Ithiyori yeFlotation yeGold Ore

Igolide isoloko iveliswa kwindawo ekhululekileyo kwi-ores.Ezona zimbiwa zixhaphakileyo yigolide yendalo kunye neentsimbi zesilivere-zegolide.Onke ayakwazi ukudada kakuhle, ngoko ke ukuphaphazela yenye yeendlela ezibalulekileyo zokulungisa iintsimbi zegolide.Igolide idla ngokudityaniswa neeminerali ezininzi zesulfide.I-Symbiotic, ngakumbi ihlala i-symbiotic kunye ne-pyrite, ngoko ke ukudada kwegolide kunye nokujikeleza kwentsimbi ye-sulfide yesinyithi efana ne-pyrite ephethe igolide kuhambelana ngokusondeleyo ekusebenzeni.Iinkqubo zokudada eziziintloko ezininzi esiza kuzizisa ngezantsi ubukhulu becala zizimbiwa zegolide apho igolide kunye neeminerali zesulfide zihlalisana.

Ngokuxhomekeke kuhlobo kunye nobuninzi be-sulfides, iindlela zonyango ezilandelayo zingakhethwa.
① Xa i-sulfide kwintsimbi ekrwada ubukhulu becala iyi-pyrite, kwaye ingekho enye i-sulfide yesinyithi enzima, kwaye igolide ikakhulu iphakathi kunye namasuntswana amahle kunye ne-symbiotic nge-iron sulfide.Ezo ore zintandwa ukuze zivelise i-sulfide concentrates yegolide, kwaye i-flotation concentrates iye ivuzwe kukuvuza kwe-atmosphere, ngaloo ndlela kuthintelwa ukunyangwa kwe-cyanidation yayo yonke intsimbi ekrwada.I-flotation concentrate nayo inokuthunyelwa kwiplanti yepyrometallurgy ukuze ilungiswe.Xa igolide ubukhulu becala ikwimo yamasuntswana e-submicroscopic kunye nepyrite, i-cyanide leaching effect yeconcentrate ayilunganga, kwaye kufuneka yojiwe ukuze ihlukanise amasuntswana egolide emva koko ivuzwe ngumoya.

② Xa i-sulfide kwintsimbi ekrwada iqulethe i-chalcopyrite encinci, i-sphalerite, kunye ne-galena ukongeza kwi-iron sulfide, igolide i-symbiotic kunye ne-pyrite kunye nezi sulfide zetsimbi enzima.Isicwangciso sonyango ngokubanzi: Ngokwenkqubo yesiqhelo kunye nenkqubo yeekhemikhali ye-non-ferrous metal sulfide ore, bamba kwaye ukhethe i-concentrate ehambelanayo.I-concentrate ithunyelwa kwi-smelter ukuze iqhutywe.Igolide ingena kubhedu okanye ilothe (idla ngokugqwesa ubhedu olungakumbi) igxininise kwaye ibuyiswe kwakhona ngexesha lenkqubo yokunyibilikiswa.Inxalenye apho igolide kunye ne-iron sulfide zisebenza kwi-symbiotic zinokuhanjiswa ukuze kufunyanwe i-iron sulfide concentrate, enokuthi ke ifumaneke ngokurosa kunye nokuvuza emoyeni.

③ Xa kukho iisulfide ezinobungozi emoyeni kwintsimbi ekrwada, njenge arsenic, iantimony, kunye neesulfide zesulfide, i-sulfide concentrate efunyenwe ngokudada kufuneka yojiwe ukutshisa iarsenic, isulfide kunye nezinye izinyithi ekugxininiseni zibe lula. , gaya i-slag kwakhona kwaye usebenzise ipeni ukuze ususe i-oxides yensimbi eguquguqukayo.

④ Xa inxalenye yegolide kwintsimbi ekrwada ikhona kwindawo ekhululekileyo, inxalenye yegolide ine-symbiotic ne-sulfide, kwaye inxalenye yamasuntswana egolide afakwe kwiminerali ye-ganggue.Ezo ntsimbi kufuneka zibuyiswe ngokuhlukana komxhuzulane ukuze kubuyiselwe igolide esimahla, kunye nokubuyisela i-symbiosis kunye nesulfide ngokudada kwigolide, ngokuxhomekeke kwisiqulatho segolide seentsalela zezimbiwa ezidadayo, kuyafuneka ukuba kuqwalaselwe ukuba kuyasetyenziswa na ukusetyenziswa kwemichiza.I-flotation concentrate inokucolwa kwaye emva koko ivundiswe ngokuthe ngqo, okanye intsalela etshisiweyo inokucolwa emva kokuba itshisiwe ize itshiswe.
