Show "* Increase in the production of these octala with the exception of ' zinc is not to be locked for* The production of sine on a large scale began toward the evA of 1? 24, and with the return of normal business conditions it is likely that there will be considerable increase in its out put, Until this year ( 1? 33) all of Utah* a non- ferrous metals left the State in crude forn with the exception of the war period of fancy prices when some metallic zinc was produced,, This operation ceased, aoweverj, with the return to normal nrices on account of the high coat of power- Copper leaves the State in blister form containing the silver and goldfound in the ore with it, Most of the lead leaves in thefora > €> t base bullion with the associated gold and silver values, while the zinc goes out as a sulphide concentrate assaying 50 to 60* metalo Copper and zinc are refined by electrolytic methods and consequently electric power is a major item in their further processings Approximately 3500 K. Wo hours are required to produce a ton of zlno from concentrate, and the labor of 2,5 nen for one day* In the year 192? r, we find about 36* 000 persons engaged, in the smelting and refining of copper, leads zine9 silver and gold in the United Stateso Exclusive of aluminum,, about 235 000 persons were engaged in C ^ nionferrous metal manufactures - lot us say about 280D000 workers all told. Limits are rately attainable, but they should always be examined. Roughly speakingt Utah produces one- seventh of the nation's noa « ferrous metals,.

Investigation shows that for each worker in industry in the State, there is a total dependent papulation of 14 persons. Hence, if we were to tura all of our metals into finished products we could support an additional 5& 00000 people or more than double our present numbero This is the Unit for out present product! on* However, it is vary doubtful whether we have enough water to support so many, even though economic |
