Mineral breakage along specific crystallographic planes in all specimens
due to fewer or weaker chemical bonds in those directions.
CF:mineral parting
A conveyance of an interest in the minerals in, on, or under a described
tract of land. The grantee is given operating rights on the land;
easements of access to the minerals are normally implied unless expressly
negated. Williams
Sp. Self-fluxing ore. Hess
a. A mass of naturally occurring mineral material; e.g., metal ores or
nonmetallic minerals, usually of economic value, without regard to mode of
origin. Accumulations of coal and petroleum may or may not be included;
usage should be defined in context. Syn:orebody
b. A mineral occurrence of sufficient size and grade that it might, under
favorable circumstances, be considered to have economic potential.

The systematically arranged information describing the essential
attributes (properties) of a class of mineral deposits. The model may be
empirical (descriptive), in which instance the various attributes are
recognized as essential even though their relationships are unknown; or it
may be theoretical (genetic), in which instance the attributes are
interrelated through some fundamental concept. See also:model
SME, 1
A machine for trimming or dressing mineralogical specimens.
Standard, 2
a. Physical and chemical concentration of raw ore into a product from
which a metal can be recovered at a profit. ASM, 1
b. Treatment of natural ores or partly processed products derived from
such ores in order to segregate or upgrade some or all of their valuable
constituents, and/or remove those not desired by an industrial user.
Mineral dressing processes are applied to industrial wastes to retrieve
useful byproducts. See also:mineral processing; ore dressing.
Pryor, 2
Study and application of the technical and administrative processes used
in management, control, and finance connected with the discovery,
development, exploitation, and marketing of minerals. Pryor, 3
The physical aggregate of mineral occurrences in a region above some lower
cutoff. Shanz
Term covers a wide field in which many resources of modern science and
engineering are used in discovery, development, exploitation, and use of
natural mineral deposits. Pryor, 3
The filing of a claim for public land to obtain the right to any minerals
it may contain. Craigie
See:ozocerite
a. Fibrous mineral whose fibers are longer than 5 mu m and with an aspect
ratio (length over width) equal to or greater than 3:1 as determined by
the membrane filter method at 400X to 500X magnification (4-mm objective)
phase contrast illumination. ACGIH, 1
b. The smallest elongated crystalline unit that can be separated from a
bundle or appears to have grown individually in that shape, and that
exhibits a resemblance to organic fibers. Campbell
Scot. A tract of country in which workable minerals are found; a mineral
leasehold.
A finely pulverized inert mineral or rock that is included in a
manufactured product--e.g., paper, rubber, and plastics--to impart certain
useful properties, such as hardness, smoothness, or strength. Common
mineral fillers include asbestos, kaolin, and talc. AGI
Coal or petroleum. See also:fossil fuel
Two or more mineral species having identical or closely related
structures; e.g., hematite group or zeolite group. See also:mineral
Mineral interests in land means all the minerals beneath the surface. Such
interests are a part of the realty, and the estate in them is subject to
the ordinary rules of law governing the title to real property.

An accounting of the mineral reserves and resources contained in known
mineral deposits including inactive mines, operating mines, and
undeveloped sites. Shanz
The process or processes by which a mineral or minerals are introduced
into a rock, resulting in a valuable or potentially valuable deposit. It
is a general term, incorporating various types; e.g., fissure filling,
impregnation, and replacement. AGI
