In ore processing, the period during which pulp is agitated with a given
chemical, or combination of chemicals, in the series of conditioning
operations that precede separation of various minerals in the ore by froth
flotation. Pryor, 1
Intermediate flotation products that may be re-treated. BS, 5
Oil, such as creosote oil, pine oil, or turpentine. Used to wet a
particular component of a powdered material and cause it to concentrate in
an airy froth. Bennett
Plane of a liquid surface in which a body floats. Hess
See:flotation; oil flotation.
Any of several reagents used in the froth flotation process. They include
pH regulators, slime dispersants, resurfacing agents, wetting agents,
conditioning agents, collectors, and frothers. Pryor, 3
An acid or an alkali used to control the pH of flotation solutions.
Bennett
The time necessary to make the separation into concentrate and tailing
depends on such factors as particle size and reagents used, and must be
known for determination of the size and number of flotation cells in the
plant. Fuerstenau
A synthetic reagent of the general nature of pine oil; used as frother in
flotation process. Pryor, 3
a. Any moss agate.
b. A term applied to any moss agate or mocha stone with flowerlike
markings.
c. Translucent chalcedony from Oregon containing inclusions of minerals,
some red, brown, or yellow and green, arranged in flowerlike forms,
commonly both red and green.
Very fine scaly native copper that floats on water and is very difficult
to save in milling. See also:float copper
The finely granulated condition of quicksilver, produced to a greater or
lesser extent by its agitation during the amalgamation process. The
coating of quicksilver with what appears to be a thin film of some
sulfide, so that when it is separated into globules these refuse to
reunite. Also called flouring. See:sickening
See:float gold
See:gypsum
Very fine-grained vacuum pan salt. Kaufmann
Fine-grained, highly calcined, powdery textured alumina; also dusty,
easily airborne. Traditionally produced by European Bayer plants.
a. The plastic deformation of solids: flowage; solid flow; rock flowage;
plastic flow. CF:fracture
b. That which flows or results from flowing. A mass of matter moving, or
that has moved in a stream, such as a lava flow. Syn:current
Fay
c. The movement of a fluid, such as air, water, or magma (lava).
AGI
d. A tabular-shaped body of lava that consolidated from magma on the
surface of the Earth. AGI
e. In ceramics, the flux used to cause color to run and blend in firing.
Fay
f. A mass movement of unconsolidated material that exhibits a continuity
of motion and a plastic or semifluid behavior resembling that of a viscous
fluid; e.g., creep; solifluction; earthflow; mudflow; debris flow;
sturzstrom. Water is usually required for most types of flow movement.
AGI
g. The mass of material moved by a flow. The smallest formal
lithostratigraphic unit of volcanic flow rocks. A flow is a discrete,
extrusive, volcanic body distinguishable by texture, composition, order of
superposition, paleomagnetism, or other objective criteria. It is part of
a member and thus is equivalent in rank to a bed or beds of
sedimentary-rock classification. Many flows are informal units.
Designation of flows as formal units should be limited to those that are
distinctive and widespread. AGI
See:flow
a. The retarding effect produced by walls on the movement under the
influence of pressure of a mush of crystals in a magmatic liquid, which
may give rise to magmatic differentiation and also to the concentration of
ore minerals. Schieferdecker
b. The tendency of suspended crystals to concentrate in the high-velocity
zone of a magma that is moving by laminar flow. AGI
A minor fold that is the result of the flowage of rocks toward a synclinal
axis, toward which the minor folds are overturned.
