Cov xwm txheej tam sim no ntawm Regenerated Hlau ntau lawm nyob rau hauv lub ntiaj teb no ntawm hluav taws xob cua sov Tube Electroplating
Feem ntau ntawm cov hlau hauv ntiaj teb tuaj yeem siv tau ua cov hlau siv dua tshiab. Regenerated hlau tuaj yeem muab faib ua ob pawg: ib qho yog lub ces kaum scraps txiav los ntawm cov chaw tsim khoom thaum lub sij hawm ua cov khoom hlau, uas yog cov tshiab refined hlau. Peb hu rau lawv "cov khoom siv tshiab", thiab lwm qhov yog kev rov ua dua tshiab ntawm cov khoom siv hlau khib nyiab (cov khoom tiav), uas peb hu ua "cov ntaub ntawv qub". Cov ntaub ntawv tshiab crushed tuaj yeem siv ncaj qha tom qab tau yaj rov qab rau hauv qhov cub, thaum cov ntaub ntawv qub yuav tsum tau muab tshem tawm, txheeb xyuas, tshem tawm impurity, melted, thiab muaj pes tsawg leeg kho ua ntej rov siv dua.
Muaj ntau tshaj 30 hom hlau uas tau rov ua dua tshiab, suav nrog hlau thiab hlau, manganese, chromium, cobalt, vanadium, titanium, tungsten, tin, molybdenum, mercury, aluminium, tooj liab, lead, zinc, nickel, magnesium, beryllium, niobium. , tantalum, kub, nyiaj, platinum pab pawg hlau, cadmium, gallium, indium, selenium, thiab zirconium.
Tam sim no, kwv yees li 40 feem pua ntawm cov khoom siv raw rau cov hlau tsis huv hauv ntiaj teb yog los ntawm kev rov ua dua thiab siv cov khoom seem. Nyob rau hauv 2004, lub ntiaj teb no tsim 7.56 lab tons ntawm recycled txhuas, accounting rau 25.18 feem pua thiab 25.61 feem pua ntawm cov refined txhuas ntau lawm thiab noj; Hauv xyoo 2004, lub ntiaj teb tau tsim 5.47 lab tons ntawm cov tooj liab rov ua dua tshiab, suav txog 35 feem pua thiab 33 feem pua ntawm cov tooj liab ua kom zoo thiab siv tau; Nyob rau hauv 2004, lub ntiaj teb no tsim 3.27 lab tons ntawm recycled txhuas, accounting rau 45 feem pua thiab 46 feem pua ntawm refined txhuas ntau lawm thiab noj; Hauv xyoo 2003, lub ntiaj teb cov khoom muaj txiaj ntsig zoo xws li kub, nyiaj, platinum, thiab palladium yog 943 tons, 6138 tons, 19. 9.15 feem pua , thiab 6.08 feem pua ntawm tag nrho cov nyiaj xyoo, nyiaj, platinum, thiab palladium hauv 2003; Regenerated zinc suav txog li 30 feem pua ntawm ntiaj teb cov zinc noj.
Industrialized lub teb chaws muaj ib tug loj scale ntawm recycled hlau kev lag luam thiab ib tug siab recycling tus nqi ntawm recycled hlau. Hauv xyoo 2003, cov khoom siv rov ua dua tshiab ntawm cov hlau, chromium, titanium, aluminium, tooj liab, lead, zinc, nickel, magnesium, thiab tin hauv Tebchaws Meskas suav txog 52 feem pua, 27 feem pua, 46 feem pua, 36 feem pua, 30 feem pua, 80 feem pua. , 26 feem pua , 44 feem pua , 46 feem pua , thiab 19 feem pua ntawm nws cov khoom muaj. Tus nqi ntawm cov khoom siv no yog $ 10.5 nphom rau steel, $ 99.2 lab rau chromium, $ 48 lab rau titanium, $ 4.23 billion rau txhuas, $ 1.77 billion rau tooj liab, $ 1.1 billion rau txhuas, $ 309 lab rau zinc, $ 899 lab rau npib tsib xee, thiab $ 168 lab. lab rau magnesium, feem.
