EXTRA LOW GRAEDES TREATED
 SUCCESSFULLY; CONSERVATION
 KEYNOTE IN ECONOMIC WORK

With conservation and higher eff ciency the dominating cry of the hour the world over, the copper mining or ganizations of Arizona are setting a pace that is being equaled in no other industry in the country. At the same time the copper producers of the state are of their own volition paying the largest increase in wages to their en- ployes that has come about of any in- dustry in the country. On top of this they are getting the highest result in increase, in conservation of values and in gain in output of product that is be- ing attained in any industry.
 In proof of these statements, the Ari- zona chapter of the American Mining Congress in a current report points to the fact that Arizona copper output has nearly doubled since 1914, with but one important new producer of the metal added since that time. albeit it is big one, Inspiration, with it's 12,- 1000 pounds the month at the pres- ent period. The rest of the gain has been made by producers with estab- lished mines prior to 1914.
 These producers have accomplished their gain through the expenditure of upwards of s2OO00, 900 in new construc- ton and equipment work. They are still busy with expenditures for betterments and expansion steps. One property alone will spend s75O,O 900 this year in completing higher efficiency steps which is has underway. Reference is made to Miami Copper Of course, Miami will earn this money back quickly, is earning it back now as in .stallation goes on, the ingenuity of the management providing for the re- modelling work without interrupting the operation of the plant as estab, lished. But every day they are just the same getting little additional eff ficiency and earnings by reason of the new equipment they are installing.
 Millions In New Plants
 Besides large sums which are being expended this year on new construction and equipment by the established pro- ducers with operating mines, mills and smelters, including Ray, Miami. Cop4
 
 others, with these millions being earned back almost as rapidly as put in and turned into larger employment of labor and the payment of dividends to thousands of people in Arizona and other thousands all over the country, there are other millions going into the plants of mines which are erecting urnr C ho ores, to the end of larger conservation of values and greater earnings
 Progress Is Rapid
 The arrangements of the big copper producing mines of Arizona have made wonderful advance in both the mining and metallurgical divisions in the last several years, and they are still at it. It may be that they will not accomplish as much in the next year or two as they have since 1914, but they are nevertheless going to accomplish a great deal. That much is now assured In the laboratory of no single pro- ducer operating reduction plants in the state is there idleness. From top to bottom the staffs of these organi- cations are striving for more eff ciency, more recovery of values the utilization of more material. All of them are succeeding; all are bringing forward new ideas, new applications which are receiving test in practice. Copper Queen, c. & A., Shannon, Ray, Arizona Copper, Detroit Copper. Oid Dominion, Miami, Arizona Commercial Magma, United Verde and United Verde Extension, are all at it.
 Inspiration the Last Word
 Inspiration is busy. although it has today mine and mill equipment and operating methods which are conceded to be the very height of scientific and mechanical attainment to this time The mine is daily sending more than 19,O00 tons of ore to the surface. In- deed, with the 18th and 18th units of the great mill now in commission, 19,- 800 tons of ore are being handled daily and as these new units of the mill are tuned up they will bring the ore treat ment capacity upto 10000 tons a day This is much more than the rated capacity of the mill, but it is doing the extra work easily. Twenty thousand tons of ore the day is about all they care to handle from the mine at this time, but the room has been left for more units as desired and as ex-
