelter. Completed during the year was a $16 million facility adcing 75,000 kilowatts to the central power station. sta-tion. The projects are part of a long-range long-range program to make operations more efficient and to compete successfully suc-cessfully in the highly competitive world copper market. Utah Copper Divis'on continued to add substantially to the state's economy during the year. Total expenditures ex-penditures for the year for payrolls, pay-rolls, taxes, supply purchases and services amounted to $1 12,268,000. Thii included $42,630,000 for payrolls pay-rolls and $9,994,000 for ttate and , local taxes. More than five million tons of ore ore being removed from the bottom of the mine as the sp.ral drop cut reaches for the 5490 tun- nel, 150 feet below the level where excavation began in July on the multi-million dollar project. '' The tunnel, 5,490 feet above sea level at its upper terminus, was completed in February 1959. It will eliminate adverse haulage of ore above the 5490 elevaton. Morrison-Knudsen Company is doing the excavating. Giant machines mach-ines are used to rip up the rock, which is. hauled to a stockpile by carry-alls. There it it loaded by huge shovels unto rail cars for a downhill run to the concentrators. Only a little blasting has been needed need-ed by the contractor. The spiral will have a railbed 3,600 feet long on a 4 per cent grade. The 5490 tunnel is 17,951 leet long and ends just south of Copperton. The tunnel cost an estimated esti-mated $ I I million. Western Contracting Corporation as working on a 12 million cubic yard stripping project at the mine. This it the largest tingle stripping I project ever awarded to an outside contractor by the Utah Copper Division. Di-vision. Giant 13 cubic yard shovels and 50-ton end-dump trucks are being used on this project. Other jobs progressing at the mine include expansion and consolidation con-solidation of the central traffic control con-trol system and automation of the water distribution system used for waste dump leaching. The passenger passen-ger tram between the Carr Fork road and the mine office building will become self-operated. All salt stands that spray waste cart with a salt solution during the winter to prevent waste material from stickling stick-ling to cars are being automated. Two other projects at the mine included $284,000 during the year for electrification of switches and radio-phone systems and $184,000 for equipment for shelf dumping, which allows waste to be dumped on a shelf on top of the regular vaste dump. A bulldozer pushes the waste material over the edge. The 75,000 kilowatt addition to the central power station wat placed plac-ed in service in late October. The addition cost an estimated $16 million mil-lion and it will supply enough electricity elec-tricity for a city of 350,000 population, popu-lation, Natural gat generates the power, with coal used on a standby stand-by basis. |
