Warren District Mines

2 be utilized in the new one as is Prac. ticable. The old ore bins win be enl- ployed and will be equipped with suit able chutes for feeding the ore to ! hoppers, from which the ore will go [ 10 conveyor feeders large belts hold | ing buckets that will convey the ore ! up a 30 Ter cent incline. There VIII | be a conveyor belt on each side of ' this row Of ore bins, and the ore will l be lifted to the sampling and crush ] ing plants.
 The coke receiving bins will utilize ! the present storage trestle as an ap- proach. and for the coke bins proper new steel frames will be put up which will be lined with steel that will be taken from the present flue and dust chambers. These bins will each have 8 capacity of $50 tons.
 Lively Crushing Plant. In the crushing and sampling de- partment loo tons per hour of ore. If ell is screened down fine for roasting. can be. handled in one hour. or. if large pieces are screened out for blast furnaces, 200 tons per hour can be handled The building for this de- partment will be Of steel and concrete throughout. will be f0xS4 feet by five stories high.
 The Mill.
 The min will be in two sections, and one portion may be run independ. ently of the other if so desired. Each will have crushing and sampling de- partmept. The ore will be cut four dmes by automatic samples, and all the ore In bins will pass through the sampling department. Ore can be sent to bins without going through the sam pier if desired.
 From the sampling and crushing department the ore will pass directly to either the coarse ore beds, or the fine ore beds, being carried by belt conyeyors.
 The Bedding System.
 The bedding system to be employed here. is similar to that ct Greene Can anea, mines. Sonora, Mexico. which Iron Ore described at length in a former issue. It has proved a splendid success al Greene, is 10 be adopted by w A Clark in his new smelteT, and we understand pr Riclletts, local manager Of the Greene Cananea com pany's operations, has recommended it for the Arizona Copper company. which is 10 erect a twO-million-dollar smelter under direction Of Dr. Rick, etts, the company's consulting engin- eer. who returned from Scotland last week, where he attended a meeting that authorized this outlay.
 In these immense beds the material is deposited and mixed ready for charging into the furnace. It is re. claimed from the beds by power shOy- elers, cutting slices that are auto matically pushed upon conveyor belts to be delivered wherever desired.
 Has Big Capacity.
 Calumet & Arizona will have seven -af- 4A9Se- la4S4 11llEz -k2 used for coarse ores each with . ca- pacity Of 1000 tons, and three for fines each with a capacity of 10000 . tons, so that 34,00O tons can be bedded here.
 Of course it win be understood that these beds will not be 6lled to their capacity as some of them will con stantly be ill process of bedding. or mixing.
 Will Prove Great Saving.
 These beds will prove of great ad- vantage to the company over the old system where only a small tonnage was handled. There was only a very small storing possible, not more than enough to last a couple of days, hard ly that, and when changes had 10 be made in mixtures, as different grades came to the furnace, it made much extra labor and often no little confus- ion and delay 10 get mixes right. There was thus always a conflict be. tween the mine and smelter ends cf the industry 10 observe proper eqdi- librium.
 With the bedding system thousands of tons or ore can be prepared ahead of the daily needs of the shelter, the material can be handled in a wholesale rather than in a retail way, ana a more even charge can be ob- tained as well as permitting the talk ing of full advantage Of ore changes The ores, the reader will see, have all been sampled and have been con yeyed 10 these great beds and mixed with the elements needed for thi- proper smelling.
 Thus these beds constitute great value in permitting correct mixtures and in getting them combined in quantities from which they can be drawn ss rapidly as they can be | treated.
 Coke to Be Handled We'll. There will be a bed for coke that will contain 3,500 tons. The coke [ will be delivered from railway cars i to receiving bins and thence to blast I furnaces or to coke storage bed. The ! coke from the storage bed will be I reclaimed by shoveling or wheeling ! to conveyor belt feeder. Coarse ore | and coke charge bins which will be To l cated directly over blast furnace | charge floor. The fine ores will be l conveyed up similar incline to roast ing plant.
