Tam sim no, muaj 129 zinc refinery nyob rau hauv lub ntiaj teb no, suav nrog 79 thawj zinc refineries, 50 thib ob zinc refineries, thiab 12 loj thiab nruab nrab cov zinc smelters nyob rau hauv lub tebchaws United States.
Regenerated zinc los ntawm ntau yam zinc pov tseg cov ntaub ntawv, nrog rau cov khoom pov tseg tshiab thiab qub. Cov khib nyiab tshiab yog hais txog cov khoom pov tseg thaum lub sij hawm tsim cov zinc hlau thiab kev tsim khoom ntawm lwm yam khoom xws li galvanized steel, tooj dag qhov chaw, zinc tuag castings, thiab lwm yam siv hlau zinc; Cov khib nyiab qub yog hais txog cov khoom pov tseg tom qab siv cov khoom siv tsheb, cov ntawv zinc ru tsev, cov khoom siv hauv tsev, thiab lwm yam khoom siv zinc.
Nyob rau hauv 2003, Tuam Tshoj tsim 32400 tons ntawm recycled zinc, accounting rau 1.4 feem pua ntawm lub teb chaws refined zinc ntau lawm. Qhov no tsis haum rau Tuam Tshoj txoj kev noj ntau ntawm cov zinc refined, thiab muaj qhov sib txawv tseem ceeb piv rau cov teb chaws tsim muaj kev lag luam.
6. Kev tsim cov khoom siv uas muaj txiaj ntsig zoo dua qub
Ntau lub teb chaws muaj kev lag luam tseem ceeb heev rau kev rov ua dua tshiab ntawm cov khoom siv hluav taws xob zoo dua qub. Lawv tau muab cov khoom pov tseg ntawm cov hlau muaj txiaj ntsig zoo rau ntawm qhov sib npaug nrog kev txhim kho cov peev txheej ntxhia, thiab tsim kom muaj kev tswj hwm kev lag luam uas muaj nuj nqis hlau rov ua dua tshiab. Cov teb chaws tsim kho tau txais txiaj ntsig ntau ntawm cov hlau muaj txiaj ntsig los ntawm cov peev txheej thib ob txhua xyoo. Raws li kev txheeb cais, mining 1 tuj nyiaj yuav tsum kwv yees li 300000 yuan hauv tus nqi, thaum rov qab 1 tuj nyiaj tsuas yog 10000 yuan; Extracting ib ooj kub nqi $250-300, thaum rov qab ib ooj kub tsuas yog $100.
Cov khoom siv tseem ceeb ntawm cov khoom siv hluav taws xob zoo yog cov khoom siv hluav taws xob zoo nkauj, cov khoom siv, thiab cov khoom siv pov tseg siv hauv kev tsim cov hniav nyiaj hniav kub thiab cov khoom siv, cov khoom siv hluav taws xob electroplating khib nyiab (kua), cov khoom siv hluav taws xob pov tseg, hluav taws xob pov tseg, nrog rau cov dej khib nyiab thiab cov khoom siv pov tseg. kev yees duab studios, tsev kho mob radiology departments, luam ntawv factories, electroplating factories, iav factories, xov tooj cua chaw nres tsheb, hluav taws xob hloov factories, thiab lwm yam units.
Hauv xyoo 2003, kev muab cov khoom siv rov ua dua tshiab xws li kub, nyiaj, platinum, thiab palladium hauv ntiaj teb yog 943 tons, 6138 tons, 19.86 tons, thiab 14.42 tons, raws li, suav txog 22.77 feem pua, 21.77 feem pua. , 9.15 feem pua , thiab 6.08 feem pua ntawm tag nrho cov khoom siv ntawm cov hlau tseem ceeb hauv ntiaj teb hauv xyoo 2003. Xyoo 2004, Tebchaws Asmeskas tau rov qab tau 95 tons ntawm kub los ntawm cov khoom qub thiab qub, suav txog 50 feem pua ntawm nws cov khoom siv hauv tsev; 1700 tons ntawm cov nyiaj thiab 8 tons ntawm platinum pab pawg hlau kuj tau rov qab los ntawm cov khoom pov tseg tshiab thiab qub.
