USEFUL METALS 



187 



scrap tin, type metal, babbitt, friction -Ix-ariii^ metals, tin cans, 

 etc., has boon carried on by the Vulcan Metal Refining ( 'oinpany 

 of Sewaren, New Jersey. The method of extraction is by elec- 

 trolysis. Fifteen per cent, of tin is said to be recovered from t In- 

 old scrap tinware at a very low expense. The residue of 

 is compressed into blocks by hydraulic pressure and sold to 

 the open-hearth steel manufacturers for the same price as scrap 

 tin (therefore the source of the tinware costs nothing save 

 transportation). 



Several companies have been organized in the United States 

 for the purpose of exploiting tin deposits and the extraction 

 of the metal from the ores obtained. The Niagara Tin Smelt- 

 ing Company, located at Niagara Falls, N. Y., and the North 

 American Smelting Company of North Dakota. These compa- 

 nies have exploited the stream deposits in the Dakota tin belt 

 and sought to enter actively into the production of tin. The 

 American Tin Mining Company has produced a few tons of 

 placer tin from Buck Creek in the Seward Peninsula. The 

 Bartels Tin Mining Company in 1903 at Tin City, 5 miles south- 

 east of Cape Prince of Wales, sunk several shafts and drove many 

 drifts in their quest for tin, but the results were meager. The 

 United States-Alaska Tin Mining Company has continued pros- 

 pecting by tunnelling to a vein in Cape Mountain, but no pro- 

 duction has resulted from their labors. The Tinton Company, 

 South Dakota, has remodeled its mill and expects not only to 

 mine tin but reduce the ores to the elemental state. 



With an annual importation of tin valued at approximately 

 $25,000,000 it appears as though the active exploitation of the 

 tin placers and lodes deposits in the possible tin-bearing belts of 

 the Carolinas, the Black Hills, and Alaska should be reasonably 

 rewarded for the expenditure of time and money.
