Uthelekiso phakathi kweSodium Cyanide kunye nee-Eco-friendly Leaching Agents ngo-2026

1. Imvelaphi yoShishino ngo-2026

Itekhnoloji yokukhupha igolide ngo-2026 imi kwindawo edibanisa izinto ezimbini ukuvuthwa kwemizi-mveliso kwaye utshintsho kokusingqongileyo. Isodium i-cyanide (NaCN) iseyeyona isetyenziswa kakhulu I-reagent yokuNyusa iGolide kwihlabathi liphela ngenxa yokusebenza kwayo ngobuchule obungenakuthelekiswa nanto kunye neenzuzo zoqoqosho. Kwangaxeshanye, ii-arhente zokukhupha amanzi ezinobuhlobo nokusingqongileyo, ezidla ngokuthengiswa njenge-"cyanide-free" okanye "green leaching agents," ziyaqhubeka nokutsala ingqalelo phantsi kwemithetho yokusingqongileyo ekhulayo kunye neenkqubo-sikhokelo zotyalo-mali eziqhutywa yi-ESG.

Endaweni yobudlelwane obulula bokutshintsha indawo, inyani yangoku kushishino ibonisa ukuhlalisana kunye nokwahlulwahlulwa Phakathi Isodium cyanide kunye neenkqubo zokukhupha i-leaching ezizezinye, nganye isebenzela iintlobo ezahlukeneyo ze-ore, iimeko zomthetho, kunye neenjongo zokusebenza.

2. Imigaqo yeKhemikhali kunye neTekhnoloji

2.1 Indlela yokuNyusa iSodium Cyanide

I-sodium cyanide inyibilikisa igolide ngokusebenzisa i-Elsner reaction eqinisekisiweyo:

4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH

Iimpawu zobugcisa eziphambili:

• Ukukhetha okuphezulu kwegolide nesilivere

2.2 Iindlela zeearhente zokuNciphisa iiNgcambu ezinobuhlobo nokusingqongileyo

Iiarhente zokuleyisha ezinobuhlobo nokusingqongileyo ziquka iinkqubo ezisekelwe kwi-thiosulfate, iinkqubo ezisekelwe kwi-glycine, iinkqubo ze-chloride, kunye nee-reagents ezidityanisiweyo. Iindlela zazo ziyahluka, kodwa ngokubanzi zixhomekeke koku kulandelayo:

• Ukudibanisa igolide phantsi kweemeko ezithambileyo ze-alkaline okanye ezingathathi cala

• Ukunciphisa ubuthi obuqatha xa kuthelekiswa ne-cyanide

• Ikhemistri ye-reagent eyinkimbinkimbi ngakumbi kunye novakalelo lwenkqubo

Nangona zinomtsalane ngokwengcinga, iinkqubo ezininzi ezinobuhlobo nendalo azinazo iimodeli zoshishino ezisemgangathweni kwiindawo ezahlukeneyo ze-ore.

3. Ukusebenza kakuhle kokukhupha amanzi kunye namazinga okubuyisela

In 2026, sodium cyanide ihlala ingumlinganiselo we imisebenzi emikhulu neyokubuyisela kwimeko yesiqhelo, ingakumbi kwi-ore ezikumgangatho ophantsi nezinganyangekiyo emva konyango lwangaphambi konyango. Ii-arhente ezinobuhlobo nokusingqongileyo zihlala zisebenza kakuhle kwi-ore. ii-oxide ores ezikumgangatho ophezulu okanye ezilula, kodwa ukuhambelana kokubuyisela kuyahluka kakhulu.

4. Uthelekiso lweSakhiwo seendleko

Kwimisebenzi emininzi yorhwebo, iindleko zizonke zokukhupha amanzi ngokusebenzisa iiarhente ezinobuhlobo nokusingqongileyo zisekhona 20–50% ngaphezulu ngaphezu Isodium cyanide xa kuvavanywa ngokwe-ounce yegolide.

5. Iingqwalasela zokusiNgqongileyo noKhuseleko

Isodium cyanide

• Ubuthi obuphezulu obubukhali

• Iimfuneko ezingqongqo zokuphatha, ukuthuthwa, kunye nokukhupha ubuthi emzimbeni

• Iinkqubo zokutshabalalisa ezisekwe kakuhle (INCO, SO₂/Air, H₂O₂)

• Izikhokelo zokuthobela eziqinisekisiweyo phantsi kweKhowudi yoLawulo lweCyanide yaMazwe ngaMazwe

Iiarhente zokuNciphisa Ukungcola ezinobuhlobo nokusingqongileyo

• Ubuthi obuphantsi obubukhali

• Ukuncipha kokuqonda umngcipheko woluntu

• Ukususwa kwetyhefu kusafuneka kwiimveliso ezithile

Kubaluleke kakhulu, umgangatho wolawulo lomngcipheko, endaweni yokukhetha i-reagent kuphela, kumisela ukusebenza kokwenyani kwendalo.

6. Ukwamkelwa Kwemithetho kunye Neendlela Ze-ESG

Ngu-2026:

• I-sodium cyanide isavunyelwe ngokusemthethweni kwiindawo ezininzi zemigodi phantsi kweemeko ezilawulwayo

• Ukuvalwa okungaphelelanga kukho kwimimandla emincinci (umz., amazwe akhethiweyo e-EU)

• Uxinzelelo lwe-ESG lukhuthaza uvavanyo lwee-reagents ezizezinye, ingakumbi kwiiprojekthi ezintsha

Nangona kunjalo, uninzi lweemigodi ezinkulu ziyaqhubeka nokuxhomekeka kwi-sodium cyanide ngenxa ukucaca kwemithetho, i-inshorensi, kunye nokukwazi ukubhenka.

7. Imizekelo yokusetyenziswa ngo-2026

I-Sodium Cyanide ikhethwa xa:

• Ukucubungula iitoni ezinkulu, ii-ore ezikumgangatho ophantsi

• Kufuneka ukubuyiselwa okuphezulu kunye nemveliso ezinzileyo

• Imisebenzi emincinci okanye yovavanyo lwenziwa

• Uxinzelelo lwelayisenisi yoluntu okanye yoluntu luphezulu

• Iimpawu ze-ore zikhetha ikhemistri eyahlukileyo

8. Umbono wekamva

Ngowama-2026, iiarhente zokukhupha amanzi ezinobuhlobo nokusingqongileyo ziya ayilonto ithatha indawo yendalo yonke kwi-sodium cyanide kodwa isebenza njenge izongezo zeqhinga kwiimeko ezithile. I-Sodium cyanide isengumgangatho wezoshishino wokuhluza igolide, ngelixa ii-reagents eziluhlaza ziqhubeka nokuguquka ngokusetyenziswa okujoliswe kuko, ukuphuculwa kwetekhnoloji, kunye nokuhlanganiswa kwenkqubo ye-hybrid.

Ikamva lokuhluza igolide alikho ekukhetheni amacala, kodwa likwi ukuphuculwa kwenkqubo, ulawulo lomngcipheko, kunye nokukhetha i-reagent ethile.

9. Isiphelo

Ii-sodium cyanide kunye nee-agents ezikhupha igolide ezihambelanayo nendalo zimele iindlela ezimbini ezihambelanayo kwi-metallurgy yanamhlanje yegolide. I-sodium cyanide inika ukusebenza kakuhle okungenakuthelekiswa nanto, ukwandiswa, kunye nokuzinza kwezoqoqosho, ngelixa ii-agents ezikhupha igolide ezihambelana nendalo zijongana nemithetho, intlalo, kunye neemeko ezingqongileyo kwizicelo ze-niche.

Ngowama-2026, abaqhubi abanolwazi ababuzi "Yeyiphi i-reagent engcono?"
Bayabuza "Yeyiphi i-reagent efanelekileyo kule ore, kule ngingqi, nakule projekthi?"
