Ubuchwephesha obuPhambili bokuLahla ngokuNgenabungozi kweGold Concentrate iNtsalela yeCyanide

Inkqubo yokwenziwa kwe-cyanidation yokukhutshwa kwegolide, eqhayisa ngembali engaphezulu kweminyaka eli-100, isaqhuba kwimveliso yangoku yegolide. Ukuthandwa kwayo kubangelwa ukulula kwayo kunye nezinga eliphezulu lokubuyisela igolide. Nangona kunjalo, le nkqubo ivelisa isixa esikhulu seentsalela zegolide. Imveliso ye i-cyanide iintsalela ezivela kugxininiso lwegolide ziye zanda ngonyaka. Iinkcukacha-manani zibonisa ukuba ishishini legolide lesizwe likhupha malunga nezigidi ezingama-80 ukuya kwi-100 leetoni zeentsalela ze-cyanide ngonyaka.

Ukugcinwa kwexesha elide kwezi ntsalela zecyanide kudala iingxaki ezininzi. Okokuqala, ithatha isixa esikhulu somhlaba. Okwesibini, ityhefu kakhulu iicyanides kwiintsalela zinokukhupha iigesi eziyityhefu kwaye zenze amanzi amdaka aneasidi. Ukongeza, ii-ion ezahlukeneyo zetsimbi zinokungcolisa imizimba yamanzi ejikelezileyo kunye nomhlaba ngamanzi angaphezulu okanye amanzi aphantsi komhlaba, oko kufaka impilo yabantu emngciphekweni. Okumangalisayo kukuba, iintsalela zecyanide ezisuka kugxininiso lwegolide ziqulathe izixhobo ezixabisekileyo ezifana neCu, Pb, Zn, Fe, Au, S, kunye neSi ezisele zingaphantsi-zifunyenwe. Ke ngoko, ukwahlula ngokukhuselekileyo amacandelo anetyhefu, ukwahlula ngokufanelekileyo kunye nokubuyisela izixhobo ezixabisekileyo, kunye nokuzuza usetyenziso olukhulu lweentsalela zecyanided ziye zaba zezona ziphambili kunye nemingeni kuphando lwehlabathi.

United Chemical Co., Ltd.'s Isisombululo: Iprojekthi epheleleyo

Ukusabela kule mingeni, United Chemical Co., Ltd. uqalise “uPhando kunye nokuSetyenziswa koBuchwephesha obuPhambili bokuLahla ngokuNgenabungozi kunye noSetyenziso lweZibonelelo zeeNtsalela zeCyanide ezisuka kwiGold Concentrates”.

I-Gradient - Controlled De - cyanidation kunye noFundo lweFlotation

“UbuChwepheshe obuNtsha beGradient- Controlled De-cyanidation kunye nokuFumana ukuFaka kwakhona kweZinto eziBalulekileyo” yamkelwa ukuze ibuyise ngokupheleleyo i-Cu, Pb, kunye ne-Zn kwiintsila zegolide zecyanidation. Ngenxa yoko, kuye kwaveliswa ugxininiso lwelothe nobhedu.

I-Pyrite Interface Activation kunye neNkqubo eDityanisiweyo yokuBuyisa iIron kunye neGolide

Okulandelayo, i-"Tekhnoloji eNtsha ye-Pyrite Interface Activation kunye ne-Combined Mineral Processing and Metallurgy for Iron and Gold Recovery" yaphunyezwa. Obu bugcisa bohlule ngokufanelekileyo kwaye bubuyise i-Fe kunye ne-Si kwi-de-cyanidated flotation tailings, ivelisa i-concentrate yesulfure kunye ne-silicon ephezulu.

I-Acid ye-Sulfuric kunye ne-Iron Pellet Production

Ugxininiso lwesulfure lusetyenzisiwe ukuvelisa iasidi yesulfuric exineneyo ngokukroziswa kweoksijini. I-slag yesulfure eyosiweyo yayifakwe i-pellets. Emva koko, kwasetyenziswa i-“High-Temperature Iron-Gold Separation Technology” ukuvelisa iipeliti zentsimbi kunye nodaka lwegolide olutyetyiswe ngeCu, Pb, kunye neZn.

Phezulu-I-Silicon Tailings Recycling

“ITekhnoloji eNtsha yeSigaba-uTshintsho lweMimiselo kunye nokuPheleleyo- kweCandelo lokurisayikilisha lokuPhakamisayo-kweentsalela zezimbiwa zeSilicon” yenze ukuba kuguqulwe iintsalela zezimbiwa zesilicon eziphakamileyo ukuya kwisitayile saseYurophu esidityanisiweyo seethayile zeceramic.

Iimpumelelo kwezobuGcisa kunye noPhando

Le projekthi ijongene “nobunzima obune” obunxulunyaniswa neentsalela zecyanide ezisuka kugxininiso lwegolide: ukuqonda ngokuchanekileyo iinxalenye eziyityhefu, ukulawula nokwahlula ngokwalathiso indlela yokuziphatha, ukubuyisela amacandelo abalulekileyo, kunye nokuphinda kusetyenziswe iintsalela zezimbiwa. Yazisa indlela entsha yokufundisa ngeendlela ezahlukeneyo, ukudibanisa ukusetyenzwa kwezimbiwa, i-metallurgy, kunye nesayensi yokusingqongileyo. Uphando lwanwenwela kulo lonke ikhonkco lokusungula izinto ezintsha, ukusuka ekufumaneni izizathu zenzululwazi ukuya ekuphuhliseni itekhnoloji yolawulo kunye nokuqhuba imiboniso yobunjineli.

Ngaphambili kwezenzululwazi nobuchwepheshe, iveze ngokucwangcisiweyo iipateni zokwenzeka kwezinto eziyityhefu kwicyanide - equlethe inkunkuma eyingozi kakhulu. Kwinqanaba lesicelo, iphuhlise itekhnoloji yokuqhawula ngokukhuselekileyo kunye nokulahlwa okuzinzileyo kwezinto ezinobuthi, ukutsalwa okudityanisiweyo kwamacandelo abalulekileyo, kunye nokusetyenziswa kwexabiso eliphezulu lemithombo ye-tailings.

Iziphumo ezichukumisayo zeSicelo soShishino

Emva kokusetyenziswa kwemveliso yempumelelo yeprojekthi, izinga lokufunyanwa kweentsimbi zexabiso kwiintsalela zegolide zecyanide liye lagqitha kuma-90%. Le mpumelelo yaqonda Ukulahlwa okungenabungozi kunye necandelo elipheleleyo Ukusetyenziswa kwezixhobo iintsalela zecyanide ezivela kugxininiso lwegolide. Ngonyaka, iprojekthi yavelisa malunga ne-8.000 yeetoni nganye ye-lothe egxininise kwaye igxile kwi-copper, ngaphezulu kwe-300.000 yeetoni ze-high-concentrate yesulfure, ngaphezulu kwe-200.000 yeetoni ze-sulfuric acid egxininisiweyo kunye neepellets ezixutywe nge-oxidized, malunga ne-700 kg yegolide, kunye ne-90 yezigidi zeethayile ezidibeneyo zaseYurophu. Kuyabonakala ukuba, lo msebenzi uye wazisa iingenelo eziphawulekayo kwezoqoqosho, kwendalo nezentlalo.
