a. A pump, usually a centrifugal type, capable of handling sand- and
gravel-laden liquids without clogging or wearing unduly. Syn:sandhog;
suction bailer. See also:gravel pump; sludge pump; swab. Long
b. A pump for lifting tailings at ore-dressing plants. Fay
c. A cylinder with a valve at the bottom, lowered into a drill hole from
time to time to take out the accumulated slime resulting from the action
of the drill on the rock. Also called shell pump; sludger. Fay
d. A piston-type bailer. Also called American pump. Long
A long pipe reaching down from a vessel into the sand, the latter being
raised under the suction of a centrifugal pump and discharged into the
vessel itself or an attendant barge. Also called a suction dredger.

A sand sampler made and used in the same manner as an American pump or
sand pump, a. Long
See:sandbar
The normal method of measuring soil density. In its simplest form, the
measurement requires only a container full of dry sand of known density, a
balance and apparatus for determination of soil moisture content.

a. A field term for a sandstone that is not firmly cemented. AGI
b. A term used in southern England for a sandstone that crumbles between
the fingers. AGI
c. See:sandstone
A metal roll cast in a mold of sand; distinguished from a chilled roll,
which is cast in an iron mold or chill. Standard, 2
a. The coarser and heavier portions of the crushed ore in a mill.
Fay
b. Tailings from the stamp mills of certain copper mines. Fay
c. Particles of crushed ore of such a size that they settle readily in
water and may be leached by allowing the solution to percolate.
CTD
Any cyanidation process for gold ores that involves separation of two
portions in a classifier, and separate treatment of sands by percolation
and slimes by agitation. Nelson
A quarry term for a more or less minute vein or dike of muscovite (white
mica) with some quartz, in cases also with feldspar.
a. A medium-grained clastic sedimentary rock composed of fragments of sand
size set in a fine-grained matrix (silt or clay) and more or less firmly
united by a cementing material (commonly silica, iron oxide, or calcium
carbonate); the consolidated equivalent of sand. The sand particles
usually consist of quartz, and the term sandstone, when used without
qualification, indicates a rock containing about 85% to 90% quartz. The
rock varies in color, may be deposited by water or wind, and contains
numerous primary features (sedimentary structures and fossils). Sandstones
may be classified according to composition of particles, mineralogic or
textural maturity, fluidity index, diastrophism, primary structures, and
type of cement. AGI
b. A field term for any clastic rock containing individual particles that
are visible to the unaided eye or slightly larger. Syn:sandrock
AGI
a. A clastic dike composed of sandstone or lithified sand; a lithified
sand dike. AGI
b. Stone intrusion. See also:horseback
In geology, a coarse, angular-grained sandstone.
A variety of opal occurring in boulders between layers of sandstone and
soft clay in the form of pipes in thickness from 1 mm to 3 cm.
a. A device for separating sand and other heavy or coarse particles from a
cuttings-laden; drill-circulation fluid overflowing the collar of a
borehole. CF:shaker
b. A device, often a simple enlargement, in a conduit for arresting the
sand, silt, etc., carried by the water, and generally including means of
ejecting them from the conduit. Seelye, 1
A temporary independent wall separated from a slag-pocket wall by a
thickness of sand for the purpose of easy slag removal and the protection
of the permanent wall. AISI
An apparatus for separating sand from earthy substances. Fay
See:arenaceous
Coarse-grained, porous, granular textured alumina that has not been
calcined to the alpha alumina stage (artificial corundum). Resembles fine
sand, hence free-flowing, with nondusting qualities. The relatively large
surface area of sandy alumina permits its use as an absorbent in dry
scrubber units at primary aluminum smelters.
a. Sp. Dark green bloodstone variegated by red spots.
b. Sp. Hematite.
