Molybdenum Recycling Status
Jan 31, 2024
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam molybdenum, molybdenum raw khoom noj tau loj dua thiab loj dua, cov peev txheej rov qab tau me dua thiab me dua, txhawm rau tiv thaiv ib puag ncig thiab txhim kho kev siv cov peev txheej molybdenum, txij li nruab nrab xyoo 1980s, tsim. lub teb chaws pib xyuam xim rau molybdenum regeneration cov kev pab cuam, tshwj xeeb tshaj yog cov nqi ntawm cov pov tseg catalyst uas muaj molybdenum, zoo li lub tebchaws United States nyob rau hauv 1995 los ntawm cov rov qab ntawm molybdenum los ntawm cov pov tseg catalysts muaj li ntawm 3800 tons, uas suav txog li 30% ntawm tag nrho cov. muab. Tsis tas li ntawd, molybdenum recycling cov kev pab cuam nyob rau hauv molybdenum cov ntsiab lus feem ntau yog siab dua molybdenum ore, los ntawm uas tus nqi ntawm extracting molybdenum thiab lwm yam hlau yog tsawg tshaj li uas muab rho tawm los ntawm cov ore, lub zog noj kuj qis dua, cov emissions kuj me me, thiab yog li ntawd. molybdenum recycling tau dhau los ua qhov tseem ceeb ntawm kev lag luam molybdenum.
Tam sim no, muaj ob qhov chaw tseem ceeb ntawm cov khoom siv thib ob ntawm molybdenum: molybdenum-muaj slag thiab cov kua khib nyiab tsim thaum lub sij hawm molybdenum metallurgical txheej txheem, thiab cov pov tseg thiab siv cov tshuaj molybdenum los yog cov khoom tsim tawm thaum lub sij hawm tsim cov khoom siv hlau molybdenum. Raws li International Molybdenum Association (IMA), ze li ntawm 80, 000 tons ntawm molybdenum tau rov ua dua xyoo 2011, suav txog kwv yees li ib feem peb ntawm tag nrho cov molybdenum noj, uas qhia tau hais tias cov khoom siv molybdenum tau dhau los ua ib feem tseem ceeb ntawm molybdenum muab saw hlau.
Lub koom haum International Molybdenum (IMA) kwv yees tias qhov kev faib ua feem no yuav ncav cuag 35% los ntawm 2030. Nyob ib ncig ntawm 60% ntawm cov khoom siv molybdenum yog siv rau hauv kev tsim cov hlau tsis muaj steel, nrog rau cov khoom seem siv hauv kev tsim cov cuab yeej alloyed steels, superalloys, high- ceev steels, cam khwb cia hlau thiab tshuaj catalysts.
