MANGANESE ORES. Manganese .ore, 



analysis of, 



1. — From Boularderie Island, Cape Breton, Nova Scotia. 



The sample weighed twenty-five pounds, and was in the form of 

 porous, friable lumps, varying in colour from dark brown to 

 brownish and bluish-black, with occasional patches of reddish- 

 brown. 



In order to prepare a fair average sample for analysis, the 

 whole was reduced to fine powder and then most thoroughly 

 mixed. After drying at 100° C, it was found to contain : 



Peroxide of manganese 11-04 per cent. 



Sesquioxide of iron ■. . 12-49 " 



Insoluble matter 57-76 " 



It was also found to contain a very small amount of copper — 

 possibly scarcely amounting to more than a trace,— a small 

 amount of nickel, and also some cobalt, the whole amounting to 

 (according to a rough quantitative analysis) about 0*2 to 0-3 per 

 cent., and of which the cobalt is the chief constituent.
