Ua nyob rau hauv pob zeb basaltic thiab lwm yam Cu-Ni deposits nrog chalcopyrite, ilmenite thiab hais txog.
Ua nyob rau hauv hydrothermal deposits nyob rau hauv lub porphyry tooj liab ore, feem ntau muaj microscopic flake chalcopyrite inclusions, thiab chalcopyrite, pyrite, galena, zoisite, sulfur-arsenic tooj liab ore, chalcopyrite thiab lwm yam symbiotic; thiab qee zaum nrog molybdenite, ntuj kub thiab lwm yam symbiotic.
Nws kuj pom nyob rau hauv qee qhov yuccaite deposits, thiab coexists nrog lwm cov tooj liab sulfides. Hauv thaj chaw oxidizing nws tau yooj yim hloov mus rau malachite, xiav chalcopyrite, hematite, limonite thiab lwm yam.
Sulfur yog qhov teeb meem nyob rau hauv nws tsis yog xim hlau, hlau yog tam sim no, tsis tshua muaj ntiaj teb tsuas yog nyob rau hauv mines tsim nyob rau hauv Northwest, thiab tooj liab mines nyob rau hauv Inner Mongolia yog ua tau.
Hlau yog ci iab, zoo hluav taws xob conductivity, thermal conductivity thiab mechanical zog, thiab muaj qhov zoo kub tsis kam coefficient ntawm cov khoom. Hlau, yog tsev neeg loj, tam sim no muaj 86 hom hlau hauv ntiaj teb. Feem ntau cov neeg muab faib ua ob pawg ntawm cov hlau, ferrous hlau thiab non-ferrous hlau.
Ferrous hlau thiab non-ferrous hlau lub npe no, feem ntau ua rau tib neeg to taub yuam kev, xav tias ferrous hlau yuav tsum yog dub, qhov tseeb, nws tsis yog.
Tsuas muaj peb ferrous hlau: hlau, manganese thiab chromium. Thiab tag nrho peb ntawm lawv tsis yog dub! Cov hlau ntshiab yog nyiaj-dawb; manganese yog silver-dawb; chromium yog grey-dawb.
Vim hais tias saum npoo ntawm hlau feem ntau xeb, npog nrog ib txheej ntawm cov hlau dub tetraoxide thiab xim av hlau oxide sib tov, zoo li dub.
Tsis xav tias tib neeg hu nws "ferrous hlau". Lub "ferrous metallurgical kev lag luam" feem ntau hu ua hlau thiab hlau kev lag luam. Txij li cov hlau alloy feem ntau yog manganese steel thiab chromium hlau, manganese thiab chromium kuj suav tias yog "ferrous hlau".
Ntxiv rau cov hlau, manganese thiab chromium, tag nrho lwm cov hlau yog suav tias yog cov hlau tsis muaj hlau.
Muaj ntau txoj hauv kev los txheeb xyuas cov hlau tsis muaj hlau. Piv txwv li, raws li qhov tshwj xeeb lub ntiajteb txawj nqus ntawm cov ntsiab lus, aluminium, magnesium, lithium, sodium, potassium thiab lwm yam tshwj xeeb lub ntiajteb txawj nqus yog tsawg dua 5, hu ua "lub teeb hlau", thaum lub ntiajteb txawj nqus ntawm tooj liab, zinc, nickel, mercury, tin. , txhuas thiab lwm yam ntau tshaj 5, hu ua "hnyav hlau".
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
