Analyses* of Pennsylvania Pipe, and Pennington Ore.

January 5th, 1871. 

 Dear Sir: — Herewith I beg to forward you the results of my analysis 

 of the two samples of ore, marked, respectively, "Pipe Ore " and "Pen- 

 nington Bank." 



The whole of the samples were intimately pulverized together in each 

 case ; they contain 



PIPE ORE. PENNINGTON BANK. 



Silica 10.84 5.42 



Peroxide of Iron 73.18 79.05 



Protoxide of Iron .75 



Aluminia. 2.51 1.29 



Oxide of Manganese traces. .11 



Carbonate of Lime 20 



Carbonate of Magnesia 1.30 Magnesia. .11 



Phosphoric Acid 17 .04 



■ Combined Water 9.09 10.57 



Moisture 1.81 3.55 



Sulphur 05 



99.80 100.14 



Metallic Iron ... 51.81 55.34 



" " exclusive of Water ,.58.25 64.35 



Both these samples are rich iron ores, sample "Pennington Bank" 

 being nearly pure brown hematite. The pipe ore is a harder ore than 

 " Pennington Bank " ore. 



I consider both samples of ore adapted for the manufacture of Besse- 

 Hner Pig. 



Believe me to remain, yours, very faithfully, 



Edw^ard Riley, F. C. S., 



Metallurgist, Analytical and Consultiny Chemist.
