NATURAL RESOURCES OF QUEBEC 
PRINCIPAL MINERALS 
Aluminium.—Although the province of Quebec does not produce 
ores of aluminium such as bauxite and cryolite, the development of large 
water powers on the St. Maurice and Saguenay rivers has attracted several 
slectro-metallurgical industries which require abundant and cheap power, 
among which prominently figures aluminium. 
The importance of cheap power for the reduction of alumina to metal- 
lic aluminium may be realized from the fact that one horsepower-year 
is required to produce 500 pounds of the metal The water-powers of the 
province of Quebec constitute one of its chief natural resources. The 
available power resources in the province at the ordinary minimum flow 
is estimated at 8,459,000 horse power and of this only about 2.055,000 
aorse-power has been developed. 
The Northern Aluminium Company, which is allied to the Aluminum 
Company of America, operates a reduction plant at Shawinigan Falls, 
having an output capacity of 20,000,000 pounds of aluminium a year. 
At their large works at Shawinigan the metal is manufactured into ingots, 
allovs, rod and wire. 
In the Saguenay-Lake St. John region, at Arvida, near Chicoutimi, 
the Aluminum Company of Canada, has recently completed the first 
anit of a plant for the reduction of aluminium. The power used at the 
Arvida works is at present supplied bv the Duke-Price power plant at
