Übersetzung für "Sphalerite" in Deutsch

The pyrite mineralization is accompanied by minor sphalerite, chalcopyrite, and local visible gold.

These veins bear free gold, sphalerite, galena and chalcopyrite.

These intersections all contained quartz-ankerite veins with sulphides and minor sphalerite (zinc).

Close to Guspini, at the mines of Montevecchio and Gennamari, galena and sphalerite were extracted in the past.

Greenockite (CdS), the only cadmium mineral of importance, is nearly always associated with sphalerite (ZnS).

Important minerals are, for example, chalcopyrite, bornite, covellite, chalcocite, sphalerite, marmatite, gelenite, pentlandite, millerite, heazlewoodite, carrollite, pyrites, marcasite and pyrrhotite.

As of 2014, a total of around 50 minerals and 10 varieties have been discovered here, including inter alia the well-known minerals andalusite, beryl, gypsum, haematite, muscovite, sphalerite, pyrite, topaz, wavellite and zircon, as well as various garnets, tourmalines, (dravite, elbaite, schorl) and wolframites.

According to the present invention this is achieved by making the sensor element or rather the piezoelectric layer material which is heat resistant up to at least 80° C., e.g., wurtzite or sphalerite, and to apply this layer over the entire surface of a heat-resistant, flexible supporting material, for instance flexible metal foil, such as Cu-Be foil, or metallized surface of a sheet of plastic, and further by providing the piezoelectric substrate with an electrically-conductive coating serving as a second electrode, e.g., a metal coating applied by evaporation.

According to another feature of the invention the transducer is made by directly spraying a piezoelectric film, for instance of wurtzite, sphalerite, etc., onto a flexible metal foil, e.g., Cu-Be foil, or onto the metal surface of a plastic sheet, one of whose sides at least has been metallized, and by applying as a second electrode an electrically-conductive coating, e.g., a metal film, on the piezoelectric substrate, for instance by evaporation.

In accordance with a further preferred feature, the leach residue fed to step (a) is obtained by a hot acid leaching of the residue left after the neutral leaching of the roasted zinc concentrate, which hot acid leaching is effected at a temperature from 70° C. and the boiling point of the solution, a separation of the undissolved matter consisting of a lead-silver residue preferably with an addition of gelatin or polyalcohol, a reducing leaching of the solution with an addition of sphalerite, a separation of the undissolved matter, a recycling of said undissolved matter to the roasting step, a preneutralization of the solution by an addition of calcine or leached residue, a neutralization by an addition of calcine, a separation of the leached residue, a precipitation of the iron contained in the solution and a recycling of the solution to the neutral leaching step.

The deposit appears to be zoned from silver rich, low sulphide mineralization at the top of the hole, to sphalerite and galena dominant mineralization further downhole.

Altered and sulphide mineralized units range from less than 5 metres up to 35 metres including typical VMS assemblages of chlorite, sericite and silica hosting pyrite, chalcopyrite and sphalerite mineralization.

A set of late quartz-carbonate veins are concentrated within the main mineralized zone and contain variable amounts of chalcopyrite, molybdenite, galena, sphalerite, bismuthinite, and visible gold.

In addition to a predominance of pyrrhotite, other observed sulfides include pyrite, chalcopyrite, bornite, sphalerite, and moybdenite, as well as native copper.

Sphalerite, zinc sulfide (ZnS), is the most important zinc mineral and occurs in almost every sulfured non-ferrous metal deposit, usually together with other relevant ore minerals.
