IProjekthi ye-Heap Leaching yoMgodi weGolide kwiNgingqi yase-Akmola, eKazakhstan

Kwinkalo yokwembiwa kwegolide, ubugcisa bokugrumba obusebenzayo kunye nezixhobo zekhemikhali ezikumgangatho ophezulu zibalulekile ekwandiseni imveliso nokuphucula izibonelelo zoqoqosho. Namhlanje, siza kugxila kwi-a umgodi wegolide kwiNgingqi yaseAkmola, eKazakhstan, kwaye uphonononge ngokunzulu utshintsho olumangalisayo oluziswe emva kokusebenzisa umgangatho ophezulu. sodium cyanide inikwe yinkampani yethu.

I. Imingeni yeProjekthi yoMgodi weGolide kwiNgingqi yase-Akmola

Umgodi wegolide kwiNgingqi yaseAkmola ngowe-sericite - uhlobo lwelitye elitshintshiweyo kunye nohlobo lwe-quartz ene-sulfide ephantsi. Ubungakanani bengqolowa yokusasazwa kwegolide buncinci kakhulu, abusasazwanga ngokulinganayo, kwaye bunobudlelwane obubi ne-sulfides. I-ore inexabiso elincinci legolide yendalo, i-pyrite, i-chalcopyrite, i-bismuth - i-tellurium sulfides, kunye ne-galena, i-sphalerite, njl.njl., kwaye yeye- refractory floating gold ore . Kwinqanaba lokuqala lokumba, iindlela zemveli zazinzima ukuzicubungula ngempumelelo ezi ore zintsonkothileyo, nto leyo ebangele ukuba izinga lokubuyiselwa kwegolide liphantsi , inkunkuma enkulu yezixhobo, kunye nokuphuculwa okunzima kwezibonelelo zoqoqosho.

II. Inkqubo eYilwayo kunye nendima ephambili yeSodium Cyanide

Emva kovavanyo oluninzi, kwafunyaniswa ukuba inkqubo yokukhupha igolide kwi-gold heap yeyona ndlela ifanelekileyo yokunyanga le ore. Kule nkqubo, i-sodium cyanide idlala indima ebalulekileyo.

I-sodium cyanide esemgangathweni esibonelela ngayo ibonakalise ukusebenza kakuhle kakhulu kwinkqubo yokukhupha igolide kule migodi yegolide. Inkqubo yokukhupha igolide inolawulo oluqinileyo nolwenzululwazi malunga noxinzelelo lwe-sodium cyanide leaching agent: kwinqanaba lokuqala, uxinzelelo lwe-sodium cyanide leaching agent lulawulwa kwi-0.10%, kwaye amandla okuqala okutshiza yi-20 - 30L/(TPD); emva kwenqanaba eliphakathi, uxinzelelo luncitshiswa luye kwi-0.05% - 0.08%, kwaye kwinqanaba lokugqibela, luhlengahlengiswa luye kwi-0.03% - 0.05%. Umlinganiselo wexesha lokutshiza yi-1:2. Xa kukho iingxaki ezicacileyo zokuvuza kwinqwaba, amandla okutshiza kunye nomlinganiselo wexesha lokutshiza uya kulungiswa ngexesha elifanelekileyo. Ulwelo olutyebileyo olukhutshwe lufunxwa kuyo yonke inkqubo, kwaye amandla okufunxwa yi-12 - 20 L/(tpd). Xa umgangatho wolwelo olutyebileyo ungaphantsi kwe-0.2g/m3 okanye kungekho nzuzo yezoqoqosho, ukufunxwa kuyaphela.

Emva kokuba i-leaching igqityiwe, ukuze kuqinisekiswe ukuthotyelwa kokusingqongileyo, i-calcium hypochlorite eqinileyo isasazwa kumphezulu wemfumba emva koko itshizwe ngamanzi. Xa i-p (CN -) kulwelo lwe-reflux ingaphantsi kwe-0.5×10. ukubulawa kweentsholongwane kuyahlangabezana nemigangatho. I-Residu ye-Leaching ingathuthelwa kwindawo yokulahla i-slag, kwaye i-liquid inkunkuma ikhutshwe ngokuthe ngqo.

III. Impumelelo ephawulekayo

Kuyo yonke inkqubo yentsebenziswano, iqela lethu leengcali zobugcisa libonelele ngenkxaso yobugcisa epheleleyo nepheleleyo kwimigodi yegolide. Ukususela ekuqaleni kweprojekthi, singene nzulu kwindawo yokwemba. Ngenxa yeempawu ezintsonkothileyo zemigodi yegolide, sincede iqela lemigodi yegolide ekwenzeni isicwangciso senkqubo yokukhupha inqwaba eneenkcukacha nezichanekileyo ukuqinisekisa ukuba i-sodium cyanide inokusebenza kakuhle phantsi kweemeko ezifanelekileyo.

Ngexesha lenkqubo yokukhutshwa kwegolide, amagcisa amiswa kwisiza ixesha elide ukujonga iiparameters zenkqubo ngexesha lokwenyani. Ngokotshintsho lwezalathisi eziphambili ezifana nokugxininiswa kwe-agent ye-sodium cyanide leaching agent, ukuqina kokutshiza, kunye nomlinganiselo wekhefu lokutshiza, iingcebiso zobuchwephesha zanikezelwa ngexesha elifanelekileyo kwaye kwenziwa uhlengahlengiso. Umzekelo, xa iingxaki ze-seapage zifunyenwe kwimfumba, iingxoxo zobugcisa zacwangciswa ngokukhawuleza, kwaye isicwangciso sokutshiza saphinda salungiswa ukuze kuqinisekiswe inkqubela phambili yenkqubo yokucoca.

Kwangaxeshanye, siye saqhuba imijikelo emininzi yoqeqesho lobuchule kubasebenzi bomgodi wegolide. Umxholo woqeqesho wawubandakanya ukusetyenziswa ngokukhuselekileyo kwe-sodium cyanide, ukusebenza kunye nokugcinwa kwezixhobo zokukhupha imfumba, kunye neengxaki eziqhelekileyo kunye nezisombululo kwinkqubo yokucoca. Ngendibaniselwano yethiyori kunye neendlela zoqeqesho olusebenzayo, izakhono zobuchwephesha kunye namanqanaba okusebenza kweqela lomgodi wegolide aphuculwe ngokusebenzayo.

Ngokuchanekileyo kuphantsi kwenkxaso yethu yobugcisa eqhubekayo kunye neenkonzo apho izinga lokufunyanwa kwegolide kulo mgodi wegolide linyuswe ngempumelelo laya kutsho kuma-77%. Imveliso yegolide ayinyukanga kakhulu kuphela, kodwa neendleko zemveliso ziye zancitshiswa kakhulu. Ezi mpumezo azibonisi kuphela ukusebenza okugqwesileyo kwe-sodium cyanide yethu ekumgangatho ophezulu kodwa ikwabonakalisa amandla awomeleleyo eqela lethu lobuchwephesha lobuchwephesha.

Kumashishini emigodi yegolide eKazakhstan nakweminye imimandla yehlabathi, ukukhetha umgangatho ophezulu we-sodium cyanide linyathelo elibalulekileyo lokuphucula ukukhuphisana kunye nokufezekisa uphuhliso oluzinzileyo. Njengomthengisi ochwepheshile we-sodium cyanide, inkampani yethu iya kuqhubeka nokugcina intanda-bulumko yomgangatho wokuqala kunye nenkonzo-ejolise, kwaye ibonelele ngeemveliso ezikumgangatho ophezulu kunye neenkonzo kushishino lwemigodi yegolide yehlabathi. Ukuba umgodi wakho wegolide ufuna izisombululo ezisebenza ngokufanelekileyo nezinoqoqosho, wamkelekile ukuba uqhagamshelane nathi kwaye ngokudibeneyo uvule isahluko esitsha kwimigodi yegolide.
