ID BUILD REFINERY
 AND NEW SULPHUR|C
 ACID PLANT 1T MIAMI

An event of great importance in the inning industry of Arizona is de- clared to be the forthcoming installa- tion of a great sulphuric acid plant and refinery in connection with the Inter national Shelter of Miami. The fol- lowing from the Silver Belt describes the new plants which, it is said, will employ many hundreds of men:
 The most important news in the mining field that has broken in the Miami district in several years came today with the announcement that the International Smelling company will in the near future build both a complete refinery and sulphuric acid plant ir connection with the International Shelter of Miami, treating the ores of the Inspiration Consolidated Cop per company, and the Miami Copper company. as we'll as custom ores from various sources. The far reaching importance of this announcement to the Miami district from an economic viewpoint can scarcely be over esti- mated. It will mean the construction of large plants for the refining of the copper matte that heretofore has been shipped to refineries on the eastern Seaboard; and another plant for the manufacture of sulphuric acid from the smelter fumes and from the sulphur content of the matte that has hereto fore gone to the eastern refineries. With the completion of the plants. 1t WILL mean the cIlplOYIQonI Ol nun dreds of additional workmen for their operation, with the corresponding in crease in population and growth of the district.
 The building of these new plants is in the line of modern evolution in the smelter industry. and in fact. in all industry, to fully develop the possi- bilities for the recovery and utiliza- ton of by-products in connection with the parent industry. Already large i orders for structural building steel for the new plants have been placed with l the steel foundries. The plans con- | template the refining of the copper output of the Old Dominion Copper company of Globe in the new refinery as we'll the product of the Inspira- ton and Miami Copper companies The output of sulphuric acid will be shipped to a great powder factory near Benson. Ariz., where it will be utilized in the manufacture of dyna- mite by new corporation which will 1 in the near future erect a plant al that place. c. E. Mills, formerly general manager of the Inspiration 1 powder manufacturing corporation which 1t is understood. is an associa
 tion of the copper producers of Ari
 zona. who will in the future uanufac' ture the dynamite used in their mine
 from the sulphuric acid output of thei own smeiters.
 ''F'oIlowing the erection of the In spiration Consolidated Leaching plan
 vast amounts of the by product. sul
 phuric acid. will be used for this pur
 pose. While not generally known ir
 this district. it is a matter of recorS
 that the Inspiration developed a satis
 factory teaching treatment of thei
 oxidized ores and are now compietinj
 plans for the installation of this nev
 mill. Miami Copper company Is als
 working on various teaching processe
 and win undoubtedly use the acid iron
 this new plant as a source of thei
 teaching acids.
 "The importance of this announce
 ment to the district can best be under
 stood. when 1t is stated that the pay
 rolls of the new refinery. acid an teaching. plant win equal that of producing copper mine. SO their con ' struction Is really equivalent in i'm
 portance to the district to the placin ] on a producing basis of a big new cop per property
