A POPULAR STATEMENT OF PRINCIPLES
OF NEW FLOTATION PROCESS
Flotation eoncentrattion la a complete
reversal of the gravity . concentration
methods heretofore in use. In gravity
concentration the metallic purilcles sink
rapidly and more readily than the non
metalllc particles, thus In the separat
ing device or concentrator the gangue
■ lines to the top, the mineral goes to
Die bottom. The light stuff rises, the
heavy stuff sinks.
In flotation concentration the eondi
ditlons are completely reversed The
heavy (metallic) minerals rise to the
top, the light (non-metalllc) ones go to
ie bottom. Why this apparent para
dox?
Here is the explanation. If we cause
. n oil covered bubble to rise through a
pulp of crushed ore and water, the “oil
skin" bubhle will attract to itself and
carry to tho nurfacS its a cargo th»
metallic mineral particles with which
It has come In contact during Its trip
to the surface. Under certain condi
tions this action appears to be stimu
ted by the addition of a small amount
add to the pulp.
All that remains then is to furnish
ie bubbles and the oil for their skin,
he oil we can add and emulsify with
the pttlp. The air may either be blown
Into the pulp In a fine stream, or It
may be beaten into the pulp much as
the housewife beats air Into the white
of an egg, or certain gases generated
by the action of acid on the constituents
of the ore may serve as bubble-makers.
The mineral laden, oil-skin bubbles
collect on the surface and are skimmed
off or allowed to flow off, and the muss
is dried and shipped us concentrate.
From the slime or finely divided part
of the mill feed the recovery by flota
tion concentration is usually above 90
per cent. By gravity concentration a
60 per cent recovery on the same grade
of material would be excellent practice.
As to the devices or machines in use
lu flotation concentration work it may
be said that the Callow machine belongs
tc the class In which the bubbles are
formed by streamlets of compressed ulr.
! The compressed air In the ease of this
flotation machine is admitted through a
porous bottom in the chamber or vessel
through which the stream of pulp slow
lv flows.
To the second or egg heater type of
flotation machine belongs the devices
used by the Minerals Separation, IAd.,
0RTUNE8 MADE IN
TUNGSTEN FIELDS
"Randsburg and Atoliu tungsten dls
i-lctH arc like the mining camps of
1 uonecr days. Fortunes are being made
here aud a big rush and much excite
ment” stated Frank Huss of the Cali
fornia Delevolpment board, who re
turned from the district this week. He
visited the mining areas in order to
compile data for the booklet to be
issued under the auspices of the state
board in which Kern county's mineral,
oil. agricultural and manufacturing re
sources will be covered.
Secretary T. F. Burke of the board
of trade said that while in the min
ing district he met a large number of
Bakersfield people and that every one
neemed confident of making a fortune.

of the most novel scenes In mining that
one inny find anywhere, ns here plows
are being used to turn up the nuggets
of tungsten. Men follow behind the plow
teams gathering up the tungsten and
placing It In sacks as the plow uncov
ers the rich ore.
The ore is worth $3 u pound and it
does not take a very large tungsten
“spud” to be worth that much.
Many old timers are making their
last effort for a fortune in this district..
One man who had mined for 33 years
without accumulating ft competency
was met on the desert en route to Kans
burg.
He expressed determination to woo
fortune in the tungsten district.
Huss said that the old fellow has a
pack train of burros and made a typical
picture of a miner in the days of M9 —

the machines in use under the patents
of Hyde, of Janney, and of several
ethers. In this type the oil and pulp
are emulsified and at the same time
the air is supplied to the pulp by means
of paddles or beaters revolving the
a very high rate oi speed, agitating the
oll-pulp-mixture.
The third class while little used In this
country is quite common in Australia.
In this type, carbonate minerals In the
ore react the sulphuric acid In the so
lution and furnish carbonic acid gas
with which the mineral covered bubbles
arc filled. Perhaps the Jottcr-Delprat i
is the best known machine of this type.
