Indima yeSodium Cyanide kwiMigodi: Uhlalutyo olunzulu

Isodium cyanide, ikhompawundi ethe yadityaniswa ne Icandelo lezemigodi ngaphezulu kwenkulungwane, idlala indima ebalulekileyo ekukhutshweni kweentsimbi ezixabisekileyo, ngakumbi igolide nesilivere. Eli nqaku lingena kwiipropati zeekhemikhali ze Isodium cyanide, izicelo zayo emigodini, kunye nokuqwalaselwa kokusingqongileyo nokhuseleko ezinxulumene 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 lezoshishino, sodium cyanide iveliswa ngobuninzi, ngaphezulu kwesigidi seetoni ezisetyenziswa minyaka le kwizicelo ezahlukeneyo, kubandakanywa I-Electroplating, U msebenzi, kunye nokuveliswa kweekhemikhali eziphilayo kunye neeplastiki. Nangona kunjalo, ukusetyenziswa kwayo okuphawulekayo kuhlala kushishino lwemigodi, apho isetyenziselwa ukukhupha igolide nesilivere kwi-ore.

Inkqubo yeMigodi: Isebenza njani iSodium Cyanide

Inkqubo yokukhupha igolide kwi-ore usebenzisa i-sodium cyanide yaziwa njenge I-Cyanide Leaching okanye i-cyanidation. Le ndlela isetyenziswe kushishino lwemigodi iminyaka engaphezu kwe-120 kwaye isebenza ngokukodwa ngenxa yokukwazi ukunyibilikisa amasuntswana egolide nesilivere asuka kwilitye elijikelezileyo.

1. Ukutyumza kunye nokuSila: Inyathelo lokuqala kwinkqubo ye-cyanidation ibandakanya ukutyumza nokusila intsimbi ekrwada ukuze kukhululwe amasuntswana egolide. Le nkqubo yomzimba yonyusa indawo engaphezulu yentsimbi ekrwada, ivumela ukusabela okusebenzayo kweekhemikhali.

2. ULungiselelo lweSicombululo seCyanide: Emva kokuba i-ore icolile, ixutywe kunye nesisombululo se-sodium cyanide, ngokuqhelekileyo kwiimpawu ezisuka kwi-0.01% ukuya kwi-0.05%. Isisombululo secyanide singeniswa kwintsimbi ekrwada ekwitanki yokuvuza.

3. Leaching: Ngethuba lenkqubo yokucoca, i-sodium cyanide iphendula kunye negolide kunye nesilivere kwi-ore, yenze i-complex e-soluble. Oku kuvumela iintsimbi ezixabisekileyo ukuba zahlulwe kwinkunkuma. Inkqubo yokukhutshwa kwamanzi inokuthatha iiyure eziliqela ukuya kwiintsuku, ngokuxhomekeke kubume bentsimbi ekrwada kunye nokuxinana kwecyanide esetyenzisiweyo.

4. Ulawulo lwe-pH: Ukuthintela ukubunjwa kwegesi enetyhefu ye-hydrogen cyanide (HCN), i-pH ye-slurry ijongwa ngononophelo kwaye ilungiswe. Ikalika okanye ezinye izinto zealkaline zongezwa ukuze kugcinwe izinga le-pH eligcina ii-ion ze-cyanide zizinzile kwaye zingenabungozi.

5. UkuBuyiswa kweGolide: Emva kwenkqubo ye-leaching, i-gold-cyanide complex ihlukaniswe kwi-slurry eseleyo. Oku kuqhele ukwenziwa kusetyenziswa ikhabhoni esebenzayo, ebhengeza igolide kwisisombululo. Igolide ke iye ikhutshwe kwikhabhoni kwaye igxininiswe ngakumbi phambi kokuba inyibilikiswe kwizivalo zegolide.

Iingqwalasela zokusiNgqongileyo noKhuseleko

Ngoxa i-sodium cyanide sisixhobo esisebenzayo Ukutsalwa kwegolide, ukusetyenziswa kwayo kuphakamisa inkxalabo ebalulekileyo yendalo kunye nokhuseleko. Ubuthi be-cyanide bubhalwe kakuhle, kwaye ukuphathwa ngokungafanelekanga okanye ukukhutshwa ngengozi kunokuba neziphumo ezibi kwi-ecosystem kunye nempilo yabantu.

1. Impembelelo yokusingqongileyo: Ishishini lemigodi liphantsi koqwalaselo olukhulayo malunga nezenzo zalo zokusingqongileyo. Ukuchitheka okanye ukuvuza kwe-cyanide kunokungcolisa umhlaba kunye nemithombo yamanzi, kubeka imingcipheko kwizilwanyana zasendle kunye noluntu lwasekuhlaleni. Ngenxa yoko, amazwe amaninzi aphumeze imigaqo engqongqo elawula ukusetyenziswa nokulahlwa kwe-cyanide kwimisebenzi yemigodi.

2. Imigaqo yoKhuseleko: Iinkampani zemigodi kufuneka zithobele imithetho engqongqo yokhuseleko ukunciphisa umngcipheko onxulumene nokusetyenziswa kwecyanide. Oku kubandakanya ukuqeqeshwa kwabasebenzi kubuchule bokuphatha obufanelekileyo, ukuphumeza izicwangciso zokusabela ngokungxamisekileyo, kunye nokuhlolwa rhoqo kweendawo zokugcina kunye nokusebenza.

3. Iindlela ezizezinye: Ukusabela kwiinkxalabo zokusingqongileyo, ezinye iinkampani zemigodi zihlola ezinye iindlela zokutsalwa kwegolide ezingaxhomekekanga kwicyanide. Ezi ndlela ziquka ukwahlukana komxhuzulane, ukuphaphatheka, kunye ne-bioleaching, esebenzisa ii-microorganisms ukukhupha isinyithi kwi-ore. Nangona kunjalo, ezi zikhetho zinokuthi zingasebenzi kakuhle okanye zingabizi 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.
