United Chemical, iTuXingSun Mining, kunye neHenan Lingbao Gold Mine Ngokudibeneyo Ukuseka uMgodi ongenaCyanide

I-Jinchan ehambelana nokusingqongileyo i-ejenti yokutshiza igolide isetyenziswe kuMgodi weGolide i-Wenyu e-Lingbao, kwiPhondo lase-Henan, ingakumbi xa kutsalwa izinto ezixabisekileyo ezifana negolide. Le projekthi inomthamo wegolide we-9 grams ngetoni nganye kunye ne- Ikhabhoni ye-inorganic umxholo we-10.94%. Olona ncedo luphezulu lwale projekthi kukuthotyelwa kwayo kokusingqongileyo, kubandakanywa nokusetyenziswa kwe-arhente ye-Jinchan eco-friendly leaching yegolide njengebambela Isodium cyanide. Le ndlela ayiqinisekisi kuphela ukusebenza kakuhle Ukutsalwa kwegolide kodwa ikwacutha impembelelo yokusingqongileyo yenkqubo yokusetyenzwa kwentsimbi ekrwada.

Xa ucolo lokusila luyi-0.074 mm, lunomxholo ongaphezulu kwe-90%, ipulp concentration ye-40%, i-lime dosage ye-3 kg/t, i-alkaline pretreatment yeeyure ezi-2, i-Jinchan eco-friendly gold leaching agent idosi ye-600 g/t, kunye nexesha lokuvuza leeyure ezingama-24. Ireyithi yokuvuza inokufikelela kwi-95.60%. Xa kuthelekiswa ne-cyanide leaching, izinga le-leaching linyuka nge-1.4%, ukusetyenziswa kwe-reagent kuncipha nge-200 g / toni, kwaye ixesha lokucoca lifinyeziwe ngaphezu kweeyure ze-12. Ngaphezu koko, ukuhlamba Uhlalutyo lwetyhefu we Jinchan intsalela eco-friendly igolide leaching agent wabonisa ukuba leaching amaxabiso ubutyhefu cyanide, ubhedu, ilothe, zinc, kunye arsenic kwi iitailings zonke ngaphakathi kwimida umgangatho wesizwe kwaye ingakhutshwa ngokuthe ngqo ngaphandle kwemfuneko detoxification.

Eyona nto iphambili kuvavanyo oluyimpumelelo lweprojekthi ye-cyanidation yekalika epheleleyo kukusetyenziswa kwe-arhente ye-Jinchan eco-friendly leaching yegolide. Le arhente ye-leaching yenzelwe ngokukodwa ukuququzelela inkqubo yokucoca kunye nokufunxa ngokuzinzileyo. I-agent ye-Jinchan leaching agent isebenzisa i-leaching yezigaba ezine kunye ne-five-stage-absorption process, iqinisekisa ukuba nangona kukho ubukho bekhabhoni ye-inorganic, umphumo wegolide awuchaphazeleki. Le yinkqubela ebalulekileyo yeprojekthi, njengoko ibonisa ukuba ezinye iindlela ezilungele i-eco-friendly zinokusebenza njengeendlela zemveli. Xa kuthelekiswa ne-cyanide leaching, izinga le-leaching lingaphucula nge-1.4%, ukusetyenziswa kwe-reagents kuncitshiswe nge-200 grams ngetoni nganye, kwaye ixesha lokucoca lifinyeziwe ngaphezu kweeyure ze-12, okubangelwa yimiphumo emihle yokucoca kunye neenzuzo ezibalulekileyo zezoqoqosho.

Ukufakwa endaweni yesodium cyanide kunye neJinchan eco-friendly eco-friendly leaching agent kubonakalisa ukuzibophelela komgodi Ukukhuselwa kwendalo. I-sodium cyanide kudala yaba ngumgangatho weshishini lokukhutshwa kwegolide, kodwa ubuthi bayo bubeka umngcipheko omkhulu kokusingqongileyo nakwimpilo yabantu. Ngokwahlukileyo, i-agent ye-Jinchan inikezela ngenye indlela ekhuselekileyo kunye nezinzileyo, eqinisekisa ukuba inkqubo yokukhutshwa kwegolide ayifiki kwindleko yokutshatyalaliswa kwemvelo. Olu tshintsho lusiya kwiinkqubo ezilungele ukuphilisana kwendalo lunceda i-ikhosistim yasekhaya kwaye lumisela umzekelo omhle kushishino lwemigodi ngokubanzi.

Iprojekthi ye-cyanidation yekalika epheleleyo kuMgodi weGolide i-Wenyu linyathelo elibalulekileyo kwinkampani yethu ekusekeni umgodi ongena-cyanide. Le projekthi igxininisa izenzo zokukhuselwa kokusingqongileyo, kusetyenziswa ubugcisa obutsha obufana ne-Jinchan eco-friendly leaching agent yegolide, ekhokelela kwiindlela ezizinzileyo nezinenkathalo zokusetyenzwa kwegolide. Umgodi weGolide we-Wenyu ubonisa ukuba izinto ezixabisekileyo ezifana negolide zinokutsalwa ngokufanelekileyo ngaphandle kokulimaza indalo, ukubeka umgangatho omtsha kwishishini. Le projekthi iyayingqina loo nto Imigodi enoxanduva izenzo kunye nolawulo lwendalo esingqongileyo zinokuhamba kunye, zivule indlela yekamva elizinzileyo kwimigodi.
