The exhibit of nickel ore by the Canadian Copper Co. is 
very extensive and includes masses of copper and nickel ore 
weighing respectively three, four and six tons. Samples of 
the selected copper and nickel ore are displayed on one side. 
Numerous photographs line the walls of the center pillar; 
specimens of the graded ore. as well as of the finished products, 
alloys and pure metal are seen in the show cases. The whole 
subject of the treatment of the copper-nickel pyrrhotite in 
the diorite gangue, from its mechanical sorting to its treat- 
ment in the roast pile and its extraction as matte in Besse- 
mer converters and its transformation into an alloy of about 
equal parts of copper and nickel, or the elimination of the 
copper and the resulting nickel of nearly 99$ purity, is one 
of the most interesting in the department of Mines and Min- 
ing. 
The entire exhibit, as to arrangement, labeling and mate- 
rial, is one of which its managers have every reason to feel 
proud.
