HOW ORE IS SAMPLED.
Process Employed at Smelters
for Determining Values.
A brief description of how ores tiro
sampled at smeltera lu order to arrive
lit their viiliien, limy prove of intreoHt
to the general reader. In purchasing
ore shipments it Ih necessary to arrive
nt Home basis of itettlemont between
the Hmelter people and the ownerH.
ThlH is done by mcatiH of a process
known hh sampling, t object of
which Ih to obtain averago samples
representing an eiuitablo value of
the ore. The Sampler Hmelter com
pany employs the name method which
itHiially obtains among all HtneltiiiK
companion.
Here the ore Ih II rut crushed in u
20x10 lllake criiHher. It Ih then
elevated sixty feet aud spouted into
a Snyder sampler which cuIh out
twenty per cent. TIiIh Ih done by
means of puhhIiik the crushed ore
against a revolving oval dim) with
apporhireH in it ho arranged that
twenty per cent of the ore pannes
through into spouts which convey it
to a lllake criiHher where it Ih ntlll
flirt tier reduced. The ore next piiHHeH
by nieaiiH of HpoutH into a second
sampler like the II rut in pattern where
ten per cent Ih cut out, the reject
panning into the reject eleavtor iih
above. After leaving the second
Hiimpler the ore passes through a net
of rollH grinding It down nt 111 liner
anil preparing it for a third aud
Htuuller Hiimpler which cutH out au
additional ten per cent, and piihhch
the Hiimple on to a hiiiiiII (Jatcn
erunher which still further rcduecH
it. TIiIh Ih the liiHt ntep in the
process. i'Voin the (late crusher
the Hiimple kdch to the sampling lloor,
where it may receive any farther
preparatloiiH needed if not ground
to a Hiilllcleut lluoucss, and quartered
iih desired.
When thin process of averaging and
reducing the ore Iiiih been completed,
the Mimple, after It has been quartered
down iih Hue iih desired, Ih then ready
for the laboratory where it Ih iiHHiiyed
and Hh value determined.
MONEY IN LOV GRADE ORE.
Governor Brady, of Alatka, Writes of the
Treadwell In Hit Anaual Report.
The average person iiHHociatcH
almoHt any gold mining proponltion
with miirveloiiH finds and Hpeedy
wealth, without stopping to coiiHider
that many of the big paying mines of
the country produce low grade or en
and are not only steady dividend
payei-H through a long period of
yearn, but employ large forccH of
men thereby making them good
distributor of wealth from thin
point of view. Speaking of the
Treadwell mine in Alaska, a low
grade proposition, Coventor llrady,
in his annual report, says:
"The Treadwell mine getn better
iih It gocH deeper. The more we can
Increase such plants ou low grade
ores the letter It is for the general
communities. .Most of the product
Ih paid out for labor and material.
The total yield of the Alaska .Mexi
can mine to December, HUM, Ih
given iih 'J,:iH!,iioV.7. Out of
this sum only i?lt!5,:tSl wan paid
at) dividends. Low grade properties
of thin kind are about iih good
distributors of earning iih are
sawmills. The net prollt for each
ton of ore treated lu the Mexican
for 1001 wan a little less than 14
cento. The yield per ton was about
81.00, and the operating coat per
ton was 81.70. This in a wonderful
showing in economical and efficient
mining and milling, and it in some
thing that every Alaskan feels proud
of."

qf Robbins & Robbius was at the
Uolcouda Friday for the purpoHO of
Hampling a shipment of ore which 1b
