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 ye-Akmola ungowohlobo lwe-sericite- olutshintshiweyo lwamatye kunye negolide ephantsi yesulfide-ethwele uhlobo lwe-quartz vein. Isayizi yengqolowa yokusasazwa kwegolide ilungile kakhulu, isasazwa ngokungalinganiyo, kwaye inobudlelwane obubi kunye neesulfides. I-ore iqulethe ixabiso elincinci legolide lemveli, i-pyrite, i-chalcopyrite, i-bismuth - i-tellurium sulfides, kunye ne-galena, i-sphalerite, njl., kwaye yeyo intsimbi ekrwada edadayo yegolide. Kwinqanaba lokuqala lokumbiwa kwemigodi, iindlela zemveli kwakunzima ukucutshungulwa ngokufanelekileyo ore ezintsonkothileyo ezinjalo, okubangele ukuba kuphantsi izinga lokubuyisela igolides, inkcitho yemithombo emandla, kunye nophuculo olunzima lweenzuzo zoqoqosho.

II. Inkqubo eYilwayo kunye nendima ephambili yeSodium Cyanide

Emva kweemvavanyo ezininzi, kwafunyaniswa ukuba igolide imfumba yokuvuza Inkqubo yeyona ndlela ifanelekileyo yokunyanga le ntsimbi. Kule nkqubo, i-sodium cyanide idlala indima ebalulekileyo.

Umgangatho ophezulu we-sodium cyanide esibonelela ngayo ubonise ukusebenza okugqwesileyo kwi inkqubo yegolide leaching kulo mgodi wegolide. Inkqubo yokucoca igolide inolawulo oluqinileyo kunye nesayensi malunga nokugxininiswa kwe-agent ye-sodium cyanide leaching agent: kwinqanaba lokuqala, ukuxinwa kwe-sodium cyanide leaching agent ilawulwa kwi-0.10%, kunye nobukhulu bokuqala bokutshiza yi-20 - 30L / (TPD); emva kwenqanaba eliphakathi, ukugxininiswa kuncitshiswe kwi-0.05% - 0.08%, kwaye kwinqanaba lokugqibela, lihlengahlengiswa kwi-0.03% - 0.05%. Umlinganiselo wesithuba sokutshiza yi-1:2. Xa kukho iingxaki ezicacileyo zokuphuma kwamanzi kwimfumba, amandla okutshiza kunye nomlinganiselo wekhefu lokutshiza uya kulungelelaniswa ngexesha elifanelekileyo. I-leached rich liquid i-adsorbed kuyo yonke inkqubo, kwaye i-adsorption intensity yi-12 - 20 L / (tpd). Xa ibakala le-liquid ecebileyo lingaphantsi kwe-0.2g / m3 okanye akukho nzuzo yezoqoqosho, i-leaching iphela.

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 lobuchwephesha lobuchwephesha libonelele ngenkqubo ejikelezayo nepheleleyo uxhaso lobuchwepheshe kumgodi wegolide. Ukususela ekuqaleni kweprojekthi, siye sangena nzulu kwindawo yemigodi. Ngokujonga iimpawu ezintsonkothileyo zentsimbi ekrwada kumgodi wegolide, sincede iqela lomgodi wegolide ekuqulunqeni isicwangciso esicacileyo nesichanekileyo senkqubo yokucoca imfumba ukuqinisekisa ukuba i-sodium cyanide inokusebenzisa ukusebenza kwayo kakuhle phantsi kwezona meko zifanelekileyo.

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.
