over period OF two months, and on a
scale of thirty to fifty tons per day by

seventeenth ounces per ton more than

nection with the less expense in les CHI
ing made the total net difference over
IS per ton.
The pamphlet concludes with sum-
mary of the comparison between the
various processes. Among the impor-
tant advantages of the process is the
ability to treat the ore in charges ten to
thirty times as great as is possible by
inauguration. Also the stock OF
chemicals in use by the process repre-
sents an outlay of not more than per
cent. of the amount represented In the
quicksilver in use in amalgama ton
mills to the same capacity, while tn,
amount of water for the Russell Pro
cess for the treatment of raw ores is
only one fifth, and in the treatment of
roasted ores only one-thirtieth as much
as for amalgamation.
