The diamond drill. (Crystal Falls, Iron County, Mich.) 1887-1996, 1908-10-24

the oxygen Is 1. 400 degrees Fahrenheit ,
The temperature necessary to fix iron
sponge So il will not reoxenize is 200
degrees F. The oxygen is taken ont
by the hydrogen and the hydro-carbon
gases. This constitutes Of the first step.
The second step consists in removing
this mass of de-oxygenized ore In
mass of about one ton TO Lauth ball
ing furnace. The temperature in this
furnace is raised TO 3. 200 degrees f
welding heat. 1t Is then removed
to what is known in rolling mill prac-
tice as the hydraulic squeezer, which
saueezes ont the remaining Stag and
earthly constituents This Stag will
contain. about eighteen per cent OF iron
In the form OF silicate Of iron. As
/ he value Of the iron unit in the low
grade ores controlled by Mr.. Jones are
worth only about one cent a unit this
loss is not material one.
This ball is now squeezed into
bloom and rolled into product which
is called muck bar. This muck bar
can be cut and piled and rolled into the
ordinary bar iron FOR can be remelted
in an open hearth furnace.
AS the second step Of the process Is
Ian oxygenizing one, the small sulphur
content which may come into the
sponge, can be eliminated in this fur
mace. In all cases the PHOSPHORUS
content forms combination with the
hydrogen and passes Oft with the gases.
Mir. Jones is certain that, with his
process one ton OF bituminous coal
will de-oxygenize ten tons Of forty per
cent iron ore. II will then take about
six hundred pounds Of coal to run the
balling furnace to put this product to
muck bar, a total Of, 1. 200 pounds of
coal. To be more explicit. 1900
pounds of coal to make one ton Of muck
bar. In the present methods employed
in making pig iron it requires 3, 600
ponds Of coal 10 the ton Of ore. In
the Jones method 1900 pounds OF coal
to ten tons Of ore.
The last run made at the furnace last
Friday evening, was ten tons Of ore,
and the expectations of Mr.. Jones, as
recorded in the above figures, were
fully realized.
The first attempt to produce proper
gas by huxing the ASH in tine coal was
! failure. The run recorded was made
on temporary reconstruction OF the
gas kiln. Mr.. Jones is now engaged
in making the permanent gas producer
and as soon as this work lie completed
e the furnace will enter into commission.
: The test established that. instead OF
b taking four hours as was estimated in
n the preliminary plans for the furnace,
: the deoxygenizing occurs in from
twenty TO thirty minutes. The new
: light on the subject Is that II Is con-
A dition OF gases and temperature and
not the time OF four hours As estimated.
/. The held OF operations TOR the Jones
