Metal From Mine to Market
All of these Witnesses We're qualified
to give valuable testimony on some
phase of the litigation, and some were
fortified with facts and exhibits that
would have appeared little short of
to offset testimony Offered by witness
es for plaintiffs. Two witnesses for
the Hecla and Bunker Hill. Albert
Burch and w. II. Wiley. are engineers
and biologists of national reputation.
and a partial summary of the evidence
they would have given if the case had
proceeded will be found in another col
hmn. The essential purpose of the
plaintiffs was 10 prove that the Star
mine was worthless. that it had no
commercial ore. and that such ore as
was found in the property was a COM |
of zinc and lead in form |
that rendered its successful and prof /
table treatment impossible 1t is a
matter of real regret that Hecla and
Bunker Hill were not permitted to
combat this claim by direct testimony.
for they had the most overwhelming
proof that it was false, both in form
IF expert opinion and in practical
demonstration through actual treat
nent of Star ore. This practical dem
'nstratiOn was in the form of an ex-
libit prepared by w G. Woolf. metal
urgical engineer in charge of the
Bunker Hill electrolytic plant for test
ng zinc-lead ores.
From Mine to Market. l.,
Mr. Woolfs exhibit was placed on ,
oard four or five feet square. At the Z
op was a quantity of ore as it was
AIKEN from the star mine, and beneath J
iere the results of the various pro- ;
esses of treatment until the refined t
fetal was ready for the market. First I
eneath the ore were two glass jars.
ne containing zinc concentrate and G
he other lead as separated and recov- r
red by flotatiOn. Beneath the jar of e
nc concentrates was a sheet of zinc "
bout an eighth of an inch thick as il
from the electrolytic solu- s.
on, and beside it was the residue of d
ad and silver contained in the ore. "
n the opposite side of the board there Ct
