A metal plate that serves as partial or total support for devices used
with shaker conveyors where the device must move or slide on the bottom.
The shovel trough of a duckbill and certain types of swivels or angle
troughs use this device. Jones, 1
a. Extremely fine sediment (#200 mesh), produced in the processing of ore
or rock, esp. phosphate rock, which remains suspended in water
indefinitely. Consists chiefly of clay.
b. A material of extremely fine particle size encountered in ore
treatment. ASM, 1
c. Anode slimes are the metals or metal compounds left at, or falling
from, the anode during electrolytic refining of metals.
See also:anode slime
d. A mixture of metals and some insoluble compounds that forms on the
anode in electrolysis. ASM, 1
e. A product of wet grinding containing valuable ore in particles so fine
as to be carried in suspension by water; chiefly used in the plural.
Webster 3rd
f. In metallurgy, ore reduced to a very fine powder and held in suspension
in water so as to form a kind of thin ore mud; generally used in the
plural.
g. Primary slimes are extremely fine particles derived from ore,
associated rock, clay, or altered rock. They are usually found in old
dumps and in ore deposits that have been exposed to climatic action; they
include clay, alumina, hydrated iron, near-colloidal common earths, and
weathered feldspars. Secondary slimes are very finely ground minerals from
the true ore. Pryor, 2
In mineral processing, adherence of an impalpably fine layer of particles
of another (for example, calcite on galena), therefore hindering or
preventing true surface reaction in leaching or flotation.
Pryor, 3
In beneficiation, smelting, and refining, a laborer who washes slime from
cloth strainers, electrolysis tank debris, and collection barrels into a
settling tank, using a water spray preparatory to recovery of precious
metals from slime. Becoming obsolete. DOT
A leaching method in which the slime and the leach solution are agitated
in one or more agitators until the ore minerals have been dissolved. Some
agitators have mechanically driven paddles or elevators inside an
agitation tank, which serve to keep the pulp in circulation until
dissolution is complete. This method may be either continuous or
intermittent. Newton, 1
A tank or large reservoir of any kind into which the slimes are conducted
in order that they may have time to settle, or in which they may be
reserved for subsequent treatment. See also:slime
A machine that makes slime; e.g., a tube mill. Fay
a. The pulp or fine mud from a drill hole.
b. See:slime
a. A table for the treatment of slime; a buddle.
b. A shaking table used in gravity concentration of finely ground coal or
ore, characterized by special riffles and shallow pools in which
stratification is gently produced. Pryor, 3
Cassiterite too finely ground to be readily concentrated by the use of
gravity treatment. Usually associated with hydrated iron. Pryor, 3
Water defiled in washing ore. Standard, 2
a. A rotary borehole having a diameter of 12.7 cm or less. AGI
b. A drill hole of the smallest practicable size, often drilled with a
truck-mounted rig; used primarily for mineral exploration or as a
stratigraphic or structure test. See also:structure test hole
AGI
Use of the smallest feasible drill hole and casing size. Williams
Overgrinding in a ball mill. Newton, 1
a. Mid. Potholes in a mine roof.
b. The principal cleat in coal.
c. A natural transverse cleavage of rock; a joint.
a. A rope or chain put around stones or heavy weights for raising them.
Zern
b. A lifting hold consisting of two or more strands of chain or cable.
Nichols, 2
c. A ropelike device used to give additional support to lengths of drill
rod too long to stand in the drill derrick without sagging unduly.
Long
d. A short loop or length of cable with small loops at either end.
Long
A frame in which two sheaves are mounted so as to receive lines from
opposite directions. Nichols, 1
See:Storrow whirling hygrometer
A hygrometer held on a short length of cord and whirled around, the
observer standing sideways to the air current. The wet bulb is thereby
rapidly reduced to its final reading. Hammond
Scot. A wide clayey joint; a stage.
a. Landslip, or subsiding mass of rock or clay in a quarry or pit; a minor
landslide.
b. A small fault.
c. The relative displacement of formerly adjacent points on opposite sides
of a fault, measured in the fault surface. See also:dip slip;
strike slip. Partial syn: shift. Syn:total displacement
d. A joint or cleat in a coal seam.
e. See:kettle bottom
f. A joint in coal upon which there may have been no perceptible movement.
g. See:back
h. A joint or pronounced cleavage plane. Mason
i. A sudden descent of a hanging or sticking charge in a blast furnace.
j. One of a set of serrated-face wedges that fits inside the spider of a
drill-rod clamping device. See also:spider; slips. Long
k. The percentage of water leaking through valves, expressed as a
percentage of the volume swept out by the bucket or ram, a measure of the
volumetric efficiency of a pump. Generally for normal pumping speeds, the
slip is between 5% and 10% but it may rise to 20% with higher pumping
speeds. Sinclair, 4
l. Under stress, minerals deform plastically along specific
crystallographically determined slip planes in slip directions, analogous
either to the sliding in a deck of playing cards, such as in quartz, or to
a bundle of pencils, such as in olivine. Deformation lamellae may be
preserved or destroyed by annealing. Although such slip is referred to as
glide, it is not to be confused with a crystallographic glide--the
combined symmetry element of translation and reflection. CF:glide;
glide direction; glide plane; gliding.
