RAPID ORE coNCENTRAToR.
rhe Trial Run at the Salt Lake
Foundry Yesterday.

By invitation HERALD reporter yes
terday attended trial run of the
Rapid" ore concentration, for which
/. Baker x Wilkes are the agents inl this
city. Invitations had been extended to
quite a number of others, as the re-
porter discovered on arriving at the Salt
Lake foundry, where the trial took
place. There were present, besides the
gentlemen who operated the concentra-
tor, couple of newspaper men,x a
number of mining men and capitalists,
among whom were Messrs. W. S.
Godbe, Henry Lawrence. W. T. Barbee,
Anthony Godbe, Judges Hunter and
Sutherland, Colonel Kaighn. Messrs. G.
D. Schell, c. NJ. Gilberson, r. Warnock,
F. NJ. Bishop, Samuel Godbe and several
more.
The concentration is small one, so
small, indeed that the query was asked
if it were merely a sample of larger one,
but one of the agents said that was the
regular size. 1t weighs but lbs pounds
and is OF very simple construction.
The test of yesterday afternoon could
hardly be said to have been thoroughly
successful one, probably on account Of
the inexperience of the gentlemen
handling it, it being of a recent inyen-
ton. 1t is of SO small capacity that
we question if it would answer where a
vast amount OF concentrating was to
be accomplished. 1t seemed to us that
one as large again, working upon the
same principle would be vastly more
preferable and successful in working up
great quantities of ore. 1t is claimed by
the gentlemen handling 1t that it has a
capacity offrom two to four tons per hour
but this was DOUBTED by practical
miners at the conclusion OF the test
of yesterday afternoon. That is, the
ore might be rushed through, as one
lot was yesterday, but the Concentrate
would not be perfect, as the tank.
stirrer and overflow were too small for
working up but certain trihing
amount at q time.
The samples of ore put through at the
trial were four boxes OF ore from the
the Silver King mine at Stockton owned
by Messrs. Godbe and Lawrence. The
first box, containing IA pounds OF 30
mesh ore was run through in twenty
four minutes, but being SO fine it as
sumed the consistency of mud while in
the hopper and consequently would
not descendinto the tank very readily
The next box was 60-mesh ore, and 10l
pounds went through in eight minutes:
a lot of 40-mesh. weighing seventy-six
pounds was finished in three minutes.
and one OF 2O-mesh. of leo pounds took
eight minutes to go through. Samples
were taken by Mr.. Bishop OF the ore
before and of the concentrates after the
operation, which will be assayed.
The Rapid" is a continuance, which
thoroughly practical men say can be
improved upon especially in the feeding,
which could be and should be regulated
according to the capacity; the betting.
also, might be bettered by having wider
rubber ones, which would not stretch
as the l4-inch leathern ones did yester-
day, and the whole machine would do
more and better work if it were con-
siderably larger
The principle upon which it works is
excellent and one that commen's itself
to practical men. The tank is circular in
shape, the bottom perforated with some
/ 800 fine holes, through which the wa
ter is forced ut any given pressure. on
the principle of a boiling spring In the
centre is rod. on which the hopper
