NeiI. the resident representative of the
Taylor & Brunton Sampling Works
company. delivered an interesting and
instructive address on the subject of
! The Advanced Methods of COncen-
tration," and although the gentleman
| did not expect to be called upon for
his talk until later in the session, and
was without his notes and samples of
| concentrates with which to illustrate
/ his remarks, he spoke in an easy and
/ pleasing manner and made himself cas-
/ lily understood even to the Gninitiated
in mining parlance.
In his Introductory remarks Mr..
Neil stated that the subject was one
which affects the miner when his ship
ping ore has become exhausted and he
has TO fall back on low grade milling
ore and dump waste; a condition. fortu-
Eately. that has not as yet confronted
/ the Utah miner and mine owner, al
/ though the process of concentration is
l beginning to win its way in several of
! the mining camps of the state and is
4 being employed in a number Of in
stances 70 advantage and profit, sew
4 eral hrst-class plants employing this
system being IN operation at some of
/ the leading mines in several of our
I leading districts.
/ Concentration" Mr.. Neil went on to
! say, lis the dressing of ore, two meth
! odS being employed in the recovery Of
I the precious metals and the elimila-
ton of the waste and gangue-the wet
and the dry, the former being as old
as the hills. while the latter. to a GER
tain extent. is a new candidate for pub
| lie favor but with such merit that it
is rapidly winning its way in mining
circles in tbs western country where
the metallic values are 50 closely blend
ed and fixed with its gargue or matrix
that III ir separation is difficult or next
| to impossible. which is so often the
case with pyTitic, zine ard iron ores.'
MONEY FROM ORES
In Germany, where concentration is
largely in vogue. the art OF mctailurgy
is called the science of extracting met
ais from ores. bet in this country we
term il the science OF extracting money
from ores"

PYRITtC ROASTING.
This process. Ar. NELL stated. might
be tcIEild pSIiJlc roasting, aid con-
sisted OF the roasting CT ores carrying
ryrites associated with The precious
metals, and iron and zinc ores. the min
oTal being roaSted before being
crushed, the process eliminating the
sulphur. the escape of which in itself
furnished fuel for the successful con-
tinuance of the operation, while, under
the conditions resulting. the iron be-
came EagnetZed. After roasting to a
certain extent and before the point of
smelling IS reached. the ore or matte
is crushed. the prodUct passing over
E.agnets. which separated The iron
from the ore. leaving a concentrate that
could be easily handled and which was

saving or recovery of the precious met

COMBINATION PROCESS.
Reference was also made to the COM
binGtion process. which made its first
debut at the Drum -ummOn mine and
mill at Mary Mont, and which
has since been found 10 be so service !
