Kev cia siab rau Electroplating ntawm Regenerated Hlau hauv Hluav Taws Xob Hluav Taws Xob

Kev tsim khoom ntawm lwm cov khoom siv rov ua dua tshiab

Yuav luag txhua cov hlau tuaj yeem siv dua. Nyob rau hauv nws xyoo 2003 Mineral Yearbook, United States Geological Survey teev 27 cov hlau uas siv tau thiab xa mus rau lawv li Recycling hlau, suav nrog hlau thiab hlau, manganese, chromium, vanadium, titanium, cobalt, nickel, tungsten, tin, molybdenum, mercury, txhuas, tooj liab, txhuas, zinc, magnesium, kub, nyiaj, platinum pab pawg neeg, beryllium, niobium, tantalum, zirconium, selenium, cadmium, gallium, indium, thiab lwm yam. Cov khoom siv rov ua dua thiab cov nqi ntawm kaum hlau hauv Tebchaws Meskas nyob rau xyoo tas los no yog kuj teev. Ntawm lawv, cov uas muaj nqi ntau tshaj $ 100 lab hauv 2003 suav nrog hlau thiab hlau ($ 10.5 billion), aluminium ($ 4.23 billion), tooj liab ($ 1.77 billion), lead ($ 1.1 billion), nickel ($ 899 lab), zinc ($ 309). lab), thiab magnesium ($ 168 lab). Hauv xyoo 2003, qhov kev faib ua feem ntawm cov khoom siv hlau rov ua dua rau cov khoom muaj (mine ntau lawm ntxiv rau cov khoom siv hlau rov ua dua ntxiv rau cov khoom siv ntshiab ntxiv ntxiv rau kev khaws cia) hauv Tebchaws Meskas tau tshaj 20 feem pua, suav nrog txhuas (79.7 feem pua), hlau thiab hlau (52 feem pua), magnesium ( 46 feem pua), titanium (46 feem pua), npib tsib xee (44 feem pua), txhuas (36 feem pua), tooj liab (29.8 feem pua), chromium (27 feem pua), thiab zinc (25.8 feem pua).

2, Kev cog lus cia siab rau kev lag luam hlau rov ua dua tshiab

Thawj Tswj Hwm Wen Jiabao tau hais tawm hauv Daim Ntawv Qhia Txog Kev Ua Haujlwm ntawm Tsoomfwv ntawm Lub Rooj Sib Tham Thib Peb ntawm Lub Rooj Sib Tham Thib Kaum Hauv Tebchaws: "Peb yuav tsum ua kom muaj zog tsim kev lag luam ncig, thiab ua kom muaj kev siv dav dav thiab rov ua dua tshiab ntawm cov peev txheej los ntawm kev siv peev txheej, kev tsim khoom, kev siv pov tseg thiab kev noj qab haus huv. " Kev rov ua dua tshiab ntawm cov hlau siv dua tshiab yog qhov tseem ceeb rau kev txhim kho kev lag luam ncig. Cov teb chaws tsim kho muaj qhov tseem ceeb heev rau kev lag luam hlau rov ua dua tshiab. Thaum kawg ntawm lub xyoo pua 20th, qhov ntsuas ntawm cov peev txheej txuas ntxiv mus rau kev lag luam hauv cov teb chaws tsim tau mus txog 250 billion US dollars; Thaum pib ntawm lub xyoo pua no, nws tau nce mus rau 600 billion US dollars; Nws cia siab tias yuav ncav cuag $ 1800 nphom hauv xyoo 2010. Muaj tag nrho ntawm 56000 lub tuam txhab hauv Tebchaws Meskas koom nrog kev lag luam no, nrog rau kev muag khoom txhua xyoo mus txog $ 236 billion thiab muab 1.1 lab txoj haujlwm. Hauv xyoo 2004, 58 feem pua ​​​​ntawm cov hlau hauv Tebchaws Meskas tau tsim los ntawm cov khoom seem, 100 feem pua ​​​​ntawm cov khoom ua kom zoo nkauj yog los ntawm cov khoom siv txhuas, 88 feem pua ​​​​ntawm cov tooj liab refined yog los ntawm cov tooj liab siv dua, thiab 58 feem pua ​​​​ntawm cov hmoov txhuas refined yog los ntawm cov hlau lead. . Nyob rau xyoo 2004, Nyiv kuj tau tsim 100 feem pua ​​​​ntawm cov khoom ua kom zoo txhuas los ntawm cov khoom siv rov ua dua tshiab, 93 feem pua ​​​​ntawm cov tooj liab refined yog los ntawm cov tooj liab siv dua, thiab 66 feem pua ​​​​ntawm cov hlau lead ua kom zoo yog los ntawm cov hlau lead. Qhov kev faib ua feem ntawm cov teb chaws tsim kev lag luam siv cov hlau siv dua tshiab yog siab. Los ntawm kev xav thoob ntiaj teb, xyoo 2004, kev tsim cov hlau rov ua dua tshiab rau txhuas, tooj liab, txhuas, thiab zinc suav txog 25 feem pua, 35 feem pua, 45 feem pua, thiab 20 feem pua ​​​​ntawm cov hlau ua kom zoo, raws li, thiab suav txog 25 feem pua, 33 feem pua, 46 feem pua, thiab 30 feem pua ​​ntawm kev noj.
