.019 to .022. The small amount of titanium present is interesting, 

 though it has no effect upon the metallurgical value of the ore. It 

 is due to the occurrence of small titanite crystals in the gangue. 



.While the magnetite is distributed in grains through the matrix, 

 it is readily released on crushing. The usual practice is to pass 

 the ore through coarse crushers and then through a succession of 

 rolls adjusted to give a final product of ^ inch size. 



The new mill will have a capacity of 50 tons crude ore per hour. 

 The methods to be used are based on those employed in the old mill 

 and at Mineville, with few modifications. The mill will be divided 

 into three sections, each operated independently so as to avoid a 

 general shut-down in case of accident. The first section is the crush- 

 ing section and is to be supplied with Blake and Gates crushers and 

 coarse rolls. After being broken to i inch size the ore passes into 

 a storage bin for the second section which will comprise four sets of 

 rolls giving an end product of ^4 ii^ch size. The third or separat- 

 ing section will have eight Ball & Norton double drum separators and 

 four sets of rolls for regrinding middlings and tailings. The final 

 products will be carried byxonveyor belts to the loading bins with a 

 capacity of 1000 tons. The tailings have been used for concrete 

 and other purposes with such success that an increased market for 

 them is anticipated. For the manufacture of concrete blocks they 

 are especially well adapted. They are extensively shipped for this 

 purpose to points as far distant as Scranton, Pa. 



The site of the new mill is centrally located with respect to the 

 mines now operated and possesses an additional advantage over the 

 old location of being at a considerably lower elevation, thereby 

 facilitating transportation from the different shafts. 



The concentrates from Lyon Mountain are used in making low 

 phosphorus iron. They are shipped in part to Pennsylvania fur- 

 naces and the remainder is smelted at Port Henry and Standish. 

 At the latter place a new 200 ton furnace has been erected on the 

 site formerly occupied by a charcoal plant and was blown in late 

 ing 1905. The furnace is operated by the firm of Pilling & Crane 

 under lease from the Delaware & Hudson Co. 



Mine 81. This mine is situated 4 miles southwest of Lyon Moun- 

 tain and I mile from Standish. It is a part of the properties form- 

 erly owned by the Chateaugay Ore & Iron Co., now in the hands of 

 the Delaware & Hudson Co. The mine has not been operated within 

 the last year. The deposit lies on the western slope of a low hill 

 and has a northeast-southwest strike which brings it about in line 

 with the main ore zone of Lyon Mountain. The dip is 80° south-
