Impembelelo yamaBanga ahlukeneyo eOre ekuSetyenzisweni kweSodium Cyanide kwiMisebenzi yeMigodi

Kwindawo yemigodi, ngakumbi kwiinkqubo zokukhutshwa kwegolide apho i-cyanidation yindlela eqhelekileyo, ukuqonda ubudlelwane phakathi Ibakala ore kwaye Isodium cyanide ukusetyenziswa kubalulekile. Isodium i-cyanide idlala indima ebalulekileyo ekunyibilikiseni igolide kwi-ore matrix, kodwa isixa esifunekayo singohluka kakhulu ngokuxhomekeke kwibakala lentsimbi ekrwada elungiswayo.

Ukuqonda iBanga leOre

Umgangatho wentsimbi ekrwada ubhekisa kuxinzelelo lweminerali exabisekileyo, efana negolide, ngaphakathi kwentsimbi ekrwada. I-ore yomgangatho ophezulu iqulethe isixa esikhulu seminerali efunwayo, ngelixa i-ore yomgangatho ophantsi inoxinzelelo olusezantsi kakhulu. Umzekelo, intsimbi ekrwada yegolide yodidi oluphezulu isenokuba neegram ezininzi zegolide ngetoni yentsimbi ekrwada, lo gama intsimbi ekrwada yodidi oluphantsi inokuba ngaphantsi kwegram enye ngetoni nganye.

Inkqubo yeCyanidation

The Inkqubo ye-cyanidation setyenziso sodium cyanide izisombululo zokusabela ngegolide kwintsimbi ekrwada. Phambi kweoksijini, i-ion cyanide kwindawo Isodium cyanide isisombululo dibanisa negolide ukwenza i-soluble complex. Le mpendulo yemichiza ivumela igolide ukuba yahlulwe kwi-ore matrix, okwenza kube lula ukuyikhupha. Inkqubo isetyenziswa kakhulu kuba iyasebenza ekukhupheni igolide kwiintlobo ngeentlobo zentsimbi.

Impembelelo yeBanga leOre ekuSetyenzisweni kweSodium Cyanide

High - Grade Ores

USetyenziso olunxulumeneyo olusezantsi: Xa usebenzisana ne-ores yodidi oluphezulu, isixa sesodium cyanide efunekayo ngeyunithi yeminerali exabisekileyo (umz., ngegram yegolide) isoloko ingaphantsi. Oku kungenxa yokuba kukho ukuxinana okuphezulu kweminerali ekujoliswe kuyo kumthamo omncinci wentsimbi ekrwada. Umzekelo, ukuba intsimbi ekrwada yegolide yodidi oluphezulu ineegram ezili-10 zegolide ngetoni nganye, kwaye ifuna i-2 kg yesodium cyanide ngetoni yentsimbi ekrwada ukuphumeza umlinganiselo osebenzayo wokutsalwa, Ukusetyenziswa kwe-sodium cyanide ngegram yegolide yi-0.2 kg. Umlinganiselo ophantsi we-ganggue (iiminerali ezingenaxabiso kwintsimbi ekrwada) kwi-ore yomgangatho ophezulu kuthetha ukuba kukho ukusabela okusecaleni okumbalwa okunokusebenzisa icyanide.

I-Faster Reaction Kinetics: Iintsimbi zodidi oluphezulu zikholisa ukusabela ngokukhawuleza ngesisombululo secyanide. Uxinaniso oluphezulu lwezimbiwa ekujoliswe kuzo lubonelela ngeziza ezininzi ze-cyanide - ukusabela kwegolide ukuba kwenzeke. Ngenxa yoko, inkqubo yokukhutshwa ingagqitywa ngexesha elifutshane, elinokuthi libe negalelo ekunciphiseni ukusetyenziswa kwe-cyanide. Oku kungenxa yokuba okukhona isisombululo secyanide sidibana nentsimbi ekrwada, kokukhona sityiwa ziintshukumo ezisecaleni ezifana nehydrolysis okanye ukusabela kobunye ukungcola kwintsimbi ekrwada.

Phantsi - Grade Ores

Ukusetyenziswa okuPhakamileyo okunxulumeneyo: I-ores yomgangatho ophantsi ngokubanzi ifuna inani eliphezulu le-sodium cyanide ngeyunithi yeminerali exabisekileyo. Qwalasela intsimbi ekrwada yegolide yodidi oluphantsi equlethe kuphela i-0.5 grams yegolide ngetoni nganye. Ukufezekisa izinga elifanelekileyo lokutsalwa, kunokufuna i-1.5 kg ye-sodium cyanide ngetoni ye-ore. Kule meko, ukusetyenziswa kwe-sodium cyanide ngegram yegolide yi-3 kg, ephezulu kakhulu kunomzekelo ophezulu we-ore. Isizathu soku kukuba kukho umthamo omkhulu weeminerali ze-ganggue kwi-ores yomgangatho ophantsi. Ezi zimbiwa ze-ganggue zinokusabela kunye ne-cyanide, mhlawumbi ngokwenza ii-complex okanye ngokutya i-oksijini kwisisombululo, zombini ezo zinyusa imfuno ye-cyanide.

Amazinga okusabela asezantsi: Inkqubo yokukhutshwa kweentsimbi zomgangatho ophantsi idla ngokucotha. Uxinzelelo olusezantsi lweminerali ekujoliswe kuyo kuthetha ukuba iiyoni zecyanide kufuneka zikhangele kumthamo omkhulu wentsimbi ekrwada ukuze zifumane kwaye zisabele ngegolide. Eli xesha lide lokuphendula linokukhokelela ekusetyenzisweni okwandisiweyo kwecyanide ngenxa yeempendulo ezisecaleni. Ukongeza, kwezinye iimeko, ukuhlawula ireyithi yokusabela kade, ukugxila okuphezulu kwecyanide kunokusetyenziswa kwisisombululo, ukonyusa ngakumbi ukusetyenziswa kukonke.

Eminye imiba echaphazela uBudlelwane

Imineraloji yeNsimbi: Ubukho bezinye iiminerali kwintsimbi ekrwada bunokuba nefuthe kakhulu ekusetyenzisweni kwecyanide nokuba leliphi ibakala. Izimbiwa ezifana nobhedu, i-zinc, i-arsenic, kunye ne-antimony zinokusabela nge-cyanide, zenze izakhiwo ezizinzileyo kwaye ngaloo ndlela zitya i-cyanide ebinokuthi ifumaneke xa kutsalwa igolide. Umzekelo, iiminerali zobhedu zinokusabela nge-cyanide ukwenza i-copper-cyanide complexes, kwaye ukuba i-ore iqulethe isixa esikhulu sobhedu, ukusetyenziswa kwe-cyanide kuya kwanda kakhulu, nakwinqanaba eliphezulu legolide.

Ubungakanani beNcam kunye neNdawo yoMphezulu: Ubungakanani bamasuntswana ore kunye nommandla wabo ongaphezulu nawo adlala indima. Iintsimbi ezicolekileyo eziphantsi komhlaba zinommandla omkhulu, onokuthi uphucule unxibelelwano phakathi kwesisombululo secyanide kunye namasuntswana egolide. Nangona kunjalo, ukuba intsimbi idlulile emhlabeni, isenokwandisa ubungakanani beminerali ye-ganggue evezwayo nefumanekayo ukusabela ngecyanide. Lo mba unokuchaphazela ukusetyenziswa kwe-cyanide ngokwahlukileyo kwimigangatho ephezulu kunye nesezantsi, kodwa ngokubanzi, ulawulo olululo lobungakanani bamasuntswana lubalulekile ukuze kwandiswe ukusetyenziswa kwecyanide.

isiphelo

Isishwankathelo, ibakala le-ore linempembelelo enkulu kumlinganiselo we-sodium cyanide efunekayo kwinkqubo ye-cyanidation. I-ore yodidi oluphezulu idla ngokufuna i-sodium cyanide encinci kwiyunithi nganye yeminerali exabisekileyo kwaye ibe ne-kinetics yokusabela ngokukhawuleza, ngelixa i-ores yodidi oluphantsi ifuna izixa eziphezulu ze-cyanide kwaye zihlala zinemilinganiselo yokusabela kancinane. Nangona kunjalo, ezinye izinto ezinje nge-mineralogy ye-ore kunye nobungakanani bamasuntswana nazo kufuneka ziqwalaselwe ngononophelo xa kumiselwa idosi ye-sodium cyanide efanelekileyo kwimisebenzi yezemigodi. Ngokuqonda obu budlelwane, abasebenzi basezimayini banokusebenza ngokufanelekileyo kunye neendleko - ngokufanelekileyo ukukhupha iiminerali ezixabisekileyo ngelixa benciphisa impembelelo yokusingqongileyo ehambelana nokusetyenziswa kwe-sodium cyanide.
