THE MINES OF ARIZONA

section has a crushing and sampling department. In the sampling de- partment the ore will be cut four times by Snyder Automatic Samplers, and a sample weighing 1.6 or 32 pounds, as desired. per ton of ore passing through, will be obtained. The plant is flexible and ore may be crushed and screened and discharged at any desired size.
 Bedding and Conveyor System From the sampling and crushing plant the fine material will pass to the fine beds and coarse material to the coarse beds. The bedding scheme is practically a duplicate of the Cana nea system. Three beds for coarse and three beds for fine ore are pro vided, each having a capacity of 900 tons. A bed of coke having a capacity of 5000 tons is also pro Vided. The coke will be dumped from the cars into the coke receiving bins and from there it will be conveyed directly to the blast furnace charge bins or coke storage bed, Reclaimers similar to tthe Cananea. reelaiming machines will reclaim the material from the fine and coarse beds The coarse ore and coke will be conveyed up an incline to the ore and coke charge bins directly. oyer the blast furnace charge floor. The fine ore will be conveyed up a similar incline to the roaster plant.
 Roaster Plant
 The roast plant contains twelve 21 F+ e having a capacity of approximately SC tons of fine ore per day. The roast CT plant has a tile and steel dust chamber 50 it. X 40 1t. 70 it. high, equipped with baffles and wires. The roof of this chamber and the blast furnace dust chamber is of copper This dust chamber discharges into brick lined steel chimney. 20 1t. in side diameter by 279 it. high.
 Main Building
 The main smeltery building is 222 fl. 460 it. in plan, and it will con- tain two blast furnaces, four re- verberatory furnaces. six converters, the copper casting department. etc.
 Blast Furnace Department
 Two 48 in. 40 ft./ blast furnaces are provided. Ore and coke will be discharged directly from the bin just over the charge floor into charge cars which will rest upon platform scales. and the amount of coke and ore for each charge will be propelled from the scales to tthe charge doors of the furnace by an electric motor. A steel dust chamber 60 1t. 1SO 1t. X 70 1t. high having suitable baffles and wires is installed. The converter gases will also pass through this  Der and also the gases from the reverberatory boilers will pass into a brick lined steel chimney 25 feet inside diameter by 305 feet high.
 Reverberatory Department
 In the reverberatory department. four reverberatory furnaces 19 1t. 100 1t are installed, and the founda- tion and building for a fifth furnace are in place. Each furnace is equip ped with two TIP h. D. Stirling boil CTS, making a total of eight boilers. With the boilers a suitable water measuring, heating and pumping sys tenn is being installed. The furnace are charged directly from the calcine cars running on track overhead Matte will be tapped into 20-ton pots and transferred by cranes to the converters. The slag will be skinned directly into 25-ton pots running on tracks underneath and just in front of tthe sllimming end of the fur naces.
 Converter Department
 The main converter aisle is 5 feet wide, and two 40-ton electric travel ing cranes of the most modern con- struction are installed Stands for six Great Falls type cOnverters are provided. Two straight line casting machines are being installed and a considerable amount of auxiliary equipment. The converter slag will be poured directly into the reverber atOry furnaces.
 Water and Oil System
 A new water tank for the blast furnace water jacket supply is being installed, one for the power house condenser water, the other for the re- verberatory fuel supply. It is believed that the plant will be ] put in operation within the time 1 estimated August first 1913 l
