To manufacture alumina from the sul-
phate, the latter is calcined with common salt,
furnishing muriatic acid gas from a burning
limekiln passed with the solution which precipi-
tates the alumina or oxide of aluminum, and
leaves a colution of bicarbonate of soda as a
by-product. So it will be seen that if an alumi-
num industry is built up in Grant county, other
chemical industries would have to follow to
use up the by-products. It would be curious
if the successful manufacture of this wonderful
metal should be inaugurated upon a large scale,
at the scene of the early experiments here re-
corded. I do not doubt for a moment but that
at some time the Gila deposit will be used to
make aluminum, the coming metal.
