Kutheni iSodium Cyanide isetyenziswa kakhulu ekutsalweni kweGolide?

Kwindawo ye ukutsalwa kwegolide, sodium cyanide ime njengesiseko se-reagent, idlala indima ebalulekileyo kushishino. Kodwa yintoni eyenza ibaluleke kangaka? Makhe sihlolisise izizathu ezibangela ukusetyenziswa kwayo ngokubanzi.

1. I-Chemical Reactivity

Sodium i-cyanideUkusebenza kakuhle ekutsalweni kwegolide kungenxa yeempawu zayo ezizodwa zeekhemikhali. Igolide, ngokohlobo lwayo lwemveli, ayisebenzi kwaye ayisebenzi ngokukhawuleza kwizinto ezininzi eziqhelekileyo. Noko ke, nini Isodium cyanide ifakwe kwinkqubo yokukhutshwa, isabela ngegolide phambi kwe-oksijini kunye namanzi ukwenza i-soluble gold-cyanide compound. Le ndlela yokusabela iguqula amasuntswana egolide anganyibilikiyo abe kwimeko yokunyibilika, nto leyo evumela ukwahlulwa lula kwi-ore matrix. Esi sixhobo sokwenza iikhompawundi ezizinzileyo kunye ne-soluble ngegolide yinto ephambili ekusebenziseni ngokubanzi Isodium cyanide kwimigodi yegolide.

2. Ubuchule kunye nobunyulu

Enye yeenzuzo eziphambili zokusebenzisa i-sodium cyanide kwi-extraction yegolide kukusebenza kwayo okuphezulu. I-Cyanide leaching inokufikelela kwinqanaba eliphezulu lokubuyiswa kwegolide, kaninzi ikhupha ukuya kuma-90% okanye ngaphezulu kwegolide ekhoyo kwintsimbi ekrwada, ngokuxhomekeke kwiimpawu ze-ore. Xa kuthelekiswa nezinye iindlela zokutsalwa, ezifana I-MERCURY Ukuhlanganiswa, i-cyanide leaching isebenza ngakumbi ekukhupheni igolide kwiindidi ezininzi ze-ore, kuquka i-ore ephantsi.

Ngaphaya koko, ikhompawundi yegolide-cyanide eyenziweyo ngexesha lenkqubo yokukhutshwa kwamanzi inokuphinda iqhutywe ngakumbi ukufumana igolide esulungekileyo. Ngamanyathelo alandelayo afana nemvula ene-zinc okanye i-electrolysis, igolide inokufunyanwa kwakhona ikwimeko esulungekileyo, ihlangabezana neemfuno zomgangatho ophezulu wobucwebe, i-electronics, kunye neemarike zotyalo-mali.

3. Iindleko - ukusebenza kakuhle

Ukususela kumbono wezoqoqosho, i-sodium cyanide inikezela ngeendleko - ukusebenza kakuhle. Nangona i-sodium cyanide ngokwayo iyityhefu, imveliso yayo kunye neendleko zokuthenga zifanelekile xa kuthelekiswa nezinye iirejenti ezinokuthi zisetyenziswe ekutsalweni kwegolide. Ukongeza, inkqubo ye-cyanidation iye yasekwa kakuhle kwaye yaphuculwa kumashumi eminyaka. Iziseko ezingundoqo kunye nezixhobo ezifunekayo ekutshixeni icyanide zikumgangatho ofanayo, zinciphisa imfuno yobuchwepheshe obubiza imali eninzi, obukhethekileyo. Oku kuthetha ukuba iinkampani zemigodi zinakho ukuzuza ukukhutshwa kwegolide okusebenzayo ngexabiso eliphantsi ngokweyunithi nganye yegolide eveliswayo, oko kuyenza ibe yindlela enomtsalane kushishino lwemigodi yegolide ekhuphisana kakhulu.

4. Iziseko zophuhliso eziSekiweyo kunye nokuQheleleka

Ushishino lokwembiwa kwegolide belusebenzisa i-sodium cyanide ukwenza igolide kwisithuba esingaphezu kwenkulungwane. Ngenxa yoko, kukho isiseko esiphuhliswe kakuhle malunga nokusetyenziswa kwe-sodium cyanide. Iinkampani zemigodi zikwazi ukufikelela kwikhonkco elithembekileyo lokubonelela nge-sodium cyanide, ukusuka kwimveliso ukuya ekuthuthweni nasekugcinweni.

Ngaphaya koko, iinjineli zemigodi, amagcisa, kunye nabasebenzi baqhelene kakhulu nenkqubo ye-cyanidation. Baqeqeshelwa ukuphatha i-sodium cyanide ngokukhuselekileyo, ukusebenzisa izixhobo zokucoca, kunye nokulawula inkqubo yokukhutshwa ngokubanzi. Olu lwazi luqokelelweyo kunye nobuchule lwenza kube lula kwimisebenzi yemigodi ukuphumeza nokugcina inkqubo ye-cyanidation, ukunciphisa i-curve yokufunda kunye nobungozi obunokubakho obunxulumene nokwamkela iindlela ezintsha kunye nezingavavanywanga zokutsalwa.

5. Ukuziqhelanisa neendidi ezahlukeneyo zentsimbi ekrwada

I-sodium cyanide-esekelwe kwiindlela zokutsalwa ziguquguquka kakhulu kuluhlu olubanzi lweentlobo zegolide zentsimbi. Nokuba isimahla - intsimbi yokusila apho igolide ikhululwe ngokulula kwilitye elisingisele, okanye ore ezintsonkothileyo ezifuna ukunyangwa kwangaphambili, icyanide leaching inokulungiswa kwaye iphuculwe. Kwi-ores ephikisayo, iindlela ezinjengokuqhotsa, i-oxidation yoxinzelelo, okanye i-bio-oxidation inokudibaniswa ne-cyanide leaching ukudiliza isakhiwo se-ore kunye nokubeka igolide kwisisombululo se-cyanide, okwenza ukuba kutsalwe ngokufanelekileyo. Oku kuguquguquka kwenza i-sodium cyanide ibe yinto ekhethwayo kwiinkampani zemigodi ezijongene neediphozithi zeore ezahlukeneyo.

Nangona kunjalo, kubalulekile ukuqaphela ukuba ngelixa i-sodium cyanide ibonelela ngeenzuzo ezibalulekileyo ekutsalweni kwegolide, ukusetyenziswa kwayo kuphakamisa iinkxalabo ezinzulu zokusingqongileyo kunye nokhuseleko ngenxa yetyhefu ephezulu. Ngenxa yoko, ishishini lihlala liphanda kwaye liphuhlisa ezinye iindlela zokutsalwa kunye nokuphucula iiprothokholi zokhuseleko ukunciphisa umngcipheko onxulumene nokusetyenziswa kwe-sodium cyanide ngelixa lisahlangabezana nemfuno yegolide yehlabathi.
