Mining Man Gives Brief Statement oi Process of Treating Arsenical Ores Small Outlay of Capital Big Returns District Offers Good Field Abund ance of This Mineral Here, An Industry which will probably riHMllVD llttolllioll ill tllllO t() C(lllll) in tho Humpler district, and which olFVrs 11 prolltnlilii Hold for invest tnoiit 1h tho prodiiiinii of iirxonclc.

Great Progress Made in Cyanlding Opera tions With Low Grade Propositions. The greatest stride which hare been made in tho gold milling indus try of late years hare been in connec tion with low grade propositions. Tho accomplishments in thin connec tion aru simply remarkable. Chietly through the aid of cyanide, vast do PohIIh of low-grade ore have been rendered prolltably marketable, where otherwise they would have been viiIiiIchh. Not all classes of low- which II will 1 111 v to reduce in cornice- grade ore can be no handled and tho tiou with the ordinary smelting ' operation dependH iiIho upon tho eon proccMM. An arsenic plant Involves dillons under which the depoHltH oo the nut lay of hiiiiiII capital and can , Mir. Nor Ih it only to cyanide that the lie operated in conjunction with any lw-Kiiido mining Industry owch its reduclioii workH where the ores ' success. There are other factor, Hinelted carrv nrsoiilciil values. It 1 chief among which Ih tho scientific Ih not probable, however, that the present smelling company conteiu pliitos an immediate move 'In IIiIh direcllon, although it Ik a matter which, it Ih Mated, Ih likely to come under future advisement. A well known milling man Iiiih IIiIh to nay relative to the subject: "The production of arsenic. Ih an ItidiiHtry which Iiiih received but little attention In IIiIh country, although not for the lack of adequate condltloiiH and not hccaiiHo 11 doen not oiror a prolllable Held for Investment. Huielt 1 us; cniiipaii,los In the past have In fact passed the matter up without any serious consideration. In the Sumpter district there in plenty of ore carrying arsenclal values, and since the process of reduction Ih simple and involves but hiiiiiII expense operated in connection with a smelt ing plant, there Ih no reason why the present smelter people should not, In time, Install such a plant. Arsenic Ih an article of commerce used largely In the manufacture of glass paKir, calico printing and also hi medicine. It Ih extracted from the ores by a process known as sublimation, which consists of allow ing the arsenical vapors from the smelter to cool in brick chambers where the metal Ih precipitated in the form of a grayish powder. Thin powder Ih thou roast ml and the filings driven Into a separate set of chambers where the arsenic attain sublimes In an almost chemically pure form. These chambers till several times a year, deluding upon the character of the ore and the capacity of the plant. The arsenic collects In- a grayish crystalline form practically tilling the openings. It in then taken out, pulverized and Ih ready for shipment. "The plant Itself Ih very simple, tho chamlier tioliig usually construct ed of brick, having an aperture something like Ox (J feet with doom at Intervals for taking out the arsenic, and coniiiiuiilratliiK with a stack for carry Iiik "If tho vapors. Tho anon leal fumes from tho smelter itra usually conducted underground to tho Unit set of chambers where th metal is deposited in tho crude form. Ouly three or four mou work ing on shifts are required to keep the plant gong. " Thorn Is at present only one arsenic plant in the United States, ami this is run lu oouuootlou with tho Puget and economic systems of operation which have been devisd. The matter of the cyiiuidlng oper ation Ih very interesting. Prof. Merrill, the cyanide authority, re cently said: "The average value of the sand treated In 1111)2 was 81.05 per ton. The average cost of cyan ide treatment was .115:1 cent per ton. The average percentage recovered in bullion by tho treatment during tho past six months wiih 7-1.7. The slimes carry an assay value ranging from 80 cents to 81.10 per ton. "The maximum monthly tonnage of this plant wiih attained lu October, 1 !)()-, when 1(),'2:I0 tons, or 121)8 tons per day, were treated. Tills gives to tho lloinestako company tho Ingest sand treatment cyanide plant In the world, th uext largest being I lielivee, that of the Simmer and Jack, in South Africa." The Hoinestake company lms cer tainly accomplished wonders In the matter of mining and treating low-grade ore. Nor Iiiih tho com pany followed a seltlsh or niggardly policy. From time to timo tho world is told of what Ih being done and how it Ih being done. Journal and Intvesor. F. O. BUCKNUM Examiner of Mines, Lamia Htid Investments in Oregon, Washington or Idaho.
