Gangue

Definitions

  • Webster's Revised Unabridged Dictionary
    • n Gangue (Mining) The mineral or earthy substance associated with metallic ore.
    • ***
Century Dictionary and Cyclopedia
    • n gangue In mining, the non-metalliferous or earthy minerals accompanying the ore in a vein or mineral deposit; the part of a lode which is not called ore, or which has no commercial value; veinstone. Quartz is the most abundant veinstone; calcite, heavy-spar, fiuor-spar, and brown-spar are also commonly found forming more or less of the bulk of the metalliferous lodes. Sometimes the gangue prevails in the vein to the entire exclusion of ore. The words gangue and veinstone are not properly used to designate the material with which the ore is associated when this consists chiefly of fragments of the country-rock mingled with fiucan, etc. This is what the miners designate as the filling-up. See vein and comb, 6.
    • n gangue In mineral analysis, the foreign material or impurity present with the mineral under examination.
    • ***
Chambers's Twentieth Century Dictionary
    • n Gangue gang in mining, the stony matrix in which metallic ores occur.
