Definition of gangue in English: ganguenoun ɡaŋɡæŋ mass nounThe commercially valueless material in which ore is found. （无商业价值的）矸石；脉石；尾矿；矿渣 good ore with some gangue or rock adhering Example sentencesExamples - The major ore and gangue minerals are given in the table, but only those of interest to collectors are discussed in detail below.
- A short drift and crosscut were driven off the back of the cavity in search of ore, but only low-grade mineralization consisting of chalcopyrite, galena, and sphalerite in a siliceous gangue was encountered.
- At that time, the museum acquired the Colorado State Collection, which has high historical value because it contains many ore and gangue specimens from now-closed and abandoned Colorado mines.
- Chlorite, predominantly magnesium chlorite, is the principal gangue, and its intimate association with the uraninite indicates that the two minerals formed together.
- Specifically, gangue formed by both metasomatic alteration and precipitation during ore formation can yield a wealth of information about the origins and physical conditions of the ore-forming fluids.
- The main gangue minerals are quartz and barite.
- The main ore minerals are galena, chalcopyrite, sphalerite, and tetrahedrite that are associated with quartz and barite gangue.
- The fluorite is typically a gangue mineral and is only locally recovered as an ore.
- The main gangue minerals that make up the vein are massive white calcite, quartz, and prehnite.
- Don't you think that in some cases these nuggets have got to be cleared of their gangue?
- It is associated with all ore minerals as well as most gangue minerals.
- Uraninite occurs with cobalt, nickel, arsenic, and silver minerals in a carbonate gangue at the Solitaria mine, Jaguel district, Argentina.
- Here, too, the veins may be monomineralic, commonly quartz or calcite, but more usually are polymineralic with a mixture of metalliferous sulphide or oxide minerals and gangue minerals.
- Here the galena is massive, with 1-3 - mm-wide cleavage planes scattered across the quartz gangue surface of the specimen.
- They noted that in the Champion mine siderite is abundant, occurring as the chief gangue mineral of the sulfide ores in the dolomitic beds in the Sawatch Quartzite.
- Native copper and a host of gangue minerals were deposited in fissure veins, brecciated and fractured vesicular lava flow tops, and conglomerate beds during the same period of metal mineralization.
- Rhodonite is described in the technical literature as a widespread and locally abundant gangue mineral in many of Colorado's precious-metal vein deposits.
- Exceptionally well-crystallized zinc-bearing rhodonite was a locally abundant gangue mineral at Franklin and, to a lesser extent, Sterling Hill, Sussex County, New Jersey.
- Rhodonite is found as a gangue mineral in hydrothermal silver veins cutting volcanic rocks in the Pacocollo, Carangas, and Todos Santos areas, Bolivia.
- It is a gangue mineral in ores from the Star, Hobo, and Princess mines at Central, Grant County.
