Ubuchwepheshe Obubalulekile Bokulahlwa Okungenabungozi Kwensalela Yegolide Ye-Cyanide Egxilise Kakhulu

Inqubo ye-cyanidation yokumbiwa kwegolide, eziqhenya ngomlando weminyaka engaphezu kweyi-100, isadlangile ekukhiqizweni kwezimboni zegolide zamanje. Ukuduma kwayo kuvela ekululameni kwayo kanye nezinga eliphezulu lokuthola igolide. Noma kunjalo, le nqubo ikhiqiza inqwaba yemisila yegolide. Okukhiphayo kwe i-cyanide izinsalela ezivela ekugxilweni kwegolide ziye zanda minyaka yonke. Izibalo zikhomba ukuthi imboni yegolide kazwelonke ikhipha cishe amathani ayizigidi ezingama-80 kuya kweziyi-100 ezinsalela ze-cyanide unyaka ngamunye.

Ukuqoqwa kwesikhathi eside kwalezi zinsalela ze-cyanide kudala izinkinga eziningi. Okokuqala, ithatha indawo enkulu. Okwesibili, enobuthi kakhulu ama-cyanides ezinsalela zingakhipha amagesi anobuthi futhi zenze amanzi angcolile ane-asidi. Ukwengeza, ama-ion ensimbi ahlukahlukene angangcolisa imizimba yamanzi azungezile nomhlabathi ngamanzi angaphezulu noma amanzi angaphansi komhlaba, abeke impilo yabantu engozini. Okudidayo ukuthi, izinsalela ze-cyanide ezivela ekugxilisweni kwegolide ziqukethe izinsiza ezibalulekile njenge-Cu, Pb, Zn, Fe, Au, S, kanye no-Si ezisele ngaphansi - ezitholiwe. Ngakho-ke, ukuhlukanisa ngokuphephile izakhi ezinobuthi, ukuhlukanisa ngempumelelo kanye nokubuyisela izinsiza ezibalulekile, nokuzuza ukusetshenziswa okukhulu kwemisila ye-cyanided sekuyizinto ezibalulekile nezinselele zocwaningo emhlabeni wonke.

United Chemical Isixazululo se-Co., Ltd.: Iphrojekthi Ephelele

Ukuphendula lezi zinselelo, United Chemical Co., Ltd. iqale “Ucwaningo Nokusetshenzwa Kwezobuchwepheshe Ezibalulekile Zokulahlwa Okungenangozi kanye Nokusetshenziswa Kwensiza Yezinsalela Ze-Cyanide Ezisuka Ku-Gold Concentrates”.

I-Gradient - Controlled De - cyanidation and Flotation Recovery

“Ubuchwepheshe Obusha Be-Gradient - Controlled De - cyanidation and Flotation Recovery of Valuable Elements” yamukelwe ukuze kubuyiselwe ngokuphelele i-Cu, Pb, ne-Zn emisileni yegolide ye-cyanidation. Ngenxa yalokho, kwakhiqizwa ama-lead agxilile kanye nokugxilisa ithusi.

I-Pyrite Interface Activation kanye Nokucubungula Okuhlanganisiwe Kokubuyiselwa Kwensimbi Negolide

Okulandelayo, "Ubuchwepheshe Obusha Be-Pyrite Interface Activation kanye Nokucutshungulwa Kwamaminerali Okuhlanganisiwe kanye Ne-Metallurgy Yokubuyisela Insimbi Negolide" kwaqaliswa. Lobu buchwepheshe buhlukanise kahle futhi bubuyisele u-Fe no-Si kumasisila e-de -cyanidated flotation, bukhipha ama-concentrate esibabule kanye ne-silicon tailings ephezulu.

I-Sulfuric Acid kanye ne-Iron Pellet Production

I-sulfur concentrate yayisetshenziselwa ukukhiqiza i-concentrated sulfuric acid ngokusebenzisa ubuthakathaka - ukugazinga kwe-oxygen. I-slag yesulfure eyosiwe yayifakwe i-pelletized. Kamuva, "I-High - Temperature Iron - I-Gold Separation Technology" yasetshenziswa ukuze kukhiqizwe ama-pellets ensimbi nodaka lwegolide olunothiswe nge-Cu, Pb, ne-Zn.

High - Silicon Tailings Recycling

“Ubuchwepheshe Obusha Besigaba - Umthetho Wokushintsha kanye Nokugcwele - Ukugaywa Kabusha Kwengxenye Yezinsalela Ze-Silicon Eziphakeme” kunike amandla ukuguqulwa kwezinsalela ze-silicon eziphakeme zibe amathayela e-ceramic ahlotshaniswayo wesitayela saseYurophu.

Intuthuko Yezobuchwepheshe Nocwaningo

Le phrojekthi ibhekane "nobunzima obune" obuhlobene nezinsalela ze-cyanide ezivela ekugxilweni kwegolide: ukuqonda ngokunembile izakhi ezinobuthi, ukulawula nokuhlukanisa indlela yokuziphatha kwazo, ukubuyisela izakhi ezibalulekile, kanye nokugaywa kabusha kwemisila. Yethula indlela entsha yokuhlanganisa imikhakha eyahlukene, ehlanganisa ukucubungula amaminerali, i-metallurgy, kanye nesayensi yezemvelo. Ucwaningo lwaluhlanganisa lonke uchungechunge lokusungula izinto ezintsha, kusukela ekuvumbululeni izimbangela zesayensi kuye ekuthuthukisweni kobuchwepheshe bokulawula nokwenza imibukiso yobunjiniyela.

Ngaphambili kwezesayensi nezobuchwepheshe, yembula ngokuhlelekile amaphethini okwenzeka kwezingxenye ezinobuthi ku-cyanide - equkethe imfucumfucu eyingozi kakhulu. Ezingeni lesicelo, ithuthukise ubuchwepheshe bokuhlukanisa okuphephile kanye nokulahlwa okuzinzile kwezakhi ezinobuthi, ukukhishwa okudidiyelwe kwezingxenye ezibalulekile, kanye nokusetshenziswa kwenani eliphezulu kwezinsiza zemisila.

Imiphumela Ehlaba umxhwele Yesicelo Sezimboni

Ngemuva kokusetshenziswa kwemboni yezimpumelelo zephrojekthi, izinga lokutholwa kwezinsimbi ezibalulekile ezinsalela zegolide ze-cyanide lidlule kuma-90%. Lokhu okufeziwe kufezeke Ukulahlwa okungenangozi kanye nengxenye egcwele Ukusetshenziswa kwemithombo izinsalela ze-cyanide ezivela ku-concentrate yegolide. Ngonyaka, iphrojekthi ikhiqiza amathani angaba ngu-8.000 i-lead concentrate ngayinye kanye ne-concentrate yethusi, amathani angaphezu kuka-300.000 we-high - sulfur concentrate, amathani angaphezu kuka-200.000 we-concentrated sulfuric acid nama-pellets ane-oxidized, cishe ama-700 kg egolide, kanye namathayela angaphezu kwezigidi ezingu-90 ahlangene aseYurophu. Ngokusobala, lo msebenzi uye waletha izinzuzo eziphawulekayo kwezomnotho, ezemvelo nezenhlalo.
