See:glaciofluvial
Of or pertaining to sedimentation partly in lake water and partly in
streams, or to deposits laid down under alternating or overlapping
lacustrine and fluviatile conditions.
Consisting of or pertaining to the land and its streams. AGI
a. See:fluxstone
b. To cause to become fluid; to treat with a flux, esp. to promote fusion;
to become fluid. Syn:flow
c. Any chemical or rock added to an ore to assist in its reduction by
heat; e.g., limestone with iron ore in a blast furnace.
d. In metal refining, a material used to remove undesirable substances;
e.g., sand, ash, or dirt, as a molten mixture.
An iron-ore pellet made by mixing minor amounts of a ground flux
(forsterite, calcite, dolomite, or lime) with the magnetite or hematite
concentrate to decrease smelting times and coke consumption.
A method of growing refractory crystals; similar in many respects to
crystallization for aqueous solutions, but the fluxes are salts with
relatively high melting temperatures.
An instrument used for detailed studies of the Earth's magnetic field on a
local basis that uses the flux-gate, which consists of two identical
saturable cores of high permeability, with identical, but oppositely
wound, coils. An alternating current in these coils magnetizes them first
with one polarity, then in the opposite sense. If an additional field is
present, such as the Earth's field, it will add to the flux in one coil
while decreasing that in the other, resulting in different voltage drops
across the two coils. This difference is proportional to the unvarying
field, which can be measured by noting the average voltage difference
between the two halves of the flux gate. In use, a part of the Earth's
field is balanced out by an additional winding surrounding both cores and
carrying direct current. In airborne use, the recording flux gate is kept
aligned with the magnetic field by the use of two additional flux gates.
When these are at right angles to the Earth's field, they generate no
voltage, but if they depart from this position, they can generate voltages
which operate motors returning them to proper alignment. In this fashion,
the recording element is held always parallel to the total field.
Hunt
Fusion or melting of a substance as a result of chemical action.
Harbison-Walker
Lump or pebble quicklime used for fluxing in steel manufacture. The term
may be applied more broadly to include fluxing of nonferrous metals and
glass. It is a type of chemical lime. Boynton
An ore containing an appreciable amount of valuable metal, but smelted
mainly because it contains fluxing agents that are required in the
reduction of richer ores. Weed, 2
Consists of pure limestone or sometimes dolomite and is used in iron blast
furnaces and foundries. Usually material below 2 in (5.1 cm) in diameter
is eliminated. The most desirable size is between 4 in and 6 in (10 cm and
15 cm). USBM, 7
Banding in rock consisting of flow layers.
See:flow structure
A small ladle for dipping up a sample of molten metal for testing.
Fay
a. Limestone, dolomite, or other rock or mineral used in metallurgical
processes to lower the fusion temperature of the ore, combine with
impurities, and make a fluid slag. Syn:flux
b. Crushed limestone or dolomite used as a flux in the smelting of iron
ore.
c. In iron-ore pelletizing, a mixture of ground limestone and dolomite
added to the iron ore before the concentrate is rolled into green balls
and fired at 1,315 degrees C in a pelletizing furnace. Also spelled
fluxing stone; flux stone.
a. An opening in a chute that can be opened or closed at will. In a chute
for coal, a fly gate may be inserted so that if rock is deposited in the
chute, it may be trapped out by opening the fly gate. Zern
b. An opening or bypass in a chute or hopper that can be opened or closed
at will for diverting ore, rock, or coal from one bin or conveyor to
another. Sometimes called "to fly."
A submersible pump developed in Sweden.
Eng. See:cradle
Aust. A broken, discontinuous, irregular vein.
A pattern of mineral-deposit veins overlapping and intersecting in a
branchlike pattern. AGI
Rocks propelled from the blast area by the force of an explosion.
