Dab tsi yog cov hlau tsis-ferrous muaj nyob rau hauv tooj liab ore?
Ua nyob rau hauv cov pob zeb yooj yim thiab cuam tshuam Cu-Ni thiab lwm yam deposits, nws yog symbiotic nrog chalcopyrite, ilmenite, thiab lwm yam.
Bornite ua nyob rau hauv hydrothermal deposits feem ntau muaj microscopic lamellar chalcopyrite inclusions, thiab yog tov nrog chalcopyrite, pyrite, galena, tetrahedrite, sulfur-arsenic copperite, chalcocite, thiab lwm yam. Symbiotic; qee zaum symbiotic nrog molybdenite, ntuj kub, thiab lwm yam.
Kuj pom nyob rau hauv ib co skarn deposits, symbiotic nrog rau lwm yam tooj liab sulfides. Hauv thaj chaw oxidation, nws yooj yim hloov mus rau malachite, azurite, cuprite, limonite, thiab lwm yam.
Sulfur yog ib qho teeb meem, tsis yog hlau. Hlau yog tam sim no, tab sis lub ntiaj teb tsis tshua muaj tsawg. Tshwj tsis yog tias nws yog kuv li tsim nyob rau sab qaum teb sab hnub poob, nws muaj peev xwm ua tau rau lub pob zeb tooj liab hauv Inner Mongolia.
Hlau yog ib yam khoom uas muaj luster, zoo hluav taws xob conductivity, thermal conductivity thiab mechanical zog, thiab muaj ib tug zoo kub kuj coefficient. Cov hlau yog ib tsev neeg loj. Tam sim no muaj 86 hom hlau nyob hauv ntiaj teb no. Feem ntau tib neeg faib cov hlau ua ob pawg loj, ferrous hlau thiab non-ferrous hlau.
Cov npe ferrous hlau thiab non-ferrous hlau feem ntau ua rau tib neeg to taub yuam kev tias ferrous hlau yuav tsum yog xim dub, tab sis qhov no tsis yog li ntawd.
Tsuas muaj peb hom ferrous hlau: hlau, manganese thiab chromium. Thiab tsis muaj leej twg yog cov dub! Cov hlau ntshiab yog nyiaj-dawb; manganese yog silver-dawb; chromium yog grey-dawb.
Vim hais tias ntawm cov hlau feem ntau rusty, nws yog them nrog ib tug sib tov ntawm dub ferric oxide thiab tan ferric oxide, uas zoo li dub.
Tsis xav tias tib neeg hu nws "dub hlau". Feem ntau hu ua "ferrous metallurgical kev lag luam" feem ntau yog hais txog kev lag luam steel. Vim tias cov hlau alloy feem ntau yog manganese steel thiab chromium hlau, tib neeg xav txog manganese thiab chromium ua "dub hlau".
Tsuas yog cov hlau, manganese, thiab chromium, tag nrho lwm cov hlau yog suav tias yog cov hlau tsis muaj hlau.
Hauv cov hlau tsis-ferrous, muaj ntau yam kev faib tawm. Piv txwv li, raws li lub ntiajteb txawj nqus tshwj xeeb, txhuas, magnesium, lithium, sodium, potassium, thiab lwm yam muaj lub ntiajteb txawj nqus tsawg dua 5 thiab hu ua "lub teeb hlau", thaum tooj liab, zinc, nickel, mercury, tin, lead, thiab lwm yam. . muaj ib lub ntiajteb txawj nqus ntau tshaj 5 thiab hu ua "hnyav hlau".
