smelter, sometimes hundreds of miles
from the mine. When the ore goes to
a custom plant, the receiving works
samples are used as a basis for set
tlement. check sample, which
should be as nearly representative of
each carload as facilities at hand can
make 1t, should, in all cases, be taken
/ at the mine. In the case of direct
smelling ore. each carload is general
ly sent TO public sampling works,
where an automatically cut sample Is
taken and the car reblled to its des-
| tinaion This is a satisfactory pro-
cedure where convenient, but even in
this case a check sample is taken at
the mine.
When the mill is adjacent to the
mine, the removal of check sample
automatically can be accomplished
with mechanical sampler run in con-
nection with the crushing plane. When
sent to custom mill, certain amount
preferably one tenth of the weight
should be thrown aside while loading
a car and this crushed or broken with
a hammer to 2-in. Jumps, when it can
be tenth shoveled and this tenth bro

ture sample removed from the dis
carded portion. The SO pound is then
dried, ground in a coffee mill' to 30
mesh, riffied to a pound and this sam
pie pulverized. This procedure APP
piles to shipments to smelteries as
well. In the latter case the ore is
nearly always calamine and easily
broken. These samples should check
quite well with the results obtained
from the receiving works samples.
Once the ore is received at the mill,
1t must be sampled automatically as
it is unloaded or by the tenth shovel
process already described and the
moisture determined. The next pro-
blem is to secure representative sam
pies by which to control the grade of
the products and follow the losses.

samples should show results consistent
with the ore receipts. The next sam
Piles in Importance from an economical
view point are the tailings in order to
determine the losses occurring in the
milling process. A practical way to
obtain. the mill feed or crude ore sam
pies is to have an automatic sampler
cutting out a certain portion, or have
a workman periodically reserve
portion of the crushed ore. Some
sort of automatic failing sampler
should be installed, if possible, or this
sample can also be taken periodical
ly. AS to sampling the intermediate
and finished products, automatic de-
vices should be used wherever practi-

After the ore is unloaded and SAM
pied and in the storage bins, Its
course through the smelling process
begins. The ores may be smelted Sc
parately or mixed in different proper
tons beforehand. A daily sample Is
required Of each kind of crude ore
charged to the roasting kilns, or to the
spelter furnaces. according to whether
X Is sulphide Or oxide. The samples
are generally taken from each car of
ore as it is hauled to the kilns. A
pipe sampler, slotted and pointed and
closed at the bottom end, can be thrust
into the ore and gives very satisfac-
tory sample as the ore is dry and fine.
This gives a bucketful of ore which
may be riffled to pounds, dried for
mesh, divided by Jones' rifle to from
? to ounces. and pulverized. The
roasted ore is sampled in manner
similar to the crude ore. A sample
should be taken for each set of roast
ing hearths.
The roasted ore, after being con-
veyed to the mixer building, is depos-
tied in bins or mixed at once in fur
mace charges. The furnace charges
are sampled as they are being made
up, preferably with a pipe sampler Or
taken from the stream Of ore being
discharged from the bins--the samples
being placed in cans. If it is wet cal
anime ore. the cans should have screw
tops. There should be sample of
the charge for each furnace. The
samples are prepared the same as the
kiln samples. Moisture samples
should be taken in all cases on the
crude ore, since otherwise errors are
likely to be introduced through hand
ling or manipulation.
The residues that are raked out of
the retorts, if they are thrown away,
should be sampled periodically either
by taking shovelfuls out of the resi-
due car or by the pipe method If
they contain other metals and are re-
served for re-treatment, of cohrse each
car shipment must be carefully SAM
pied by the pipe method or by the
tenth or twentieth shovel. 1t Is some
times difficult to procure an average
daily sample. especially if the residues
are allowed to accumulate for more
than one day in bins beneath the spell
ter furnaces.
The spelter must be sampled period
ically by reserving a certain number
of slabs from each draw, and if a
special grade is being made, each car
must be thoroughly sampled. The
standard method set by the American
society for testing materials is to take
six slabs at random and saw each
slab completely across from the mid

Analysis of the Samples.
The analysis necessary on the SAM

pend upon the character OF the ore.
Determinations of the metals occurring
In commercial quantities must be made
also determinations shouldebe made on
enough samples to show the impurities
present affecting the metallurgical
treatment of the ore.
The samples representing shipments
to smelteries should be run for zinc
and for such other metals as are paid
for and for any impurities for which
the smelter is penalizing. The sam
Piles of shipments to custom mills must
be run for zinc and other metals and
impurities, as stated for smeltery ship
ments. In cases where the mill be-
longs to the mining company, the
samples should be run for zinc and
other valuable metals, leaving the de-
termination Of impurities to be made
on the mill-receipt samples.
AT custom mill the buyers pulp is
analysed in duplicate for zinc and
other metals being paid for, and also
for impurities on which penalty is
imposed. A pulp sample is sent to the
shipper, who analyses it for the same,
and on comparison of the shippers and

agreed upon beforehand, the umpire

his results fall between the two, it Is
taken as final; If not, the one nearest

The analysis required of the finish
ed mill products consists in determin-
ing the metals that the smelter would
pay for as flux or as recoverable and
the impurities affecting the value or

Potash It's Own Reward.

The government has offered no re-
ward to the discoverer of deposits Of
soluble potash. When it is realized
that soluble potash Is now selling in
the United States for ten times the
price asked for it before the outbreak
of the European war, and that no
more than one-twentieth of the
amount commonly used before the
war is now produced in this country
it will be seen that the government
has no need to offer reward. The
discovery of commercial amounts OF
soluble potash is it's own reward.

Mill Shipment Samples.

The sampling Of the products of the
mill for shipment, ranging in size from
~ in down to the finest pulp-that is,
from Jig concentrates to flotation
concentrates-and from dry material
up to that holding IS to 20 per cent
moisture, should be carried out in
such manner as to be reliable check
on the sampling done at the smelling
works. The usual methods for samp-
ling the fine material are by the pipe
sampler either from the car or wheel
barrow used in loading, and by dig
ging certain number of holes in the
ore after being loaded in the car and
scraping the samples up from the walls
of the holes. OF the two methods,
that of the holes appears to be the
most accurate, as ore is likely to stick
in the pipe and not give an even Sec
ton of the carload After the sample
is taken from the car, If finer than
go mesh, it is quartered to about 5
pound if coarser, about so pounds is
taken and reduced in mesh by grind
ing, then in quantity by quartering.
A moisture sample consisting of the
regular sample for analysis or an extra
portion should be weighed out and
dried. This sample usually amounts
to pounds and is weighed on special
moisture scales, supplied with double
beam to read percentage direct. The
sample is further prepared for analy-
sis by methods already described
The next stage in the sampling pro-
cess is when the ore arrives at the
smeltery. 1t may come in the form Of
lump calamine, lump sulphide or any
of the various mill products, both CAL
anime and sulphide. (The term cal
anime is used here to designate any
of the oxidized zinc ores.) The ore
may be imported from Australia, Sar-
DINA, China. and various other parts
of the globe, or shipped from different
local points 1t is customary for the
shippers to have representative on
the ground to inspect, in their inter-
ests, the shelters sampling methods,
and, in case of imported ore, for the
government also to have a man sta.
toned at the works to take the nee
essary samples to enable proper duty
to be exacted.
At few Of the zinc smelteries there
are proper facilities for sampling lump
ore automatically or at least mechan-
| ically, but at most 1t is rather a slow
and unsatisfactory process to procure
a representative sample. Where
neither facility is provided, the lump
ore must be sampled by taking orde-
tenth, or one twentieth Of car and
breaking the Jumps to 2-in. size either
by crusher or hammer; taking one
tenth of this portion and again break
ing the Jumps to " -in.; then mixing
and quartering the ore to so pounds,
taking out pound moisture sample
and grinding, riffling and pulveriz-
ing. When the government requires
samples, the final sample for pulveriz-
ling should weigh about " pounds;
the sample Is divided into six portions
