Ukukhishwa okuphumelelayo kwegolide nesiliva ku-ore kuyinqubo eyinkimbinkimbi edinga ukulawulwa kwamakhemikhali okunembayo kanye namasu okucubungula athuthukile. Phakathi kwama-reagents amaningi asetshenziswa ezimayini zanamuhla,I-Polyacrylamide(PAM) igqama njengenye yamakhemikhali ezimayini asebenza kahle futhi asetshenziswa kabanzi. Ngezakhiwo ezinhle kakhulu zokuntanta nokuvumelana nezimo ezihlukahlukene ze-ore, i-PAM idlala indima ebalulekile ekuthuthukiseni ukuhlukana, ukwandisa isivuno, kanye nokunciphisa umthelela wendawo yonke inqubo yokuthola igolide nesiliva.
Isebenza kanjani i-Polyacrylamide kunqubo yokukhipha
1. Ukulungiselela Insimbi
Inqubo iqala ngokuchotshozwa nokugaywa kwensimbi, lapho insimbi eluhlaza iyancipha ibe usayizi wezinhlayiyana ezincane ezifanele ukucwiliswa. Le nsimbi egayiwe ibe isixutshwa namanzi kanye nomcako ukuze kwakhiwe udaka olufanayo emshinini wokugaya ibhola. I-slurry ewumphumela ihlinzeka ngesisekelo semisebenzi yensimbi ephansi njengomfula, i-leaching, kanye ne-adsorption.
2. I-Sedimentation kanye ne-Flocculation
Ngokulandelayo i-slurry yethulwa ku-thiener yangaphambi kokuvuza. Lapha kulaphoI-Polyacrylamide Flocculantszengezwa kuqala. Ama-molecule e-PAM asiza ukuhlanganisa izinhlayiya eziqinile eziqinile, azenze zakhe ama-aggregate amakhulu noma “ama-flocs.” Lawa ma-flocs ahlala ngokushesha ngaphansi kwethangi elijiyile, okuholela esigabeni esicacile soketshezi phezulu. Lesi sinyathelo sibalulekile ekususeni okuqinile okweqile kanye nokwenza ngcono ukusebenza kwezinqubo zamakhemikhali ezilandelayo.
3. I-Cyanide Leaching
Ngemuva kokuhlukaniswa okuqinile-oketshezi, i-slurry eqinisiwe ingena ochungechungeni lwamathangi agelezayo. Kulawa mathangi, kunesixazululo se-cyanide ukuze kuncibilike igolide nesiliva ensimbini. I-PAM isiza ukugcina ukungaguquguquki okuhle kwe-slurry futhi ithuthukise ukusebenzisana phakathi kwezinhlayiya ze-cyanide nezamaminerali. Lokhu kuthintana okuthuthukisiwe kuthuthukisa ukusebenza kahle kwe-leaching, okwenza igolide nesiliva elengeziwe litholakale enanini elifanayo lensimbi eluhlaza.
4. Ikhabhoni Adsorption
Uma izinsimbi eziyigugu sezincibilikisiwe esixazululo, udaka lugelezela emathangeni e-carbon adsorption. Kulesi sigaba, ikhabhoni ecushiwe ikhangisa igolide nesiliva elincibilikisiwe esixazululweni. Ukusetshenziswa kwe-polyacrylamide kuqinisekisa ukuthi i-slurry igeleza ngokulinganayo futhi ngaphandle kokuvinjelwa, okuvumela ukuxuba okungcono kanye nokukhanga okukhulu. Uma lokhu kuthintana kusebenza kahle kakhulu, izinga lokutholwa kwezinsimbi ezibalulekile liyakhuphuka.
5. Elution kanye Metal Recovery
Ikhabhoni elayishwe insimbi ibe isihlukaniswa futhi idluliselwe ohlelweni lwe-elution, lapho amanzi ashisa kakhulu noma i-caustic cyanide solution ikhipha igolide nesiliva kukhabhoni. Ikhambi elitholiwe, manje elicebile ngama-ion ensimbi, lithunyelwa endaweni yokuncibilikisa ukuze liqhubeke nokucwengisiswa. Udaka olusele—oluvame ukubizwa ngokuthi ama-tailings—ludluliselwa emachibini anezinsika. Lapha, i-PAM iphinde isetshenziselwe ukulungisa izinto eziqinile ezisele, ukucacisa amanzi, nokusekela ukugcinwa okuphephile, okuhambisana nemvelo kodoti wasezimayini.
Izinzuzo Zokusebenzisa i-Polyacrylamide Emayini Yegolide
✅ Isivuno Esiphezulu Sokukhipha
Ama-Polyacrylamide flocculants angakhuphula izinga lokutholwa kwegolide nesiliva ngaphezu kuka-20%, ngokuya ngezifundo zokuthuthukisa inqubo yezimayini. Ukusebenza okuthuthukisiwe kokuhlukanisa kuholela ekukhiqizweni kwensimbi okukhulu kanye nokusetshenziswa okungcono kwemithombo yensimbi.
✅ Isikhathi Sokucubungula Esisheshayo
Ngokusheshisa ukubola nokuthuthukisa ukugeleza kwe-slurry, i-PAM isiza ukunciphisa isikhathi sokugcina kuma-thickeners namathangi. Lokhu kungaholela ekucutshungulweni okusheshayo okungafika ku-30%, ukuthuthukisa ukusebenza nokunciphisa isikhathi sokusebenza.
✅ Iyabiza futhi Ihlala njalo
Ukusetshenziswa kwe-Polyacrylamide kusiza ukunciphisa inani le-cyanide namanye ama-reagents adingekayo, ukunciphisa izindleko zamakhemikhali. Ukwengeza, ukugaywa kabusha kwamanzi okuthuthukisiwe kanye nokukhishwa kwamakhemikhali aphansi kunomthelela ezenzweni zezimayini ezisimeme imvelo, kusiza imisebenzi ukuhlangabezana nemithetho kahulumeni kanye nezindinganiso zemvelo.
Umhlinzeki Othembekile we-Polyacrylamide Yezicelo Zezimayini
Njengochwephesheumphakeli wamakhemikhali okwelapha amanzikanye namakhemikhali ezimayini, sinikeza uhla olugcwele imikhiqizo polyacrylamide efanelekayo igolide nesiliva ore isizinda. Kungakhathaliseki ukuthi udinga i-anionic, i-cationic, noma i-PAM engeyona i-ionic, sinikeza:
- Ukuhlanzeka okuphezulu kanye nekhwalithi engaguquki
- Ukwesekwa kobuchwepheshe komthamo kanye nokwenza kahle kohlelo lokusebenza
- Ukupakishwa ngokwezifiso nokulethwa kwenqwaba
- Amanani okuncintisana nokuthunyelwa okusheshayo
Siphinde sisebenzise amalabhorethri athuthukile futhi sigcina ukulawula okuqinile kwekhwalithi ukuze siqinisekise ukuthi yonke inqwaba ihlangabezana nezidingo zakho ezithile zokucubungula.
