Ukadaulo Waukulu Wakutayira Kopanda Vuto kwa Zotsalira za Cyanide za Golide

Njira ya cyanidation yochotsa golide, yomwe idadzitamandira zaka zopitilira 100, ikadalipo pakupanga mafakitale agolide. Kutchuka kwake kumachokera ku kuphweka kwake komanso kubweza golide wambiri. Komabe, njirayi imapanga michira yambiri ya golide. Zotsatira za cyanide zotsalira zochokera ku golide zikukula chaka chilichonse. Ziwerengero zikuwonetsa kuti bizinesi ya golidi mdziko muno imatulutsa matani pafupifupi 80 miliyoni mpaka 100 miliyoni a zotsalira za cyanide chaka chilichonse.

Kusunga kwa nthawi yayitali zotsalira za cyanide kumabweretsa mavuto angapo. Choyamba, limatenga malo ambiri. Kachiwiri, poizoni kwambiri cyanides mu zotsalira zimatha kutulutsa mpweya wapoizoni ndikupanga madzi otayira acidic. Kuphatikiza apo, ma ion achitsulo osiyanasiyana amatha kuyipitsa matupi amadzi ozungulira ndi nthaka kudzera pamadzi apamtunda kapena pansi, ndikuyika thanzi la anthu pachiwopsezo. Chodabwitsa n'chakuti, zotsalira za cyanide zochokera ku golide zimakhala ndi zinthu zamtengo wapatali monga Cu, Pb, Zn, Fe, Au, S, ndi Si zomwe zatsalira. Chifukwa chake, kulekanitsa mosamala zigawo zapoizoni, kulekanitsa bwino ndikubwezeretsanso zinthu zamtengo wapatali, ndikukwaniritsa kugwiritsa ntchito kwakukulu kwa ma cyanided tailings zakhala zofunika kwambiri pa kafukufuku wapadziko lonse lapansi.

United Chemical Co., Ltd.'s Solution: A Holistic Project

Poyankha mavutowa, United Chemical Co., Ltd. anayambitsa pulojekiti ya "Kafukufuku ndi Kugwiritsa Ntchito Makiyi Ofunika Kwambiri pa Kutaya Mopanda Vuto ndi Kugwiritsa Ntchito Zida Zotsalira za Cyanide Kuchokera ku Gold Concentrates".

Gradient - Controlled De - cyanidation ndi Flotation Recovery

"Tekinoloje Yatsopano ya Gradient - Controlled De - cyanidation and Flotation Recovery of Valuable Elements" idalandiridwa kuti ipezenso Cu, Pb, ndi Zn kuchokera kuzitsulo za golide za cyanidation. Chotsatira chake chinali chakuti mitovu ichulukidwe ndi kuyika mkuwa.

Pyrite Interface Activation and Combined Processing for Iron and Gold Recovery

Kenaka, "Tekinoloje Yatsopano ya Pyrite Interface Activation ndi Combined Mineral Processing ndi Metallurgy for Iron and Gold Recovery" inakhazikitsidwa. Tekinoloje iyi idalekanitsa bwino ndikubwezeretsa Fe ndi Si kuchokera ku michira ya de - cyanidated flotation, kutulutsa sulfure imakhazikika komanso ma silicon apamwamba kwambiri.

Sulfuric Acid ndi Iron Pellet Production

Mafuta a sulfure ankagwiritsidwa ntchito popanga sulfuric acid yochuluka kupyolera mu kuotcha mpweya wofooka. Wokazinga sulfure slag anali pellets. Pambuyo pake, "High - Temperature Iron - Gold Separation Technology" idagwiritsidwa ntchito kuti ipange ma pellets achitsulo ndi matope a golide opangidwa ndi Cu, Pb, ndi Zn.

High - Silicon Tailings Recycling

"Tekinoloje Yatsopano ya Gawo - Kusintha Malamulo ndi Zokwanira - Zobwezeretsanso Zapamwamba - Zovala za Silicon" zinathandiza kusintha masitayilo apamwamba a silicon kukhala matailosi a ceramic olowera ku Europe.

Kupita patsogolo kwaukadaulo ndi kafukufuku

Ntchitoyi idathana ndi "zovuta zinayi" zomwe zimalumikizidwa ndi zotsalira za sianidi kuchokera ku golide: kumvetsetsa bwino zinthu zapoizoni, kuwongolera ndikulekanitsa machitidwe awo, kubwezeretsanso zinthu zofunika, ndikubwezeretsanso zitsulo. Idayambitsa njira yatsopano yolumikizirana, kuphatikiza ma mineral processing, metallurgy, ndi sayansi yachilengedwe. Kafukufukuyu adatenga gawo lonse lazatsopano, kuyambira pakuvumbulutsa zomwe asayansi amapanga mpaka pakupanga matekinoloje owongolera ndikuchita ziwonetsero zaukadaulo.

Kutsogolo kwa sayansi ndi umisiri, idavumbulutsa mwadongosolo momwe zinthu zapoizoni zimachitikira mu cyanide - zomwe zimakhala ndi zinyalala zoopsa kwambiri. Pamlingo wogwiritsa ntchito, idapanga matekinoloje odzipatula motetezeka ndikutaya zinthu zapoizoni mokhazikika, kutulutsa kogwirizana kwa zigawo zamtengo wapatali, komanso kugwiritsa ntchito kwamtengo wapatali kwa zinthu zotsalira.

Zotsatira Zochititsa chidwi za Industrial Application

Pambuyo pakugwiritsa ntchito kwamakampani zomwe polojekitiyi idakwaniritsa, kuchuluka kwazitsulo zamtengo wapatali kuchokera ku zotsalira za cyanide za golidi kudapitilira 90%. Kukwaniritsidwa uku kunazindikira Kutaya kopanda vuto ndi gawo lonse Ntchito zothandizira za zotsalira za cyanide zochokera ku golide. Chaka chilichonse, polojekitiyi imapangidwa mozungulira matani a 8.000 amtundu uliwonse wa kutsogolera ndi kuyika mkuwa, matani oposa 300.000 a sulfure amaganizira, matani oposa 200.000 a sulfuric acid ndi ma pellets oxidized, pafupifupi 700 kg ya golide, ndi matailosi oposa 90 miliyoni a ku Ulaya. Zikuoneka kuti ntchitoyi yathandiza kwambiri pa zachuma, zachilengedwe komanso zathandiza anthu ambiri.
