Indima yeSodium Cyanide kwiMigodi: Uhlalutyo olunzulu

I-Sodium cyanide, i-compound ebiyinxalenye ebalulekileyo kwiShishini leMigodi kangangeminyaka engaphezu kwekhulu, idlala indima ebalulekileyo ekukhutshweni kweentsimbi ezixabisekileyo, ngakumbi igolide nesilivere. Eli nqaku liza kujonga kwiipropati zeekhemikhali ze- Sodium Cyanide , ukusetyenziswa kwayo kwemigodi, kunye nezinto ezichaphazela okusingqongileyo kunye nokhuseleko oluhambelana nokusetyenziswa kwayo.

Ukuqonda iSodium Cyanide

I-sodium cyanide (NaCN) yityuwa enyibilikayo kakhulu ene-cyanide ion (CN⁻). I-Cyanide ngokwayo yikhemikhali eyenzeka ngokwemvelo efumaneka kwiintlobo ezahlukeneyo zokusingqongileyo, kubandakanywa kwiziqhamo ezithile, amandongomane kunye nezityalo. Nangona ihlala idibaniswa nobutyhefu, kubalulekile ukuba uqaphele ukuba i-cyanide ikhona kwiindawo eziphantsi kwizinto ezininzi zemihla ngemihla, ezifana netyuwa yetafile kunye neemveliso ezithile zokutya ezifana ne-cassava kunye neziqhamo zamatye.

Kwicandelo lemizi-mveliso, i-sodium cyanide iveliswa ngobuninzi, kwaye isetyenziswa ngaphezulu kwesigidi seetoni minyaka le kwiindlela ezahlukeneyo zokusetyenziswa, kubandakanya i-Electroplating , i-Metalworking , kunye nokuveliswa kweekhemikhali ze-organic kunye neeplastiki. Nangona kunjalo, eyona ndlela ibalulekileyo yokusebenza kwayo isekwishishini lezemigodi, apho isetyenziselwa ukukhupha igolide nesilivere kwi-ore.

Inkqubo yeMigodi: Isebenza njani iSodium Cyanide

Inkqubo yokukhupha igolide kwi-ore kusetyenziswa i-sodium cyanide yaziwa ngokuba yi -Cyanide Leaching okanye i-cyanidation. Le ndlela ibisetyenziswa lishishini lezemigodi kangangeminyaka engaphezu kwe-120 kwaye isebenza kakhulu ngenxa yokukwazi kwayo ukunyibilikisa amasuntswana egolide nesilivere kwilitye elijikelezileyo.

1. Ukutyumza nokuGcoba: Inyathelo lokuqala kwinkqubo yokutyumza i-cyanidation libandakanya ukutyumza nokucola i-ore ukuze kukhutshwe amasuntswana egolide. Le nkqubo ebonakalayo yonyusa indawo yomphezulu we-ore, ivumela ukuba kubekho ii-chemical reactions ezisebenzayo ngakumbi.

2. Ukulungiswa kwesisombululo seCyanide: Nje ukuba i-ore icoliwe kakuhle, ixutywa nesisombululo esinyibilikisiweyo se-sodium cyanide, ngokuqhelekileyo kwiingqinisiso eziqala kwi-0.01% ukuya kwi-0.05%. Isisombululo se-cyanide emva koko singeniswa kwi-ore kwi-leaching tank.

3. Ukuhluza: Ngexesha lenkqubo yokuhluza, i-sodium cyanide idibana negolide nesilivere kwi-ore, yenze i-complex enyibilikayo. Oku kuvumela ukuba izinyithi ezixabisekileyo zahlulwe kwizinto ezilahliweyo. Inkqubo yokuhluza ingathatha iiyure ezininzi ukuya kwiintsuku, kuxhomekeke kuhlobo lwe-ore kunye noxinzelelo lwe-cyanide esetyenzisiweyo.

4. Ulawulo lwe-pH: Ukuthintela ukwakheka kwegesi ye-hydrogen cyanide enobuthi (HCN), i-pH ye-slurry ijongwa ngononophelo kwaye ihlengahlengiswa. Ilayimu okanye ezinye izinto ze-alkaline zongezwa ukugcina inqanaba le-pH eligcina ii-ion ze-cyanide zizinzile kwaye zingenabungozi.

5. Ukufunyanwa kweGolide: Emva kwenkqubo yokuhluza, i-gold-cyanide complex iyahlulwa kwi-slurry eseleyo. Oku kwenziwa kusetyenziswa i-activated carbon, efunxa igolide kwisisombululo. Igolide emva koko isuswa kwi-carbon kwaye ixutywe ngakumbi ngaphambi kokuba inyibilikiswe ibe ziibha zegolide.

Iingqwalasela zokusiNgqongileyo noKhuseleko

Nangona i-sodium cyanide isisixhobo esisebenzayo kwiGold Extraction , ukusetyenziswa kwayo kuphakamisa inkxalabo enkulu kwindalo nakwizokhuseleko. Ubuthi be-cyanide bubhalwe kakuhle, kwaye ukuphathwa ngendlela engafanelekanga okanye ukukhutshwa ngengozi kunokuba nemiphumo emibi kwindalo nakwimpilo yabantu.

1. Impembelelo kwiNdalo: Ishishini lemigodi liphantsi koqwalaselo olukhulu malunga nezenzo zalo kwindalo. Ukuchitheka okanye ukuvuza kwe-cyanide kunokungcolisa imithombo yomhlaba namanzi, nto leyo ebeka umngcipheko kwizilwanyana zasendle nakuluntu lwasekuhlaleni. Ngenxa yoko, amazwe amaninzi asebenzise imithetho engqongqo elawula ukusetyenziswa kunye nokulahlwa kwe-cyanide kwimisebenzi yemigodi.

2. Imigaqo yoKhuseleko: Iinkampani zemigodi kufuneka zilandele imigaqo yokhuseleko engqongqo ukunciphisa iingozi ezinxulumene nokusetyenziswa kwe-cyanide. Oku kuquka ukuqeqesha abasebenzi ngeendlela ezifanelekileyo zokuphatha, ukuphumeza izicwangciso zokuphendula ngexesha likaxakeka, kunye nokuhlola rhoqo iindawo zokugcina nokucubungula.

3. Iindlela Ezizezinye: Ukuphendula kwiinkxalabo zokusingqongileyo, ezinye iinkampani zemigodi zihlola ezinye iindlela zokukhupha igolide ezingaxhomekekanga kwi-cyanide. Ezi ndlela ziquka ukwahlulahlula amandla angaphantsi komhlaba, ukudada, kunye nokuphuma kwezinto eziphilayo, ezisebenzisa iintsholongwane ukukhupha isinyithi kwi-ore. Nangona kunjalo, ezi ndlela zisenokungasebenzi kakuhle okanye zingabizi kakhulu njenge-cyanidation.

Ikamva leSodium Cyanide kwiMigodi

Njengoko imfuno yegolide nesilivere iqhubeka ikhula, ishishini lemigodi liya kuqhubeka lixhomekeke kwi-sodium cyanide ukuze itsalwe. Nangona kunjalo, ishishini likwajongene noxinzelelo lokwamkela iindlela ezizinzileyo kunye nokunciphisa indawo ekhoyo yokusingqongileyo.

Uphando kunye neenzame zophuhliso ziyaqhubeka ukuphucula ulawulo lwecyanide kunye nokuphonononga ezinye iindlela ezikhuselekileyo. Ukwenziwa kwezinto ezintsha kuhlaziyo lwe-cyanide kunye neenkqubo zokukhupha ubutyhefu kuyaphandwa ukuze kuncitshiswe inkunkuma kunye nokunciphisa ubungozi bokwenzakaliswa kokusingqongileyo.

Ngaphezu koko, icandelo lezemigodi liya lisanda ngokwanda ukubakho elubala kunye nokuthatha uxanduva, neenkampani ezininzi ezizibophelele kwiindlela zokuthobela imigodi. Oku kuquka ukusebenzelana noluntu lwasekuhlaleni, ukwenza uhlolo lwempembelelo yokusingqongileyo, kunye nokutyala imali kubuchwepheshe obuphakamisa ukhuseleko nokuzinza.

isiphelo

Isodium cyanide ihleli iyinxalenye ebalulekileyo kushishino lwasezimayini, ingakumbi ekufumbeni igolide nesilivere kwintsimbi ekrwada. Ngelixa ukusebenza kwayo kungenakuphikiswa, okunxulumene nokusingqongileyo kunye neenkxalabo zokhuseleko zifuna ulawulo olunenkathalo kunye nokongamela. Njengoko ishishini likhula, ugqaliselo kwiindlela ezizinzileyo kunye neendlela ezizezinye zokombiwa kwemigodi ziya kudlala indima ebalulekileyo ekubumbeni ikamva lemigodi. Ngokulungelelanisa imfuno yokukhutshwa kwezixhobo kunye nokulawulwa kokusingqongileyo, ishishini lemigodi lingasebenzela ikamva elizinzileyo nelinoxanduva.
