Yini okudingeka yenziwe ukuhlolwa kwe-leaking yegolide?

1. Ukugaya ukuhlolwa kobuciko

Ukuhlukaniswa kwe-monomer yegolide noma indawo eveziwe yegolide kuyisimo esidingekayo sokuvutha kwama-cyanide noma i-neaching entsha engeyona ingozi. Ngakho-ke, ukwandisa ngokufanelekileyo lokugaya kwembukayo kungakhulisa izinga lokuvutha. Kodwa-ke, ukugaya ngokweqile akugcini nje njengokukhulisa izindleko zokugaya, kepha futhi kwandisa amathuba okungcola okukhokhiswayo okufaka i-leach solution, okuholela ekulahlekelweni kwe-ejenti ye-cyanide noma igolide elincibilikisiwe. Ukuze ukhethe ubuciko obufanele bokugaya, ukuhlolwa kokugaya okukhulayo kumele kwenziwe kuqala.

2. Ukuhlolwa kokukhethwa kwe-ejenti ye-ejenti

I-Gold Mininess Leaching idinga ukuhlolwa kokukhethwa kwe-ejenti ye-ejenti. Ngokuvamile kudingekile ukuqhathanisa ama-ejenti wokuhlekisa asetshenziswa njengokusetshenziswa kwe-calcium peroxide, i-sodium hypochlorite, i-sodium peroxide, i-hydrogen peroxide, i-citric acid, njll. Inhloso ukuthola ukuthi ngabe ukusebenza kwangaphambili kuyadingeka yini.

I-calcium peroxide, i-sodium hypochlorite, ne-sodium peroxide zizinzile kakhulu futhi zisetshenziswa kabanzi nge-inorganides ye-inorganides, futhi zibe nezimpawu zokukhishwa kwe-oxygen yesikhathi eside. Bangakwazi ukukhulula kancane kancane i-oksijini ku-slurry ye-leading isikhathi eside, okuzuzisa ukuthuthukisa izinga le-leading yegolide. .

I-Hydrogen Peroxide kanye ne-citric acid anikeze umoya-mpilo okwanele ngesikhathi senqubo yokuvutha futhi yizo izimpendulo ezinkulu zomoya-mpilo. I-eon eholayo ye-Load Nitrate (Inani elifanele) lingabhubhisa ifilimu lokudlula kwegolide ngesikhathi senqubo yokuqothula, lisheshise izinga lokuchithwa kwegolide, futhi linciphise isikhathi sokuchithwa kwe-cranidation ukukhulisa izinga legolide.

3. Ukuvikelwa kwe-soda lime dosage test

Ukuze uvikele ukuqina kwesixazululo se-sodium cyanide noma i-ejenti ye-loching yegolide engabangethi I-alkalinity ingaphakathi kobubanzi obuthile. Njengoba ukuhlushwa kwe-alkali kukhuphuka, izinga lokuvutha ngegolide lihlala lingashintshiwe, futhi inani le-ejenti ye-leaching yegolide liyancipha ngokufanele. Uma i-alkality iphezulu kakhulu, izinga lokuchithwa kanye nezinga lokufuya kwegolide kuzokwehla esikhundleni salokho. Ngalesi sizathu, kuyadingeka ukuthola umthamo ofanele wokuvikela i-alkali nenani le-slurry ph. I-Lime, etholwa kabanzi futhi eshibhile, ivame ukusetshenziswa njenge-alkali evikela i-alkali ekuhlolweni nasekukhiqizweni. Ukuze unqume ukusetshenziswa kwayo okuqondile futhi unikeze umhlahlandlela wokukhiqizwa kwangempela.

Enqubweni ye-leashing yegolide, umthamo we-ejenti ye-Gold Leaching ulingana ngqo nezinga le-leashing yegolide ngaphakathi kwebanga elithile. Kodwa-ke, lapho umthamo we-ejenti ye-Gold Leading ephakeme kakhulu, ngeke kunyuse izindleko zokukhiqiza kuphela, kepha futhi nezinga le-leading yegolide ngeke lishintshe okuningi. Ngalesi sizathu, ngokususelwa ekuhlolweni kobuciko bokugaya, ukuze uphinde unciphise umthamo we-ejenti ye-leaching yegolide kanye nezindleko zokukhiqiza izimali, ukuhlolwa komthamo we-agent legolide.

I-5. Ukuhlolwa kwesikhathi sokuvutha

Ukuze uzuze isilinganiso esiphakeme se-leashing ngesikhathi senqubo yokuvutha, isikhathi sokufundisa singanwetshwa ukuze sichithe ngokuphelele izinhlayiya zegolide ukukhulisa izinga lokuvutha. Njengoba isikhathi sokufundisa sinwetshiwe, isilinganiso se-learting segolide sanda kancane kancane futhi ekugcineni sifinyelela inani elizinzile. Kodwa-ke, uma isikhathi sokufundisa side kakhulu, okunye ukungcola ku-slurry kuzoqhubeka nokuncibilikisa futhi kuqoqwe, kuvimbela ukuchithwa kwegolide. Ukunquma isikhathi esifanelekile sokufundisa, yenza isivivinyo sesikhathi sokufundisa.

6. I-Slurry Concentration Test

Ngesikhathi sokufuya, ukugcwala kwe-slurry kuzothinta ngqo izinga lokuvutha kanye nezinga le-leading yegolide. Lapho kukhulu ukugxila, kukhula okukhulu kakhulu kwe-flurrity ye-slurry nempofu, kwehlisa izinga lokuvutha nokukala kwegolide. Lapho ukugxila kwe-slurry kuphansi kakhulu, yize ijubane le-leading yegolide liphezulu, ivolumu yempahla kanye nokutshalwa kwezinsizakusebenza kuzokwandiswa, futhi umthamo wama-ejenti we-leading wegolide nawo nawo izindleko zokukhiqiza ezandiswa ngokulinganayo. Ukuze banqume ukugxila okuqinile kwe-leaching slurry, kwaqhutshwa ukuhlolwa kwe-slurry slurry.

7. Kusebenze ukuguqulwa kwekhabhoni

Ngendlela ye-carbon leading, ikhabhoni esebenza kanzima futhi egqoke ukugqoka kufanele isetshenziselwe ukuvikela ikhabhoni eyakhiwe kahle ekungeneni kwezinsalela zokuvuselela ngenxa yokugqoka ngesikhathi senqubo yokuvuselela kanye ne-leading, kunciphisa izinga lokuthola igolide. Ukuhlolwa ngokuvamile kusetshenziswa i-Coconut Shell kusebenze ikhabhoni, ngohlobo lwezinhlamvu eziyizinhlayiya eziyi-6 kuye kwangama-40. Ukuqothuka kwekhabhoni kusebenze, izimo yilezi: Amanzi: I-Carbon = 5: 1, evusa amahora ama-4, isivinini esishukumisayo 1700 RPM. Ngemuva kokuvusa amahora ama-4, ikhabhoni eyenziwe yagcwaliswa nge-6-mesh kanye nama-16-mesh sight. Susa izinhlayiya ezinhle zekhabhoni ngaphansi kwesihlungo. Lokho wukuthi, ikhabhoni eyenziwe yasebenza ngosayizi wezinhlayiyana eziyi-6 kuye kwayi-16 Mesh ikhethwe ngokuhlolwa kwekhabhoni kanye nokuhlolwa kwekhabhoni adsorption.

8. Ukuhlolwa okuphezulu kwekhabhoni

Ezivivinyweni ze-Gold Minising Leashing, ngokuvamile zizimisele ukusebenzisa i-Coconut Shell icushiwe ikhabhoni ngosayizi wezinhlayiya eziyizinhlayiya eziyi-6-16 ku-adcerb bese ululama negolide elincibilikisiwe. Ngemuva kokuthi kukhiqizwe ikhabhoni elayishwe igolide, ikhabhoni evuthiwe eyenziwe isetshenziselwa ukuhlaziya nokukhetha igolide eliqediwe. Ubuningi bamakhabhoni aphansi buthinta ngqo isilinganiso se-carbon adsorption. Ukuze ukhethe inqwaba efanelekile yekhabhoni, kuzokwenziwa ukuhlolwa okuphezulu kwekhabhoni.

9. Ukuhlolwa Kwesikhathi Sekhabhoni Adsorption

Ukuze unqume isikhathi esifanelekile se-carbon seaching (carbon adsorption) futhi unciphise ukugqokwa kwekhabhoni elayishwe ngegolide, ngemuva kokunquma isikhathi esiphelele sokufundela, kuyadingeka ukwenza izivivinyo zesikhathi sangaphambi kwe-carbon.

10. Ukuhlolwa okuhambisanayo ngezimo eziphelele zenqubo ye-carbon leaching

Ukuze uqinisekise ukuqina kokuhlolwa kwe-carbon leashing kanye nokuphindaphindwa kwemiphumela yokuhlola, kuyadingeka ukwenza isivivinyo esibanzi sokuhlola isimo senqubo yonke yokuhlolwa kwe-carbon leaching. Lokho wukuthi, ngemuva kokunquma izivivinyo zesimo esingenhla 9 ezinemininingwane, kuyadingeka ukwenza izimo ezinhle kakhulu zokuhlolwa kwesimo ngasinye sokugcina. Ukuhlolwa kokuqinisekisa okuphelele.
