Show SALT SALE LAKERS LAKER'S LEACHING PROCESS PROVES A SUCCESS Charles I. X Rader received a dispatch at they the Knutsford today saying that the I new leaching process which was introduced introduced introduced intro intro- at the Coconino copper mine inthe inthe in inthe the Buckskin mountains in southern Utah Utan two weeks ago has proved an unqualified unqualified un un- un qualified success success He at once nce handed the telegram to P. P L. L Kimberly the largest stockholder stockholder who who also alo has controlling controlling controlling con con- trolling interest in the Annie Laurie I mine mine and the two congratulated each I other The other principal stockholders I in the Coconino are Henry Ryan and M. M Dreyfus of Chicago I guess the Coconino is going to turn turnout turnout out out a a big thing thing commented Mr Rader I This process of leaching was invented invent Invent- ed by J. J Neal a mining engineer of this city he explained It is only good for copper carbonate and the Coconino has a large deposit of this form of copper copper copper cop cop- per ore and so far as discovered no copper sulphide We were in doubt t he he went on w whether nether this h new P process would O work JIe f f wa waP II J and only put In a fifty fifty- ton fifty o mill We will probably quadruple that now The nearest railroad point is Marysville the terminal of f a spur of the Rio Grande I IW W We are having constructed a steam automobile automobile automobile au au- au- au with a capacity of fifteen tons to run between the mill mm and Marysville l Probably in the near future we will start stait in Into to do our own refining at the mill mm by means of a furnace fur fur- nace nace Although we have a smelter there this kind of ore is not adapted adapt d to smeltIng smelting smelting smelt smelt- ing purposes What is this new leaching process was asked Mr Rader nader Im afraid it would take too long longto to explain it thoroughly I can however however however how how- ever give you a fair idea of af It The ore oie is ground down to a thirty mesh Itis It Itis Itis is then put into tanks of water through which is conducted sulphurous acid gas I This gas we make from the native sulphur sulphur sulphur sul sul- sul- sul which is found about miles mlles distant from the mill We e burn the sulphur sulphur sulphur sul sul- sul- sul I in a furnace and it takes up the air Well the copper in the solution takes up the sulphur from the sulphurous sulphur sulphur- ous acid gas This rills solution is passed through gh other tanks and heated to a temperature at which the copper in the compound precipitates The production of copper is going to tobe tobe tobe be a survival of the fittest Only those who can manufacture it cheaply can compete at the present prices I believe with this new leaching process we can produce copper cheaply and make a handsome profit besides beside Mr Roder will soon for th thAnnie the Annie Laurie mine |
