SMELLING IN THE WEST.
some Of the Practises INDUCED IN ny
Utah Smelling Concerns.

Lead smelling, as prncuseu III Wv
west. saves the lead silver ana goiu
as bullion, and makes by-product
from which the copper can be reeoV-
cred. Copper smelling saves the cop
per. silver, and gold but does not re-
cover any lead that may be present.
Neither process attempts to save other
elements I'm the ore. such as zinc, aIti-
mory arsenic etc: OF the contrary
these clements are looked upon as Cd"
iectionable and II any of them are pres,
ont beyond fixed limits, ADDITIONAL
charge is made for treating the ore
Tho mine owner who wishes TO sell
his ores must yield 10 the customs es-
tablished by the smelter ana II ne
wishes TO have a fixed market for ms
ores. he must enter into contract Tor
the sale OF his output In advance the
traditions observed I'm settling for ores,
as exempllfied by certain contracts IN
the state of Utah, are indicated below.
An transactions are based on the net
ton of 1000 pounds. avoirdupois, ana
the term unit" means l per cent, or
20 pounds to each ton.
Gold.-This metal is paid for at prices
ranging from $l9 to $50 per fine ounce
(Troy), being s1.67 to 81 cents per ounce
less than the coinage value OF gold.
When the gold content of an ore is less
than certain limit, ranging at from
.02 to 10 OF an ounce per ton, no
gold is paid for at all.
Siver.-It Is customary to pay for 20
per cent of the total silver content at
the ruling price for fine silver In New
York on the date of assay. or on some
other date agreed on beforehead.
Copper--All OF the copper contained
In an ore IL not paid for by the smelt-
ers. For many years 1t has been ousto-
mary first to deduct l,3 units t26 pounds
per ton of ore) for what the producer
believes TO be smelling losses, but In
rare cases this has been modified so as
not to deduct more than 10 pounds per
ton. After making this deduction, the
remaining quantity Is paid for Mt
price which ranges from 2.5 cents to
cents per pound lower than the ruling
price In New York. This scaling down
OF the price Is usually understood by
the producer In advance, who Is led TO
believe that II offsets the cost Of trans
porting the bullion TO seaboard and
covers refining and selling costs.
Lead.-Ten per cent OF the total lead
the producer IS led to believe are
smelling losses. The remaining 30 per
cent Is paid for at prices which range
from | to go cents per pound less than
the ruling price In New York city. The
difference between the New York price
and the sitting price Is supposed by
the producer TO be for transporting the
base bullion 10 seaboard and for re-
filming and selling costs. When the lead
content OF an ore is less than units
200 pounds per ton Of ore), the GUS
tom has been to pay nothing for II, but
under exceptional contracts lead Is set
tied for when the content Is as low rs
three units go pounds per toni.
Smelling Charges. --Rates OF treat
ment vary within wide limits according
TO the locality, the characteristics OF
! the ore, and the needs Of the smelter

cases, the agreement first specifies q
base rate applying to ores carryinI

and from this base rate other rates ar,
