 Treatment Of SuLphide Ores

"Ut tuSfe dIS enough Simllarities and the process is so succession wherever used. that. the proposition Is taken largely out of the experi- mental stage.
 With the acquisition of the Ain Consolidated by New Cornelia. mn. derground mining in the camp re- eelved its start and impetus. A three. compartment shaft was sunk 25e feet. when activity began in earnest = not on very large scale, to he sure, but new kind of mining. and quite a spreading out. There are both charms and possibilities in un- derground mining not attached to the steam shovel pit
 Not on large scale we said. Wei one who visits the mine for the first time in quite a while will see {. da. cided change for the better. thera being an air not only of growth achievement; ore bodies eSplo,ed proven and added to the blue-print but there is moTe-the present is larger; the prospects are brishter. the future is nearer. New Corpeha has increased it's proven ore bo6ias by the purchase from over 40 OOO OOO tons to over 6O.OOO. 900 tons - and more than that, which will all come out in due season. New Cor. nelia never being content to meralv make good its promise.
 On the completion of the shaft sinking to 2SG feet. the force waS increased. A change room for inc men and q blacksmith shop there. fore sprung up.

 Then began development in earnest on the 250. Two obbiects were in view - to block out the high grade ore for shipment, and to de. Veiop the low grade ore for the ex- south, lies the high grade; to the west the ore of lower grade; the showing of beth are fully up to expee. tatiOnS.
 When the levels are run. up. raises are drilled; of these there are three. One is completed. a connec- tlon having been made a few days ago into the east Glory Hole: this IS one and One-half compartment tSX1 feetl. The other two. to the west and to the southwest. are two compartments each. or 5xlO feet.
 The ore Will go down the inclin- ed rails into the waiting cars. and thence be trammed to the cage. there to be lifted to the surface. It Will then be dumped into railroad cars for shipment to the shelter tin case Of the rich sulphides) or for transportation to the flotation plant tin the case of the sulphides of low CT gradel.

 Shipments to the C. SS A. shelter at Douglas have been going forward at the rate Of about 250 tons a day. But accomplishments completed and soon 10 he finished will permit New Cornelia to increase within 80 days or such a matter, to 500 tons daily.
 Three shifts are at work here, requiring 8 sorce at present of about i50 men.
 At the steam shovel mine. two shifts are being worked, a force or about 200 men being employed in this department.
 Easy for us is the verdict of departmental heads. Such efficiency has been reached by careful plan ming and checker workouts; when they want more ore, let 'em tell us we'll furnish it.
 And last months fi~ures, with a production of better than 4.20O,0O pounds, speak for themselves. New COrneiia is getting down to business. The promise has already been reach ed - and then some yet nobody says, impossible to do better; the and heads will never be. satisfied unless continually improv- ing everywhere possible.
 The figures for cement copper were rather high last month, but this is due merely to the cleanup The general average for year has so far been found to be about 25 per cent of the total: or, to be more nearly exact, SS,0OO pounds daily, out of total of 1SO.OOO to 10000 pounds"
 Editorially, the News continues: New Cornelia copper is the one best copper belt in Arizona. This statement is Justified, first, by the proven ore bodies; and, second. by low cost of production.
 The known ore bodies total over 60, 100000 tons of low-grade, most of which can be mined by the steam shovel process These figures do not include the ores of high grade oc- curing here and there in, the low grade ore, sCme of the values of which will be recovered; nor the ores comprising the secondary en- richment below the steam-shovel area, which the company has never figured in as an asset
 The low production cost is made possible by the rapid, labor-saving steam-shovel process, preceded by almost no stripping necessary: favorable grade (gravity) from mine to mill distance of only one mile; and by the cheapness and of the teaching pro- cess, which requires but little labor and leaves but little waste. The teaching plant almost operates it. self, in fact the entire system comes as nearly to being machine-done au- as it is possible to con.
