INCREASE IN LEAD AND
ZINC MINED IN 1912
GAINS WERE NOT GREAT, BUT
SERVE TO SHOW GREATER
DEMANDS FOR BOTH.

preliminary statment of the lead
and zinc mining industry in 1911 has
been completed by c. e. Sebenthel

tons over the 441.iS7 tons mined In
1911. This gain. compared with the

tons, indicates that stocks of domestic

Zine mining, stimulated by the high
prices for spelter which prevailed dur
throughout the country, resulting In q
large gain in recoverable zinc in ore
estimated to be approximately 55.0sG
short tons above the 345,260 tons pro-
duced by the mines in 1911. The in
crease In mine production checks very
closely with the So, 104 tons estimated
gain in smelter output. When allow
ance is made for some increase In the
productions Of zinc oxide It VIII be
seen that there has been no increase
in stock OF zinc ore at smelters, but
rather depletion
