Reduction OT Ores.

Reduction Of Ores.
 We have frequently referred 70 tin
 nrocess of lixiyiation in the reduction Iof rebellIous ores, from its seeming
 value and adaptability to Arizon'
 mining. 4 very strong point in it flavor Is that throughout the mining regions of Mexico, where any proces.
 which would add cheapness and sim
 plicity to an average or increased amount of metal produced, would bo the most desirable process, it has been
 extensively adopted.
 In THE CITIZEN of October 23, we
 gave much space and full details of this process, and have since referred to it. It now seems to be g g-tting a hold on public attention and in the San Francisco Bulletin of December 23, are some notes on the subject from
 Mr. E. B. Smith, for many years Q resident of Mexico and the introducer of the ixiviation process into Mexi- can mining who now resides at 439 Bush street, San Francisco.
 Speaking of the foregoing process, Mr. Smith, in the Bulletin, says:
 Having introduced the process in Mexico, and having originated all the improvements that have been made in the mechanical appliances connected. herewith at my hacienda La Agu- ia, situated on the Rio Yaqui, Sono- "a, Mexico, and having ill the seven years since its introduction treated successfully every conceivable com bi- nation of rebellious ores, I feel war ranted in saying that for all silver ores that require desulphurizing or. before treatment, there IS no known process that has so many practical advantages as whatis known IS the Sonora process " of chiori- nation and lixiyiGtion.
 The advantages are briefly these lst. 4 saving of at least 33 per cent, n cost of construction of reduction works. No machinery being required sxcept stamps for crashing the ore, with he necessary power for driving the stamps, and the necessary tauks, which cost much less than any ap- 1aratus for amalgamation with quick ilver. 2d. h the working expenses ,nly about one-third the power is equired and consequently much less uel is used, As much coarser screens Ire used, about oue-third more ore Is rushed to the stamphead. Lime and ulphur used. cost less than quicksilver ost. The wear and repairs of ma !, hinery Is less by one-half than ill (
 mill where pans or barrels are syd. Sd. And the most important dyantage Is that in working the ebellious ores of Mexico the percent ge of silver extracted was twenty I CT cent. larger than when treated nth quicksilver, and the bullion is rom 300 to 9JO fine. In a word, the Iccess has been so complete, that its SC has extended to all tine mllls in onora and to many in Sinaloa, Du- lngo and Lower California. ! The process Is exceedingly simple | nd at the labor connected with it ! m be performed by the commonest A .borers. The only skill required is '
 the roasting of the ores, which m all be under the direction of one an, and any intelligent mill man -n learn the whole process in few eeks.
 l do not think this process has ever zen tried in California or Nevada It l am confident that there are any localities both here and in Ne .da and Arizona where it could be troduced with very great advantage. This mode of treatment is no mere cory or experiment. It has been in tual working for some years, and
 Sonora has superseded all other 1des of working ore. It is covered
 no patent, and there Is no secresv humbug about it. | shall be happy to give any fur 3r information to any who may u on or write me.
