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

I-arhente yokukhupha igolide enobuhlobo nokusingqongileyo iJinchan isetyenzisiwe kwimizi-mveliso kwiWenyu Gold Mine eLingbao, kwiPhondo laseHenan, ingakumbi ekukhupheni izinto ezixabisekileyo ezifana negolide. Le projekthi inomxholo wegolide oyi-9 grams ngetoni kunye nomxholo we -Inorganic carbon oyi-10.94%. Inzuzo enkulu yale projekthi kukuthobela kwayo indalo, kubandakanya ukusetyenziswa kwe-arhente yokukhupha igolide enobuhlobo nokusingqongileyo iJinchan endaweni yeSodium Cyanide . Le ndlela ayiqinisekisi nje kuphela ukukhutshelwa kweGolide ngokusebenza kakuhle kodwa ikwanciphisa impembelelo yenkqubo yokucubungula i-ore kwindalo.

Xa ubuncinci bokugaywa buyi--0.074 mm, kunye nomxholo ongaphezulu kwe-90%, uxinaniso lwepulp lwe-40%, idosi yelayimu ye-3 kg/t, ixesha lonyango lwe-alkaline leeyure ezi-2, idosi ye-arhente yegolide ye-Jinchan enobuhlobo nokusingqongileyo ye-600 g/t, kunye nexesha lokukhupha idayi yeeyure ezingama-24, izinga lokuphuma kwegolide linokufikelela kwi-95.60%. Xa kuthelekiswa nokuphuma kwe-cyanide, izinga lokuphuma liyanda nge-1.4%, ukusetyenziswa kwe-reagent kwehla nge-200 g/ton, kwaye ixesha lokuphuma lifinyezwa ngeeyure ezingaphezu kwe-12. Ngaphezu koko, uhlalutyo lwe-leaching Toxicity lwe-residue ye-arhente yegolide ye-leaching enobuhlobo nokusingqongileyo ye-Jinchan lubonise ukuba amaxabiso etyhefu yokuphuma kwidayi ye-cyanide, i-copper, i-lead, i-zinc, kunye ne-arsenic kwi-tailings zonke zingaphakathi kwemida yesizwe kwaye zinokukhutshwa ngokuthe ngqo ngaphandle kwesidingo sokukhupha ityhefu.

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.

Ukutshintshwa kwe-sodium cyanide nge-Jinchan ekhupha igolide enobuhlobo nokusingqongileyo kubonisa ukuzinikela komgodi ekukhuseleni iNdalo . I-sodium cyanide ibisoloko ingumgangatho weshishini lokukhupha igolide, kodwa ubuthi bayo bubeka imingcipheko ebalulekileyo kwindalo nakwimpilo yabantu. Ngokwahlukileyo koko, i-Jinchan agent ibonelela ngenye indlela ekhuselekileyo nezinzileyo, iqinisekisa ukuba inkqubo yokukhupha igolide ayizi ngomonakalo kwindalo. Olu tshintsho oluya kwiindlela ezinobuhlobo nokusingqongileyo lunceda inkqubo yendalo yasekuhlaleni kwaye lumisela umzekelo omhle kushishino olubanzi lwemigodi.

Iprojekthi yokukhupha i-cyanidation egcweleyo kwiWenyu Gold Mine yimbali ebalulekileyo kwinkampani yethu ekusekeni umgodi ongena-cyanide. Le projekthi igxininisa kwiindlela zokukhusela okusingqongileyo, isebenzisa ubuchwepheshe obutsha obufana ne-Jinchan ejenti yokukhupha igolide enobuhlobo nokusingqongileyo, nto leyo ekhokelela kwiindlela zokucubungula i-ore yegolide ezizinzileyo nezinoxanduva. Umgodi wegolide waseWenyu ubonisa ukuba izinto ezixabisekileyo ezifana negolide zinokukhutshwa ngokufanelekileyo ngaphandle kokonakalisa okusingqongileyo, nto leyo ebeka umgangatho omtsha kushishino. Le projekthi ingqina ukuba iindlela zokwemba ezinoxanduva kunye nolawulo lokusingqongileyo zinokuhamba kunye, zivula indlela yekamva elizinzileyo kwezemigodi.
