Production of iron ore in New York State 



Most of the magnetite shipments consisted of concentrates, which 

 averaged around 65 per cent iron-. Lump magnetite was suppHed 

 by the mines of Orange county and the two Mineville companies, 

 the average of this material being about 60 per cent iron. In the 

 concentration of magnetite, as practised in the Adirondacks, each 

 ton of finished product represents from a httle over i to nearly 

 3 tons of crude ore, the ratio varying with the different deposits. 

 The gross output of magnetite, as hoisted from the mines, was 

 1,294,056 long tons. The total ore hoisted from all mines was 

 1,365,064 tons. 



The list of active mining companies for the year included the 

 following in the Adirondack region : Witherbee, Sherman & Co., 

 and Port Henry Iron Ore Co., Mineville; Chateaugay Ore & Iron 

 Co., Lyon Mountain. The Cheever Iron Ore Co., Port Henry, 

 and the Benson Mines Co., Benson Mines, were inactive during the 

 year, although they contributed to the output of the preceding year.
