A gravity anomaly calculated after corrections for latitude, elevation, and terrain. Pron: boo-gay.
Industry:Mining
A gravity anomaly calculated from a theoretical model and elevation above sea level, but without allowance for the attractive effect of topography and isostatic compensation.
Industry:Mining
A gravity concentrator utilizing vertical pulsations in a hydraulic medium to separate particles by specific gravity differences.
Industry:Mining
A gravity meter or gravimeter constructed so that a high sensitivity is achieved at certain positions of the elements of the system; i.e., equilibrium between a negative restoring force and the force of gravity at such positions.
Industry:Mining
A gray or white, malleable, ductile, metallic element. Symbol, V. Found in about 65 different minerals, among which are carnotite, roscoelite, vanadinite, and patronite; also found in phosphate rock, certain iron ores, and some crude oils. About 80% of the vanadium now produced is used as a ferrovanadium or as a steel additive; also used in ceramics, as a catalyst, and in the production of a superconductive magnet.
Industry:Mining
A gray, black, and yellow mottled ore of carnotite and vanoxite, its spotted appearance resembling that of a rattlesnake.
Industry:Mining
A gray, nickeliferous iron, Fe<sub>2</sub>Ni<sub>5</sub>or FeNi<sub>3</sub>. Massive, granular, and forms the metallic portion of rolled pebbles. From Josephine County, OR.
