Ukusetyenziswa kweSodium Cyanide kuShishino lweMetallurgical kunye nokwabelana ngamava

intshayelelo

I-sodium cyanide (NaCN), njenge-agent esebenzayo yokudibanisa kunye ne-ejenti yokucoca, idlala indima ebalulekileyo Ushishino lweMetallological. Iimpawu zayo ezizodwa zeekhemikhali zivumela ukuba zenze ii-complexes ezizinzile kunye nee-ion ezahlukeneyo zetsimbi, ngaloo ndlela zifezekise ukutsalwa, ukwahlukana kunye nokucocwa kwesinyithi. Eli nqaku liza kuhlalutya izicelo ezingundoqo ze Isodium cyanide kwintsimi ye-metallurgical kwaye ushwankathele iingongoma eziphambili zokusebenza ngokusekelwe kumava asebenzayo.

I. Usetyenziso olungundoqo lweSodium Cyanide kuShishino lweMetallurgical

1.Ukutsalwa kweGold (Inkqubo yeCyanidation yeGold Extraction)

• Siseko: Isodium cyanide idibana negolide kubukho beoksijini ukwenza izinto ezinyibilikayo zecyanide zegolide (ezifana ne [Au(CN)₂]⁻). Igolide ke ifunyanwa ngokufakwa kwikhabhoni esebenzayo okanye ngokufuduswa kwe-zinc.

• eziluncedo: Inokulungelelaniswa okunamandla kwi-ores yegolide ephantsi kunye ne-ores enzima, kwaye izinga le-leaching lingafikelela ngaphezu kwe-90%.

• ityala: Umgodi wegolide unyuse izinga lokufunyanwa kwegolide ukuya kuma-92% ngokunyusa ukuxinana kwe sodium cyanide (0.05% -0.1%) kunye nexesha leaching (24-48 iiyure).

2.Electroplating kunye neMetal Surface Treatment

• Injongo: Njengesongezo kwi I-Electroplating izisombululo, isetyenziselwa electroplating metal ezifana ubhedu, zinc, kunye nesilivere, nto leyo enokuphucula ukufana kunye nokuncamathelisa ukutyabeka.

• Ukuqapha: Ukuxinwa kwe-cyanide kufuneka kulawulwe ngokungqongqo ukuphepha intsalela egqithisileyo, enokukhokelela kungcoliseko lwendalo.

3.Ukwahlulwa kweMetal kunye nokuCocwa

• Imeko yokusetyenziswa kwesicelo: Ngokukhethekileyo khupha iintsimbi ekujoliswe kuzo (ezifana ne-nickel kunye ne-cobalt) ukusuka kwi-polymetallic ores, okanye ususe ii-ion zokungcola (ezifana nentsimbi kunye nelothe).

• Amanqaku obugcisa: Ukufezekisa ukuxutywa kwe-stepwise yesinyithi ezahlukeneyo ngokulungelelanisa ixabiso le-pH kunye nomthamo we Isodium cyanide.

II. Amava aPhambili kunye nokuPhuculwa koBugcisa ekuSetyenzisweni kweSodium Cyanide

1.Ukulawulwa kweNgqwalasela kunye neDosage

• Umgaqo wobuGcisa: Ngexesha le-leaching yegolide, i-concentration ye-sodium cyanide ngokuqhelekileyo i-0.03% -0.1%, kwaye kufuneka ilungiswe ngokweempawu ze-ore (ezifana nomxholo wekhabhoni kunye nomxholo we-sulfide).

• ityala: Umgodi wafumanisa ukuba ukusetyenziswa kwe-sodium cyanide kwanda ngokungaqhelekanga. Emva kophando, kwafunyaniswa ukuba umxholo wesulfure kwi-ore wawudlula umgangatho. Ingxaki yasonjululwa emva kokusebenzisa inkqubo yonyango lwangaphambili (i-roasting okanye i-oxidation).

2.Ukuphuculwa kweeMeko zokuLeaching

• Ixabiso le-pHUkugcina indawo yealkaline (pH 10-11) kunokuthintela ukuveliswa kwegesi yehydrogen cyanide kunye nokuphucula igesi. Leaching Efficiency ngaxeshanye.

• iqondo lobushushu: Ukufudumala okufanelekileyo (30-40 ° C) kunokukhawuleza ukusabela, kodwa ukusetyenziswa kwamandla kunye neendleko kufuneka zilinganiswe.

3.UkuKhuselwa kokuSingqongileyo kunye noLawulo loKhuseleko

• Unyango lwamanzi amdaka: Sebenzisa indlela ye-alkaline chlorination (i-sodium hypochlorite + i-sodium hydroxide) ukubola i-cyanide ukuqinisekisa ukuba ukukhutshwa kuhambelana nomgangatho (uxinzelelo lwe-CN⁻ lungaphantsi kwe-0.5 mg / L).

• UKhuseleko loKhuseleko: Ukuxhobisa ngomgca wemveliso ovalelwe ngokupheleleyo, inkqubo yokujonga ngokuzenzekelayo, kunye nesixhobo sokufafaza ngokukhawuleza. Abaqhubi kufuneka banxibe iimpahla ezikhuselayo zeekhemikhali kunye neemaski zegesi.

III. Iingxaki eziqhelekileyo kunye nezisombululo

1.Ingozi yeCyanide Poisoning

• Amanyathelo okukhusela: Jonga rhoqo ukuqina kwesixhobo kwaye ugweme ukudibana kwesisombululo se-cyanide kunye nezinto ezinobuthi (ukuthintela ukuveliswa kwegesi ye-HCN enetyhefu kakhulu).

• Unyango olungxamisekileyo: Sula ngokukhawuleza indawo yokudibanisa ulusu kunye nomthamo omkhulu wamanzi acocekileyo. Kwimeko yokungeniswa ngengozi, ixhoba kufuneka lifune unyango ngokukhawuleza kwaye lifakwe i-thiosulfate ye-sodium ukuze i-detoxification.

2.Ukuncipha kokuLuleka ngokuSebenzayo

• Izizathu ezinokubakho: Idigri ye-oxidation eyaneleyo ye-ore, ukubola kwe-sodium cyanide (ngenxa yokukhanya okanye ukushisa okuphezulu), kunye nokuphazamiseka kwee-ion zokungcola (ezifana nelothe kunye nobhedu).

• izisombululo: Yongeza i-oxidant (efana ne-hydrogen peroxide) ukukhuthaza i-oxidation ye-ore, okanye ukususa ukungcola ngokucocwa kwangaphambili.

IV. IiNdlela zekamva kunye nobuGcisa obuBunye

• Ubuchwephesha bokuLeaching obuMahala ngeCyanide: Iinkqubo eziluhlaza ezifana nendlela ye-thiourea kunye nendlela ye-bioleaching zivela ngokuthe ngcembe, ezinokuthi zinciphise ingozi yendalo.

• Ulawulo olukrelekrele: Ukujongwa kwexesha langempela kwiiparameters ezifana nokugxininiswa kwe-sodium cyanide kunye nexabiso le-pH ngokusebenzisa i-algorithms ye-AI ukufezekisa ulawulo oluchanekileyo.

isiphelo

I-sodium cyanide inokusebenza okuphezulu kunye neengozi ezinokubakho kwishishini le-metallurgical. Ukusetyenziswa okunengqiqo kuxhomekeke kuyilo lwenkqubo yezenzululwazi, ulawulo olungqongqo lokhuseleko, kunye nokwenziwa ngokutsha kobuchwepheshe obuqhubekayo. Ngokulungisa iiparamitha zokusebenza kunye nokomeleza Ukukhuselwa kwendalo imilinganiselo, ixabiso layo linganyuswa kwaye imingcipheko incitshiswe, ukukhuthaza ishishini ukuba liphuhlise ngendlela eluhlaza kunye nozinzo.
