Ukusetshenziswa kwe-Polyacrylamide ekukhishweni kwegolide nesiliva

Ukukhishwa kwegolide nesiliva ngendlela ephumelelayo kuyinqubo eyinkimbinkimbi edinga ukulawulwa kwamakhemikhali okunembile kanye namasu okucubungula athuthukile. Phakathi kwezinto eziningi ezisetshenziswa ezimayini zesimanje,I-Polyacrylamide(PAM) ivelele njengenye yamakhemikhali okumba asebenza kahle futhi asetshenziswa kabanzi. Njengoba inezakhiwo ezinhle kakhulu zokucwilisa kanye nokuzivumelanisa nezimo zezinhlobo ezahlukene ze-ore, i-PAM idlala indima ebalulekile ekuthuthukiseni ukuhlukaniswa, ukwandisa isivuno, kanye nokunciphisa umthelela emvelweni kuyo yonke inqubo yokubuyisa igolide nesiliva.

Indlela I-Polyacrylamide Esebenza Ngayo Enqubweni Yokukhipha

1. Ukulungiselela i-Ore

Inqubo iqala ngokuchoboza nokugaya i-ore, lapho i-ore eluhlaza incishiswa ibe usayizi wezinhlayiya ezincane ezifanele ukukhucululwa. Le ore echotshoziwe ibe isixutshwa namanzi kanye ne-lime ukuze kudalwe i-slurry efanayo emshinini wokugaya ibhola. I-slurry ephumelayo ihlinzeka ngesisekelo semisebenzi yensimbi engezansi njengokufakwa kwe-sedimentation, ukukhucululwa, kanye nokumuncwa.

2. Ukuthuthwa kwendle kanye nokukhukhuleka kwenhlabathi

I-slurry ifakwa ku-pre-leach thickener. Yilapho-keAma-flocculants e-Polyacrylamidekuqala kwenezelwa. Ama-molecule e-PAM asiza ukubopha izinhlayiya ezincane eziqinile ndawonye, ​​okubangela ukuthi zakhe ama-aggregate amakhulu noma “ama-floc.” La ma-floc ahlala ngokushesha phansi kwethangi lokujiya, okuholela esigabeni soketshezi esicacile phezulu. Lesi sinyathelo sibalulekile ekususeni izinto eziqinile ngokweqile kanye nokuthuthukisa ukusebenza kahle kwezinqubo zamakhemikhali ezilandelayo.

3. Ukuhlanzwa kwe-Cyanide

Ngemva kokuhlukaniswa koketshezi oluqinile, udaka olujiyile lungena ochungechungeni lwamathangi okukhipha amanzi. Kula matanki, kunezelwa isisombululo se-cyanide ukuze kuncibilikiswe igolide nesiliva kusuka ku-ore. I-PAM isiza ukugcina ukuhambisana okuhle kokudaka kwamanzi futhi ithuthukise ukusebenzisana phakathi kwe-cyanide nezinhlayiya zamaminerali. Lokhu kuxhumana okuthuthukisiwe kukhulisa ukusebenza kahle kokukhipha amanzi, okwenza igolide nesiliva eliningi litholakale enanini elifanayo le-ore eluhlaza.

4. Ukumuncwa Kwekhabhoni

Uma izinsimbi eziyigugu sezincibilikisiwe esixazululweni, i-slurry igeleza ematangini okumunca i-carbon. Kulesi sigaba, i-activated carbon imunca igolide nesiliva elincibilikisiwe esixazululweni. Ukusetshenziswa kwe-polyacrylamide kuqinisekisa ukuthi i-slurry igeleza ngokulinganayo futhi ngaphandle kokuvaleka, okuvumela ukuxubana okungcono kanye nokumunca okuphezulu. Uma lokhu kuxhumana kusebenza kahle, izinga lokubuyisa lezinsimbi eziyigugu liyanda.

5. Ukulungiswa Nokubuyiselwa Kwensimbi

Ikhabhoni egcwele insimbi iyahlukaniswa bese idluliselwa ohlelweni lokuhlanza, lapho amanzi ashisayo kakhulu noma isixazululo se-caustic cyanide sisusa igolide nesiliva kukhabhoni. Isixazululo esitholiwe, manje esicebile ngama-ion ensimbi, sithunyelwa esikhungweni sokuncibilikisa ukuze sihlungwe kabanzi. I-slurry esele—evame ukubizwa ngokuthi ama-tailings—idluliselwa emachibini ama-tailings. Lapha, i-PAM isetshenziswa futhi ukuxazulula izinto ezisele eziqinile, ukucacisa amanzi, nokusekela ukugcinwa kwemfucuza yezimayini okuphephile nokunesibopho semvelo.

Izinzuzo Zokusebenzisa i-Polyacrylamide Ekumbeni Igolide

✅ Isivuno Esiphezulu Sokukhipha

Ama-flocculant e-Polyacrylamide angakhuphula amazinga okubuyisa igolide nesiliva ngaphezu kuka-20%, ngokusho kwezifundo zokuthuthukisa inqubo yokumba. Ukusebenza kahle kokuhlukaniswa okuthuthukisiwe kuholela ekukhiqizweni okukhulu kwensimbi kanye nokusetshenziswa okungcono kwezinsizakusebenza ze-ore.

✅ Isikhathi Sokucubungula Esisheshayo

Ngokusheshisa ukuthuthwa kwenhlabathi kanye nokuthuthukisa ukugeleza kwe-slurry, i-PAM isiza ukunciphisa isikhathi sokugcina izinto eziqinile nasemathangini. Lokhu kungaholela ekucutshungulweni okusheshayo okungafika ku-30%, kuthuthukiswe ukwenziwa kwe-output kanye nokunciphisa isikhathi sokungasebenzi.

✅ Isebenza Kahle Futhi Ihlala Isikhathi Eside

Ukusetshenziswa kwe-Polyacrylamide kusiza ukunciphisa inani le-cyanide nezinye izinto ezidingekayo, kunciphisa izindleko zamakhemikhali. Ngaphezu kwalokho, ukuvuselelwa kwamanzi okuthuthukisiwe kanye nokukhishwa kwamakhemikhali okuphansi kunegalelo emikhubeni yokumba eqhubekayo ngokwemvelo, kusiza imisebenzi ukuhlangabezana nemithetho kahulumeni kanye nezindinganiso zemvelo.

Umhlinzeki Othembekile wePolyacrylamide Wezicelo Zokumbiwa Kwezimayini

Njengochwephesheumhlinzeki wamakhemikhali okwelapha amanzikanye namakhemikhali okumba, sinikeza uhla oluphelele lwemikhiqizo ye-polyacrylamide efanelekile ekukhishweni kwegolide nesiliva. Kungakhathaliseki ukuthi udinga i-anionic, i-cationic, noma i-non-ionic PAM, sinikeza:

• Ubumsulwa obuphezulu kanye nekhwalithi ehambisanayo
• Usekelo lobuchwepheshe lomthamo kanye nokwenza ngcono ukusetshenziswa
• Ukupakishwa ngokwezifiso kanye nokulethwa ngobuningi
• Amanani okuncintisana kanye nokuthunyelwa okusheshayo

Siphinde sisebenzise amalabhorethri athuthukile futhi sigcina ukulawula okuqinile kwekhwalithi ukuqinisekisa ukuthi yonke inqwaba ihlangabezana nezidingo zakho ezithile zokucubungula.
