Molybdenum ua li cas?

Cov mined ore yog crushed, hauv av, tov nrog kua tshuaj thiab aerated nyob rau hauv ib tug flotation txheej txheem cais cov metallic minerals los ntawm lub pob zeb tsis muaj nqi. Qhov tshwm sim molybdenite concentrate, uas muaj 85 mus rau 92 feem pua ​​​​molybdenum disulfide (MoS2), yog ci hauv huab cua ntawm 500-650 degree los ua ib qho roasted molybdenum concentrate los yog molybdenum roasting xuab zeb (MoO3), tseem hu ua industrial molybdenum oxide. Kwv yees li ntawm 40-50% ntawm molybdenum yog siv rau hauv daim ntawv no, feem ntau yog cov khoom siv alloying hauv steelmaking. Kwv yees li 30-40% ntawm kev lag luam molybdenum oxide yog ua tiav rau hauv ferromolybdenum (FeMo). Muaj molybdenum oxide yog tov nrog hlau oxide thiab txo nrog ferrosilicon thiab txhuas nyob rau hauv ib tug aluminothermic cov tshuaj tiv thaiv. Qhov tshwm sim ferromolybdenum ingot yog crushed thiab sieved los tsim FeMo pellets ntawm qhov xav tau particle loj. Kwv yees li ntawm 20% ntawm molybdenum roasting xuab zeb ua thoob ntiaj teb tau ua tiav rau hauv ntau yam tshuaj molybdenum xws li ntshiab molybdenum trioxide (MoO3) thiab molybdates. Ammonium molybdate daws tuaj yeem hloov mus rau hauv ib qho ntawm cov khoom siv molybdate thiab ntxiv ua tiav rau hauv cov ntshiab molybdenum trioxide los ntawm calcination. Molybdenum hlau yog tsim nyob rau hauv ob-theem hydrogen txo cov txheej txheem kom muab ntshiab molybdenum hmoov.
