Haɗa Hannu tare da Kazakhstan don Ƙirƙirar Masana'antar Ma'adinan Zinariya

A ci gaba da bunkasuwar masana'antar hakar gwal a duniya, Kazakhstan ta mamaye wani muhimmin matsayi tare da wadataccen albarkatun hakar zinare. Yanzu, tare da cikakken sha'awa da ikhlasi, mun kawo ƙwararrun sinadarai na leaching na zinariya - sodium Cyanide, da kuma m Ayyukan fasaha, ana sa ran yin tafiya kafada da kafada da kamfanonin hakar gwal a kasar Kazakhstan tare da bude wani sabon babi na hako ma'adinan zinare tare da hakowa.

I. A cikin zurfin Bincike na Ƙa'idar Fasaha na Cire Zinare na Cyanide

The Cyanide Gold Extraction Ana amfani da tsari sosai a filin hakar ma'adinan gwal, bisa la'akari da na'urar daukar nauyin sinadarai na musamman. Yaushe sodium cyanide Maganin (NaCN) ya zo cikin hulɗa da takin gwal, jerin hadaddun abubuwa masu rikitarwa da tsari suna faruwa a hankali.

Na farko, a cikin yanayin iska, Sodium cyanide yana jurewa raunin hydrolysis a cikin ruwa don samar da ion cyanide (CN⁻). Tare da sa hannu na iskar oxygen a cikin iska, zinare yana jure wa yanayin haɓaka tare da ions cyanide. Ma'aunin halayen sinadaran shine: 4Au + 8NaCN + O₂ + 2H₂O = 4NaAu(CN)₂ + 4NaOH. A cikin wannan dauki, zinariya yana da oxidized zuwa monovalent zinariya ions (Au⁺) da kuma samar da wani barga hadaddun - sodium dicyanoaurate (NaAu(CN)₂) tare da cyanide ions, don haka sa zinariya narkar da a cikin bayani.

Na gaba, zinariyar da aka narkar da a cikin maganin yana buƙatar cirewa. Ɗaya daga cikin hanyoyin da aka fi amfani da ita shine hanyar maye gurbin foda na zinc. Lokacin da aka ƙara zinc foda (Zn) zuwa maganin da ke dauke da sodium dicyanoaurate, saboda aikin ƙarfe mai ƙarfi na zinc fiye da na zinari, abin maye gurbin yana faruwa: 2NaAu (CN) ₂ + Zn = 2Au + Na₂Zn (CN) ₄. A cikin wannan tsari, ions na zinariya a cikin maganin ana maye gurbinsu da zinc kuma suna zub da jini a cikin nau'i na zinari na asali, don haka ana samun hakar zinariya.

Wata hanyar da aka saba amfani da ita ita ce hanyar adsorption na carbon da aka kunna. Carbon da aka kunna yana da ƙaƙƙarfan yanki mai ƙayyadaddun sararin samaniya da arziƙin microporous tsarin, kuma yana da ƙarfin adsorption mai ƙarfi don ions dicyanoaurate (Au(CN)₂⁻). Lokacin da maganin da ke ɗauke da rukunin gwal ya wuce ta wurin gadon carbon da aka kunna, ana tallata rukunin gwal akan saman carbon ɗin da aka kunna. Sa'an nan kuma, ta hanyar matakai na gaba kamar desorption da electrolysis, an raba zinari daga carbon da aka kunna don samun zinari mai girma.

II. Fa'idodin Tsarin Haɗin Zinare na Cyanide a bayyane yake

1. Muhimman Fa'idodin Kuɗi

A matsayin sinadari mai mahimmanci a cikin tsarin hakar gwal na cyanide, farashin sodium cyanide yana da inganci kuma ana iya sarrafa farashinsa a cikin manyan sikelin samarwa. Wannan yana bawa kamfanonin hakar gwal damar sarrafa farashin hakowa yadda ya kamata yayin samarwa da aiki na dogon lokaci, da inganta fa'idodin tattalin arziki. Idan aka kwatanta da wasu tsada reagents da ake bukata da sauran zinariya hakar tafiyar matakai, da Ribar Kuɗi na sodium cyanide a bayyane yake, yana rage matsi na kuɗi akan kamfanoni da haɓaka gasa a kasuwa.

2. Matsanancin Ƙarfafa Haɗin Zinare

Tsarin hakar gwal na cyanide yana da ƙarfin narkar da gwal sosai kuma yana iya fitar da gwal gaba ɗaya daga tama. A karkashin yanayin da ya dace, ƙimar dawo da gwal na iya kaiwa matsayi mai girma, wanda ke nufin kamfanoni na iya samun ƙarin zinariya daga adadin ma'adinai iri ɗaya, haɓaka ƙimar amfani da albarkatu sosai da ƙirƙirar ƙarin ƙima ga kamfanoni.

3. Balagagge da Tsayayyen Tsari

Bayan shekaru na ci gaba da aiki, tsarin hakar gwal na cyanide ya zama balagagge. Tsarin aikinsa ya daidaita kuma masu fasaha za su iya sarrafa shi cikin sauƙi. Wannan yana ba wa kamfanonin hakar gwal damar yin aiki da ƙarfi da inganci yayin aikin samarwa, rage hatsarori da asarar da ke haifar da rashin kwanciyar hankali na fasaha da rage haɗarin samarwa.

4. Faɗin daidaitawa

Wannan tsari yana da kyakkyawar daidaitawa ga nau'ikan nau'ikan zinare daban-daban. Ko shi ne oxidized tama, sulfide tama ko gauraye tama, m zinariya hakar za a iya samu ta m daidaitawa sigogi sigogi. Wannan Faɗin daidaitawa yana ba da damar ma'adinan zinare tare da yanayin yanayin ƙasa daban-daban a Kazakhstan don ɗaukar tsarin hakar gwal na cyanide da ba da cikakkiyar wasa ga fa'idodin albarkatun su.

III. Rakiya Sabis na Fasaha Duk- zagaye

Kamfaninmu ya fahimci sosai cewa samfurori masu inganci sune kawai tushen haɗin gwiwa, kuma duk - sabis na fasaha shine mabuɗin don tabbatar da ingantaccen samar da masana'antar hakar gwal. Don haka, mun kafa ƙungiyar fasaha da ta ƙunshi manyan masana don ba da tallafin fasaha guda ɗaya ga kamfanonin hakar gwal a Kazakhstan.

A farkon matakin na aikin, mu fasaha tawagar za su gudanar a cikin zurfin a kan - site ilmin kasa safiyo da kuma ma'adinai bincike a cikin zinariya ma'adanin, da kuma ta amfani gwaje-gwaje, siffanta mafi dace zinariya hakar tsari tsare-tsaren ga Enterprises don tabbatar da yiwuwa da kuma high dace da aiwatar.

A lokacin aikin samarwa, ma'aikatan fasahar mu za su ba da cikakken jagorar waƙa, da sauri magance matsalolin da kamfanoni ke fuskanta a cikin gyara kayan aiki, hanyoyin aiki, da sarrafa siga. Har ila yau, za mu ba da horo na ƙwararru akai-akai don ƙwararrun ma'aikatan fasaha da aiki na kamfanoni don taimaka musu ci gaba da haɓaka matakan fasaha da ƙwarewar aiki, tabbatar da ingantaccen aiki na tsarin samarwa.

Dangane da gyaran kayan aiki daga baya, muna da ƙungiyar ƙwararrun ƙwararrun kayan aiki waɗanda za su iya ba wa masana'antu sabis kamar duba kayan aiki na yau da kullun, kiyayewa, da gyara matsala, tabbatar da cewa kayan aikin koyaushe suna cikin yanayin aiki mai kyau, tsawaita rayuwar kayan aikin, da rage farashin kula da kayan aiki na masana'antu.

Ya ku abokan sana'ar ma'adinan gwal a Kazakhstan, muna gayyatar ku da gaske don ku ba mu hadin kai. Zaɓin samfuran mu na sodium cyanide da sabis na fasaha yana nufin zabar ƙwarewa, babban inganci, da kwanciyar hankali. Bari mu nuna basirarmu a cikin filin hakar gwal, tare da samar da mafi kyawun nasarori, da ba da gudummawa ga ci gaban masana'antar hakar gwal a Kazakhstan!
