The control of the discharge into watercourses (or on adjacent land), of
mineralized or impure water, or sludge, or mining debris. Nelson
The chemical assaying of drill cuttings for a specific metal or group of
metals. Long
a. See:sediment tube
b. See:calyx
Any part of the drill-string equipment clogged by impacted cuttings.
Long
a. A wooden box in which the sludge is allowed to settle from the mud
flush and sometimes retained for examination. Nelson
b. See:settling box
See:calyx
A tailrace for conveying the tailings away after the gold has been
extracted from alluvial beds.
A machine in which the sludge (slime) from another mill is washed; as,
e.g., a slime table.
Collecting or settling areas for the slurry which results from
hydraulicking overburden. Austin
See:sump
Short iron pipe or tube fitted with a valve at the lower end, with which
the sludge is extracted from a borehole. Also called bailer, mud pump.
See also:mud hog; sand pump.
a. A long cylindrical tube, fitted with a valve at the bottom and open at
the top, used for raising the mud that accumulates in the bottom of a
boring during the sinking process. Also called sand pump; shell pump;
sludge pump. CTD
b. A scraper for clearing mud out of a shothole. CTD
c. A centrifugal pump designed for dealing with sand and slime.

a. Samples of mud from a rotary drill, or sand from a churn drill, or fine
materials from diamond drilling used to obtain information about the
formation being drilled. Nichols, 1
b. All or part of the drill cuttings collected, dried, and saved for
assaying or chemical analysis. Long
c. The mud and chippings made during boring with a diamond or churn drill
and sometimes used for sampling purposes. Little reliance can be placed on
the assay of the sludge, and it is not regularly saved for assay, except
occasionally when drilling in weathered or friable ore zones. Sludge tanks
are often used to collect sludge samples. Nelson
a. An individual responsible for collecting and preparing drill cuttings
for the purpose of examining, assaying, chemical analysis, or storage.
Also called sampler. Long
b. A device used to collect and to split drill cuttings.
See also:riffle
Process of collecting and preparing drill cuttings as samples.
Long
A device for collecting all the drill cuttings from a given interval of
borehole. Long
See:rifle
See:return water
Filling or choking the waterways of a bit with drill cuttings; mudding up.
A formation from which it is nearly impossible to recover core, so that
sampling is done by collecting the drill cuttings or sludge. Long
