Tailings (more on explanation) Flashcards
(9 cards)
an engineered and
constructed facility to contain
tailings.
TSF
the by-products generated
from mechanical and chemical
processes used to extract a desired
product (such as gold and copper)
from ore.
Tailings
TSF Configuration
(often referred to as a cell
TSF, a ring dike TSF, or a turkey’s nest TSF)
is one where containment embankments
are constructed around the entire
facility. A ____ TSF is generally used in
areas that are very flat and have little
topographical relief
Paddock
TSF configuration
formed by constructing containment embankments
across a natural valley or drainage. The
natural topography combined with the
containment embankments forms the
primary tailings storage basin.
Cross Valley TSF
TSF Configuration
As the name implies, an ____ TSF is one
where tailings are deposited into an
inactive open pit.
in-Pit Disposal
TSF CONFIGURATION
or co-disposal of tailings
consists of mixing other materials, such as
waste rock, in a single storage area. This
approach allows the tailings to be
“stacked” by filling in the voids within the
waste rock or other media.
