Copper Works in Wyoming

| The water jacket furnace, for both ! gRleDa and copper ores, built by Aessrs. | Rankin, bEaYtOu E O., oi the Pacific | Iron Works, San Francisco, nls worked a revolution ID the sneltug business of | this country. The advantage demon strated in these furnaces are facility and ! cheapness Of transportation aLd COZ | structiou, economy Jf fuel, Lueboss Of | bullion produced. and capacity for con- | tinuous and uninterrupted work. Any ore that can be sme!ted can be worked | cheaper in these furnaces than by any ! other process.
 The miuiug interests of tue country are largely InieO5ad tO the enterprise Of ' this firm for working up to such a state | Of perfection this important branch of ! mining machinery. A large number of ! companies ID New Mexico and Arizona, ] Idaho and Nevada are operating these i furnaces with satisfactory results. Be- ! iog will be f0uhd @ statement from the superintendent of .he Wyoming Copper l Company.
 FAIRBASKs, Wy. T., Feb. 2, 1SS3. MEssRs. RANKIN, BRAYrOS & Co.- Gentlemen: In answer to your Iu- | quiries as to working of orr smeiter and ny opinion as Co its merl-s, l would say [ that It has now been h operation some ! SIX weeks, and K every Way q sUccess. | The last two weeks run shows pr. duct Of nearly 90 tons copper bullIoa, running from 97 per cent. to 9S per cent.-un average Of about 6l4 tons per day. Considering the character of the ore worked, | regard this us most ex- traordiuaTy showing have had 8 long practical experience n copper smelting In various parts of the country, and an familiar wIrh the operation of
 every other style of smoker now use, but unhesitatlngly give yours tue pre- ference over all others. They are more simple Tn construction, more certain IT operation, need less attention and are much less lIa5le t1 ,' out of order and require repair. The latter advantage 1 regard as mainly attributable to yOur
 patent device for promoting the circula-
 tlOn Of Ehe water n tEr Jacket, which
 efectually prevents tue formation of scale on the inner surfaces of the Hates,
 an invariab!e result Tn all otAe- j .cket~,
 attended with the frrqucl- Jurung out
 of parts, and uf course tEc necessity os
 constant repair. Another p1lur. Oi
 equal importance b that the system Cf
 circulation prevents the ikstg. ca1s-d
 by the unequal expansion aud cutrac-
 ton of the joints, ia consequence of iL-
 heat not being properly carried off and
 distributed. The value Of ta.s feature
 of your water jackets for permanent
 work cannot be oyerestiml.eI.
 The economy with which works of th.s
 kind can be operated, 1t k well known.
 depends largely upon coatiuu1us and
 fa- A
 not be put out of bias, for E sIugIe day
 without a heavy loss Tn actual running expenses, besides the loss of the usual product. Considering tine expense and inconvenience attending the iEterruq- ton necessary for repair in th.s class of work, the value of such 6 form of con struction as will GvOid 1t is most appgr- ent. Anothe- matter of importance Is the application and distribution of q @ blast c. the charge, winch prevents Jhe great waste Ot fuel so common to ether sme!ters. Economy Of operation is not only distinguishing feature of this smelter as to fuel and general results, but also as to clOsenes5 of working my slag ordinarily showing a loss of less than one per cent from the assay value of the ore. l feel warranted in saying that you have solved the problem of working cheaply all classes of copper ores, and that the wonderful develop ment of the copper interest m this cOuu- ! try during the past few years is largely. l if not wholly, owing to the invention and ! general adoption of yoGr system of | working. C5ngratulating yen upon the ! success attending this frs: attempt at l copper smelling in Wyoming, am yours ! respectfully, 4. J. KoUIsroNE,
 perintenGeut of Furnace.
