 The article ought to be of especial
 interest to those mining in Arizona for
 1t practically and successfully solves
 he problem of treating low grade
 zinc ores We have many properties
 with zinc contents in it's ores that
 would not be treated and in fact, such
 was penalized by the smelters. The
 "Golconda" Gin that great mining coun-
 ty of Mayane) the largest zinc mine
 n the southwest ships all it's ores for
 reduction to Oklahoma. probably in
 the near future these ores will be
 treated at home.
 Great Falls.-Plans for s2,000.000
 zinc reduction plant for this city were
 announced by John D. Ryan, president
 of the Aanconda Copper Mining com pany. in the following statement. which he gave out
 Mir. Ryan's Statement
 Tt is true that the Aanaconda Cop per Mining company has decided upon the immediate construction of an cleo trolytic zinc plant which will have an utput of 70.000,OOO pounds of zine per wear and work was actively begun this morning upon it's construction. It is our purpose to push this construction IS rapidly as possible and we are con- fident that it will be completed by September 1916.
 The fact that We believe the plant can be completed by fall does not mean that it is a simple matter. It will be q very large plant, representing an in vestment here in Great Falls of more than $2000 900 and a most import ant undertaking. During the coming months until it's completion will fuTn- | ish employment for several hundred men.
 "The construction of this plant is of ! especial interest as it is the first un- 1ertakirg of it's kind in the world. IL marks the consummation of long in vestigation and the successful out | come of the research work done at the | Washoe plant at Anaconda in an en- | dea or to solve the problem of treat Ing refractory zine ores. For many years the presence of zinc in ores con l taining the precious metals has been l | curse to the miner and in the Butte | district as well as throughout the 1 western states many mines contain l ing payable quantities of gold, silver l copper and lead have been forced to I suspend operation because or the pen l atty inflicted necessarily by the smel | ters on account of the zinc content There are millions of tons of ore in ! he Butte district alone of this char | actcr. This condition led to 'he inves- 1 tieation above referred to and it is q | matter of qualification 10 all concern | ed that the problem has been success | fully solved and that a large and | profitable business can be built upon I what heretofore marked the end oi | many mining ventures.
 The enterprise had its inception ir 1 the laboratory tests made at Anacon- da After these tests had been carried l 2n successfully for a sufficient period of time a plant capable of producing 10 tons of zinc per day was built al the IVashoe smelter This plant has been successful in operation for a sui fiCiently long time to thoroughly dem onstrate the practicability of the pro ! cess It is therefore gratifying that II l addition to the satisfaction of heinz l able to add to the industries of Grea l Falls the Anaconda company is in { l position to give the mining industry in Montana the benefit of its researcl I work
