Copper pyrite tseem hu ua tooj liab daj ore. Cia peb tsom xam cov yam ntxwv ntawm cov tshuaj no, txheeb xyuas nws keeb kwm, muaj nyob rau hauv xwm.
tooj liab pyrite tshuav nws lub npe rau lo lus Greek "chalkos", txhais tau tias tooj liab, thiab "pyros" - hluav taws. Cov ntxhia no feem ntau hu ua chalcopyrite. Nws cov ntsiab lus tseem ceeb ntawm qhov tseem ceeb yog tooj liab pyrite.
Zoo ntawm cov tshuaj muaj pes tsawg leeg
Cov tshuaj no muaj ob yam hlau: hlau thiab tooj liab. Tseem muaj leej faj. Cov mis rau tooj liab pyrite yog CuFeS2. Cov ntxhia muaj 34.57% tooj liab (los ntawm huab hwm coj), 30.54% hlau, thiab 34.9% sulfur. Thaum ua tshuaj ntsuam xyuas, impurities ntawm nyiaj, kub, selenium, thiab tellurium tau kuaj pom nyob rau hauv nws cov muaj pes tsawg leeg. Lub compound muaj ib tug tetragonal qauv nyob rau hauv uas tooj liab thiab hlau alternate nyob ib ncig ntawm leej faj.
tooj liab pyrites nyob rau hauv cov xwm muaj peev xwm pom nyob rau hauv druse voids. Cov xim ntawm cov pob zeb hauv av yog golden daj, tooj dag daj, muaj cov xim ntsuab ntsuab, muaj xim hlau ci. Hardness yog yam ntxwv los ntawm ntau yam ntawm 3-4, cov ntxhia yog opaque, qhov ceev yog kwv yees li ntawm 4, 2.
tshuaj muaj zog
tooj liab pyrite zoo heevdissolves nyob rau hauv concentrated nitric acid, raws li ib tug tshwm sim ntawm kev sib cuam tshuam, sulfur yog tso tawm. Nws tsis yaj hauv hydrochloric (hydrochloric) acid. Insignificant etching nyob rau hauv potassium cyanide thiab nitric acid nyob rau hauv polished seem yog yam ntxwv. Cov yam ntxwv ntawm cov qauv tuaj yeem raug nthuav tawm los ntawm chav etching ntawm kev sib xyaw ntawm cov concentrated nitric thiab hydrochloric acids. Copper pyrite, daim duab uas tau nthuav tawm hauv tsab xov xwm, yog tus neeg xyuas pib zoo ntawm cov hluav taws xob tam sim no.
Thaum qhov kub nce, qhov txo qis hauv qhov kev tiv thaiv tau pom. Yog tias koj ua rau kev sib xyaw ntawm cov hlau thiab tooj liab oxides nrog hydrogen sulfide, koj tuaj yeem tau txais cov pob zeb me me ntawm chalcopyrite artificially. Nws tuaj yeem tsim nyob rau hauv cov xwm txheej hauv cov xwm txheej sib txawv. Chalcopyrite tau pom nyob rau hauv ntau yam igneous deposits, sedimentary pob zeb, hydrothermal zones.
Nyob hauv qhov xwm txheej
Raws li lub satellite, nws tau pom nyob rau hauv magmatogenic deposits ntawm sulfide tooj liab thiab npib tsib xee ores. Hydrothermal vein thiab metasomatic deposits yog suav tias yog qhov loj tshaj plaws.
tooj liab ore maj mam hloov mus rau hauv pyrite, uas yog txuam nrog pyrite, galena, sphalerite, faded ores. Nyob rau hauv xws li deposits, muaj calcite, quartz, barite, thiab ntau yam silicates raug tso cai. Thaum huab cua, kev puas tsuaj ntawm chalcopyrite tshwm sim, thiab sulfates ntawm hlau thiab tooj liab raug tsim. Kev sib cuam tshuam ntawm tooj liab ntsev nrog carbon dioxide los yog carbonates nyob rau hauv lub xub ntiag ntawm oxygen thiab dej ua rau tsim azurite thiab malachite.
Raws li satellitechalcopyrite tuaj yeem pom hauv hydrothermal deposits ntawm ntau yam sulfide ores. Nws yog suav hais tias yog ib qho tseem ceeb ntawm cov khoom sib tov thiab muaj kev ywj pheej siv. Ntawm thaj chaw ntawm peb lub teb chaws thiab cov tebchaws nyob sib ze, muaj ntau hom kab mob sib txawv, qhov twg pyrite yog cov khoom tseem ceeb ntawm tooj liab ore.
Pyrite deposits tau pom nyob rau hauv lub Urals, uas yog nyob rau hauv cov txheej ntawm sedimentary pob zeb ntawm Paleozoic hnub nyoog. Lub ntsiab ntxhia nyob rau hauv xws li ores yog pyrite. Nyob rau theem pib ntawm kev hloov pauv hauv cheeb tsam ntawm kev ntxiv sulfide theem nrab, nws tau hloov los ntawm bornite, covellite, thiab chalcocite. Cuprite, malachite, limonite, azurite tau sau tseg ntawm cov khoom siv huab cua.
Ntawm qhov kub siab tshaj qhov tso nyiaj, uas cuam tshuam nrog cov pob zeb ultrabasic lossis yooj yim, yog Sudbury (Canada), Volkovskoye deposit (Urals), Monchetunda (Murmansk cheeb tsam). Cov molybdenum thiab tungsten formations yog suav hais tias yog qhov kub siab tshaj deposits nplua nuj nyob rau hauv tooj liab pyrite.
Tus nqi siv tau
tooj liab pyrite siv li cas? Kev siv cov ntxhia no yog vim muaj cov ntsiab lus ntawm tooj liab hauv nws. Nws yog siv ob qho tib si nyob rau hauv daim ntawv dawb thiab nyob rau hauv muaj pes tsawg leeg ntawm alloys (tompac, bronze, tooj dag). Kev lag luam hluav taws xob yog cov neeg siv khoom tseem ceeb ntawm tooj liab. Cov nyiaj tau txais txiaj ntsig zoo yog siv hauv kev tsim vaj tsev, tshuaj lom neeg kev lag luam, nkoj tsim, tshuab engineering.
Nkauj HmoobHauv cov tshuaj, cov ntxhia chalcopyrite yog siv los ua cov tshuaj tua kab mob thiab tshuaj tiv thaiv kab mob. Qee tus kws kho mob siv chalcopyrite los kho eczema thiab dermatitis. Cov pob zeb hauv av pab tshem tawm npau suav phem, insomnia, ntxhov siab vim.
Qee tus neeg ntseeg tias lub pob zeb no nyiam cov hmoov zoo hauv kev lag luam. Nws yog nrhiav tom qab los ntawm cov poj niam uas npau suav ntawm kev mloog los ntawm cov opposite pw ua niam txiv. Chalcopyrite tuaj yeem siv los ua kev ntxim nyiam rau koj lub tsev. Cov ntxhia no muaj qee yam contraindications. Kev tsim txom ntawm pob zeb no ua rau muaj kev tsis haum tshuaj, ua rau cov kua tsib ntau ntxiv.
Zoo kawg
Tom qab ib tug neeg tau kawm txog kev siv tshuab smelting los ntawm ores ntawm cov hlau ntshiab, tshwj xeeb pib them nyiaj rau kev txhim kho ntau yam kev tso nyiaj. Hauv metallurgy, ib qho chaw tshwj xeeb belongs rau smelting ntawm tooj liab los ntawm ntau yam ores, nrog rau chalcopyrite. Tooj liab pyrite tshwm sim nyob rau hauv ntau thaj tsam ntawm lub ntiaj teb. Nyob ntawm qhov tob ntawm qhov chaw nyob rau hauv extraction ntawm cov pob zeb hauv av, ntau txoj kev siv. Ntawm qhov tob tob, mining yog ua los ntawm txoj kev quarry. Nrog rau qhov chaw sib sib zog nqus ntawm tooj liab ore, txheej txheem ntawm kev rho tawm cov pob zeb hauv av yuav nyuaj dua. Ntawm thaj chaw ntawm Lavxias Federation, tooj liab pyrite pom nyob rau hauv Urals, ze Norilsk, ntawm Celtic Peninsula.
Txij thaum xyoo pua 18th, cov pob zeb no tau raug mined nyob rau sab qaum teb sab hnub tuaj ntawm Salair Ridge. Muaj ib qho kev tso nyiaj ntawm tooj liab pyrite ntawm no. Nws yog qhov no ore uas geologists xav txog qhov zoo tshaj plaws ntawm lub cevthiab chemical yam ntxwv. Chalcopyrite yog tam sim no lub ntsiab ore rau zus tau tej cov ntshiab tooj liab. Cov hlau no muaj cov yam ntxwv hluav taws xob zoo heev, yog li nws yog los ntawm nws uas muaj ntau yam khoom siv hauv chav kuaj, coils raug tsim.
