concentration cent ration in a 2000 ton plant near great salt lake on account perhaps ot of the novelty ot of the scheme and the initial outlay required delamar balked and surrendered his bis option jackling persisted experimental data was verified and colorado capitalists came to his A pilot mill at copperton hopperton Cop near the mouth ot of bingham DIng liam canyon was completed in 1901 it returned a profit but tonnage to justify a investment Invest mentin la a commercial plant remained to be demonstrated drill tests in 1905 having proved 20 million tous tons of 0 I 1 copper ore the capital was provided slid and utah copper became a going concern since then hundreds ot of millions ot of tons have been added to the original ore body by economies in treatment ot of success successively liely lower grades ot of ore lengthening by many years the lite life ot of the mine A 20 mile railroad to transport ore from tile the mine to the mills was built in the mills gravity concentration has been replaced by notation flotation the steam shovels have been converted to electric shovels capable of loading a ton car in 5 minutes minute and the mine haulage system has been I

adare prior to 1312 1912 common labor is un lit supplies taxes etc have also followed the same trend it la Is apparent pi rent therefore that an aggressive policy of 0 continually improving methods and equipment must be the rule other otherwise wige the foka olag factors would torce force the ing of 0 the ore body that Is in selecting the high grade ores such a procedure would materially reduce the life ot of the mine with consequent loss to stockholders and mole serious a loss to the community in payrolls supply purchases and taxable wealth |
