SASCO SHELTER AND POWER
 PLANT AT SASCO, ARIZONA
SF Shaw, Mining Engineer, Gives Description of Reduction Works of the imperial Copper Company in the Mining World-Seven Hundred Tons of Ore Sneted Daily
 and Output is One Million Pounds Per Month

The smelter town of Sasco. with aboat 300 inhabitants. is situated on the Arizona Southern railroad, about elsht miles from Red Rock, Arizona. TWO years ago the erection of this sMelter was begun chiefly for hand Ing the ores of the Imperial Copper Co, The first unit consisted of a furnace of 350-tons capacity. which within one year was found inadequate TOT handling the mine output. and q second furnace was erected and blown in about December l, 1908.
 The ore cars of 100. .0O0 10. caDacitv are hauled from the mines by loco motive over the ore bins and dumped. There are IS of these ore bins having. without shoveling, a capacity of TO- 0a0 tons Four of these bins are at present used for coke, but will not be needed for this purpose after the coke bins have been erected. Each bin has six chutes, three on each side, and spaced according to the length of the charge cars. These chutes are
 provided with Fairbanks hopper scales, Saseo pattern, of 2500-lb. capac- ity, and are movable on a two-raiI ] track, making 1t unnecessary to pro vide each chute with scales. The charge train consist of eight cars drawn by a 3-ton electric locomotive and is run beneath the scales and the charge dropped from the hopper; the doors are operated by a hand lever but will later be opened by a com pressed air cylinder. The train with it's charge of nine tons is hauled tC ! the feed floor and dumped directly into the furnaces.
 The furnace at tuyere level are A ] in. by 16 it., and extend F it. iron | tuyere level to feed floor About 40( ! gal. of water per minute flows through ! the jackets of the two furnaces, dis | charging into a tank, from which 1t is rlmped by two 5-in single stage cen l trifugal pumps, each direct connected
 to a 15-hp. motor. to a cooling tower ! From the tower the water flows b. | gravity to the jackets. The blast al ! 24 to 2S in. pressure enters tine fur mace through 22 tuyeres there beins | i6 on each side.
 There are three settlers, each 1: | by it. The siag overflows contin
 uousIy from the settlers to lotion slal pots, which are hauled by a 14-tol 1 Davenport steam locomotive. To in crease the fall of the dumping ground the track was run with a 2 1-2 per cen
 grade.
 The gases are conveyed through S4 1 in. inverted V-pipes into the 15 by 2 by 120ft. brick dust chamber. and arr then discharged through a steel stacl
 12.5 by 175 1t high. The Hue dus
 is drawn from hoppers into cars
 which for the present are hoisted by ;
 small engine to a paddle-mixer, ant
 mixed with the necessary amount O
 moisture, and wheeled by barrows tC
 the cnarge cars. This method is tt
 be changed as soon as the best meth | cd is worked out.
 The ladies containing the matt' ] from the settlers are handled by a 50
 ton electric travelling crane; thi!
 crane, also handles the converters
 The converters are of the horizonta
 barrel type S4 in. in diameter by 12i it.. and when provided with a frest 1 lining contain about five tons o matte. The mate when first delivered | to the converter contains about 45 De
