e. A long troughlike box set on a slope of about 1:20, through which
placer gravel is carried by a stream of water. The sand and gravel are
carried away, while most of the gold and other heavy minerals are caught
in riffles or a blanket on the floor. See also:box sluice;
ground sluice; placer mining. Nelson
f. See:flume
g. An opening in a structure for passing debris. Seelye, 1
h. A channel, drain, or small stream for carrying off surplus or overflow
water. Craigie
Long, inclined trough or launder containing riffles in the bottom that
provide a lodging place for heavy minerals in ore concentration. The
material to be concentrated is carried down through the sluices on a
current of water. Sluiceboxes are widely used in placer operations for
concentrating elements such as gold and platinum, and minerals such as
cassiterite, from stream gravels. Newton, 1
A form of fork having many tines, used to remove obstructions from a
sluiceway.
The sliding gate of a sluice. Webster 3rd
Aust. A supply of 1 ft3 /s (0.028 m3 /s) of water,
regardless of the head, pressure, or size of orifice. CF:miner's inch
In metal mining, a laborer who tends sluiceboxes (troughs) used in placer
mining to separate gold from the sand or gravel in which it occurs; and
removes wood and other obstructions to see that the gravel and water run
freely through the sluices and that the riffles (cleats) are clear, so
that the gold will be caught and held when settling to the bottom.
DOT
An artificial channel into which water is let by a sluice.
Webster 3rd
Concentrating heavy minerals by washing unconsolidated material through a
box (sluice) equipped with riffles that trap the heavier minerals on the
floor of the box. AGI

d. Used in the plural for the discharge or waste from hydraulic mines.
See also:tailing; slime.
A usually red, muddy deposit in mining sluices. Webster 3rd
a. A landslide characterized by a shearing and rotary movement of a
generally independent mass of rock or earth along a curved slip surface
(concave upward) and about an axis parallel to the slope from which it
descends, and by backward tilting of the mass with respect to that slope
so that the slump surface often exhibits a reversed slope facing uphill.
Syn:slumping
b. The mass of material slipped down during, or produced by, a slump.
AGI
A term applied loosely to any disturbed bedding; specif. deformed bedding
produced by subaqueous slumping or lateral movement of newly deposited
sediment. AGI
The downward movement, such as sliding or settling, of a slump.
Syn:slump
Cartridges of explosive lowered into position in drill hole blasting at
the end of a length of strong twine (not wire). As detonating cord is
normally used for ignition in drill holes, the primed cartridge is lowered
first in each charge by using a detaching hook or a length of twine, and
it is followed by the remainder of the charge. Nelson
a. The fine carbonaceous discharge from a mine washery. All washeries
produce some slurry, which must be treated to separate the solids from the
water in order to have a clear effluent for reuse or discharge.
See also:sludge
b. Fine particles concentrated in a portion of the circulating water
(usually by settling) and waterborne to treatment plant of any kind.
BS, 5
c. A thin watery suspension; e.g., the feed to a filter press or other
filtration equipment. CCD, 2
