A suffix meaning "in the form of." AGI
In poikilitic fabric, the enclosing crystal. AGI
A coal beneficiation process in which an oil is used to preferentially wet
the coal particles, which have an affinity to agglomerate into masses that
are then selectively removed by screening, e.g.
See also:selective agglomeration
The residuum from the distillation of petroleum. When paraffin is obtained
from petroleum, the original oil is said to have a paraffin base; when the
residue is entirely asphaltic, the original petroleum is said to have an
asphaltic base. Some petroleums have both an asphaltic and a paraffin
base. API, 1
Shale impregnated with petroleum. Not to be confused with oil shale.
Tomkeieff
A term used in flotation when a particle is given a water repellent
surface. When such a coating has been formed, the particle is said to be
oiled or treated and ready to be floated. Newton, 1
a. In flotation, oil that provides a film around a mineral particle.
b. One of several types of mechanical devices that deliver oil to machines
and into air or steam lines in controllable amounts. Also called atomizer;
line oiler; lubricator; oil pot; pineapple; pot. Long
An extremely powerful low-speed winch on a crawler tractor.
Nichols, 1
A process in which oil is used in ore concentration by flotation.
Syn:flotation process
Concentrated sulfuric acid.
See:line oiler; oiler.
A hydraulic pump supplying oil under pressure to the hydraulic-feed
cylinders and pistons of a hydraulic-type swivel head on a diamond drill.
Long
A kerogen-bearing, finely laminated brown or black sedimentary rock that
will yield liquid or gaseous hydrocarbons on distillation.
CF:bituminous shale
petrolo-shale. AGI
A fine-grained stone used for sharpening edged tools or other similar
metal surfaces. Fay
To harden steel by quenching in oil after heating. Webster 3rd
A triclinic mineral, Ca10 Si18 O46 .18H2 O ;
white; fibrous; commonly associated with zeolites in basalts.
a. The stage in the development of a stream at which erosion is decreasing
in vigor and efficiency, and aggradation becomes dominant as the gradient
is reduced. It is characterized by a broad open valley with a flood plain
that may be 15 times the width of the meander belt; numerous oxbows,
bayous, and swamps; a sluggish current; and slow erosion, effected chiefly
by mass-wasting at valley sides. AGI
b. The final stage of the cycle of erosion of a landscape or region, in
which the surface has been reduced almost to base level and the landforms
are marked by simplicity of form and subdued relief. It is characterized
by a few large meandering streams flowing sluggishly across broad flood
plains, separated by faintly swelling hills, and having dendritic
distributaries; and by peneplanation. AGI
c. A hypothetical stage in the development of a coast, characterized by a
wide wave-cut platform, a faintly sloping sea cliff pushed far inland, and
a coastal region approaching peneplanation. The stage is probably a
theoretical abstraction, since it is doubtful whether stability of sea
level is maintained long enough for the land to be so reduced. AGI
An isometric mineral, (Ca,Mn)S ; pale brown; occurs in some meteorites and
slags; rapidly oxidizes in contact with air.
A self-contained transportable stone duster. A high-velocity current of
air from a fan or blower is mechanically fed from a hopper above, both the
fan and the feeding mechanism being driven from the tub axle as it is
drawn along by rope haulage, horse, or manually. It delivers about 3/4 lb
(0.34 kg) of dust per yard (0.9 m) of travel. Sinclair, 1
A cap lamp designed for full self-service. This lamp, weighing 6-5/8 lb
(3.0 kg), has a 4-V lead-acid battery in a hard rubber case with covers of
stainless steel or nickel-plated hard brass. The switch is magnetically
operated and is situated in a sealed plastic moulding. A 4-W bulb burning
11 h or a 2-W bulb burning 14 h is used. The lamp is of one-piece
construction and no dismantling is needed to charge the accumulator.
