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

1. Imvelaphi yoShishino ngo-2026

Itekhnoloji yokukhupha igolide ngo-2026 imi kwindawo ephakathi kokuvuthwa kwemizi-mveliso kunye notshintsho kwindalo esingqongileyo . I-Sodium cyanide (NaCN) iseyeyona Reagent yeGold Leaching esetyenziswa kakhulu kwihlabathi liphela ngenxa yokusebenza kwayo kakuhle kobugcisa kunye neenzuzo zoqoqosho. Kwangaxeshanye, ii-arhente zokukhupha igolide ezinobuhlobo nendalo, ezihlala zithengiswa njenge "ezingena-cyanide" okanye "ii-arhente zokukhupha igolide eluhlaza," ziyaqhubeka nokutsala ingqalelo phantsi kwemithetho yokusingqongileyo ekhulayo kunye neenkqubo zotyalo-mali eziqhutywa yi-ESG.

Endaweni yobudlelwane obulula bokutshintsha, inyani yangoku kushishino ibonisa ukubakho kunye nokwahlukana phakathi kweSodium Cyanide kunye neenkqubo zokuleaching ezizezinye, nganye ikhonza iintlobo ezahlukeneyo zeore, 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:

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

Ngowama-2026, i-sodium cyanide isasele iyindlela yokulinganisa imisebenzi yokubuyisela umva okuphezulu, emikhulu , ngakumbi kwi-ores ezikumgangatho ophantsi nezinganyangekiyo emva konyango lwangaphambi konyango. Ii-arhente ezinobuhlobo nendalo zihlala zisebenza kakuhle kwi- ores ezikumgangatho ophezulu okanye ezilula ze-oxide , kodwa ukuhambelana kokubuyisela kuyahluka kakhulu.

4. Uthelekiso lweSakhiwo seendleko
