Ukukhutshwa ngokufanelekileyo kwegolide kunye nesilivere kwi-ore yinkqubo enzima efuna ukulawulwa kweekhemikhali ezichanekileyo kunye nobuchule obuphezulu bokucubungula. Phakathi kwezinto ezininzi ezisetyenziswa kwimigodi yanamhlanje,Polyacrylamide(PAM) ibalasele njengenye yezona khemikhali zemigodi zisebenza kakhulu kwaye zisetyenziswa ngokubanzi. Ngeempawu ezibalaseleyo zokudada kunye nokuguquguquka kwiindlela ezahlukeneyo ze-ore, i-PAM idlala indima ebalulekileyo ekuphuculeni ukwahlukana, ukwandisa isivuno, kunye nokunciphisa impembelelo yokusingqongileyo kuyo yonke inkqubo yokubuyisela igolide kunye nesilivere.
Isebenza njani iPolyacrylamide kwiNkqubo yokuKhutshwa
1. Ukulungiswa kwentsimbi
Inkqubo iqala ngokutyunyuzwa nokugaya intsimbi ekrwada, apho intsimbi ekrwada iyancitshiswa ibe ngamasuntswana afanelekileyo alungele ukuvuthwa. Le intsimbi ekrwada idityaniswe namanzi kunye nekalika ukwenza udaka olufanayo kwilitye lokusila. Udaka olunesiphumo lubonelela ngesiseko semisebenzi yesinyithi esezantsi efana nentlenga, i-leaching, kunye ne-adsorption.
2. Intlenga kunye ne-Flocculation
Olu daka lungeniswa ngokulandelayo kwisitshizi sangaphambi kokuvuza. KulaphoPolyacrylamide Flocculantszongezwa kuqala. Iimolekyuli zePAM zinceda ukubopha amasuntswana aqinileyo aqinileyo kunye, okubangela ukuba zenze iiaggregates ezinkulu okanye "iiflokhi." Ezi flocs zihlala ngokukhawuleza ezantsi kwetanki etyebileyo, okukhokelela kwisigaba solwelo esicacisiweyo phezulu. Eli nyathelo liyimfuneko ekususeni izinto eziqinileyo ezigqithisileyo kunye nokuphucula ukusebenza kweenkqubo zemichiza elandelayo.
3. I-Cyanide Leaching
Emva kokwahlula okuqinileyo kolwelo, i-slurry ejiyileyo ingena kuluhlu lweetanki ezikhuphayo. Kule matanki, isisombululo se-cyanide songezwa ukunyibilikisa igolide kunye nesilivere kwi-ore. I-PAM inceda ukugcina ukuhambelana kwe-slurry kunye nokuphucula intsebenziswano phakathi kwe-cyanide kunye neengqungquthela zamaminerali. Olu qhagamshelo luphuculweyo lukhulisa ukusebenza kakuhle, oko kwenza ukuba igolide nesilivere engakumbi ibuyiselwe kwisixa esifanayo sentsimbi ekrwada ekrwada.
4. ICarbon Adsorption
Emva kokuba iintsimbi ezixabisekileyo zinyibilikisiwe kwisisombululo, i-slurry igeleza kwiitanki ze-carbon adsorption. Kweli nqanaba, ikhabhoni esebenzayo ibhengeza igolide enyityilisiweyo kunye nesilivere kwisisombululo. Ukusetyenziswa kwe-polyacrylamide kuqinisekisa ukuba i-slurry ihamba ngokulinganayo kwaye ngaphandle kokuvala, ivumela ukuxuba okungcono kunye ne-adsorption ephezulu. Okukhona olu qhagamshelwano lusebenza kakuhle, kokukhona liphezulu izinga lokubuyisela iintsimbi ezixabisekileyo.
5. Elution and Metal Recovery
Ikhabhoni elayishwe ngetsimbi iye yahlulwa kwaye idluliselwe kwinkqubo ye-elution, apho amanzi ashushu kakhulu okanye isisombululo se-cyanide se-caustic sihlutha igolide kunye nesilivere kwikhabhoni. Isisombululo esifunyenweyo, ngoku esityebileyo kwiiyoni zentsimbi, sithunyelwa kwindawo yokunyibilikisa ukuze sicocwe ngakumbi. I-slurry eseleyo-edla ngokubizwa ngokuba yi-tailings-idluliselwa kwi-tailing pods. Apha, i-PAM iphinda isetyenziselwe ukuhlalisa i-solids eseleyo, ukucacisa amanzi, kunye nokuxhasa ukugcinwa okukhuselekileyo, uxanduva lokusingqongileyo kwinkunkuma yemigodi.
Izinto eziluncedo zokuSebenzisa iPolyacrylamide kwiMigodi yeGolide
✅ Izivuno zokuCinywa okuPhezulu
I-Polyacrylamide flocculants inokonyusa amazinga egolide kunye nesilivere ngaphezulu kwe-20%, ngokwezifundo zokuphucula inkqubo yemigodi. Ukwahlula okuphuculweyo kukhokelela kwimveliso enkulu yesinyithi kunye nokusetyenziswa ngcono kwemithombo ye-ore.
✅ Ixesha loLungiso oluKhawulezayo
Ngokukhawulezisa i-sedimentation kunye nokuphucula ukuhamba kwe-slurry, i-PAM inceda ukunciphisa ixesha lokugcinwa kwi-thickeners kunye namatanki. Oku kunokukhokelela kwi-30% yokucubungula ngokukhawuleza, ukuphucula i-output kunye nokunciphisa ixesha lokusebenza.
✅ Ixabisa kakhulu kwaye iZinzile
Ukusetyenziswa kwePolyacrylamide kunceda ukunciphisa inani le-cyanide kunye nezinye ii-reagents ezifunekayo, ukunciphisa iindleko zemichiza. Ukongeza, ukusetyenzwa kwakhona kwamanzi okuphuculweyo kunye nokukhutshwa kweekhemikhali ezisezantsi kunegalelo kwimisebenzi yemigodi egcinakeleyo yokusingqongileyo, ukunceda imisebenzi ukuba ihlangabezane nemigaqo karhulumente kunye nemigangatho yokusingqongileyo.
Umboneleli othembekileyo wePolyacrylamide kwizicelo zeMigodi
Njengengcaliumthengisi weekhemikhali zokunyanga amanzikunye neekhemikhali zemigodi, sibonelela ngoluhlu olupheleleyo lweemveliso ze-polyacrylamide ezifanelekileyo kwi-ore yegolide nesilivere. Nokuba ufuna i-anionic, i-cationic, okanye i-PAM engeyiyo ionic, siyabonelela:
- Ukucoceka okuphezulu kunye nomgangatho ongaguqukiyo
- Inkxaso yobuchwephesha kwidosi kunye nokulungiswa kwesicelo
- Ukupakishwa ngokwezifiso kunye nokuhanjiswa okukhulu
- Amaxabiso akhuphisanayo kunye nokuthunyelwa ngokukhawuleza
Sikwasebenzisa iilabhoratri eziphambili kwaye sigcina ulawulo olungqongqo lomgangatho ukuqinisekisa ukuba yonke ibhetshi ihlangabezana neemfuno zakho zokusetyenzwa.
