Zeziphi izixhobo zokutsala igolide?

Indlela yokukhupha igolide kwiibhodi zeesekethe?

Izixhobo ezidityanisiweyo zokutsalwa kwegolide: izixhobo ezinkulu ze-electroplating ezipheleleyo / igolide kunye nesilivere umatshini wokubuyisela i-electrolysis, ikhabhinethi yokuphefumla, umatshini wokuthulula amanzi, iketile yokuphendula iglasi, i-aqua regia filtration car, inkqubo ye-Ph automatic dosing, ukunciphisa kunye nokucoca umatshini odibeneyo, i-sponge yegolide yokuhluza umgqomo, itanki yokunciphisa i-PP, itanki ye-neutralization, i-kettle yokuphendula kabini, i-kettle ephindwe kabini ye-galten yonyango, njl.

Uluhlu lwexabiso lezixhobo zokusulungekisa igolide kwiibhodi zesekethe likhulu kakhulu, ukusuka kumashumi amawaka ukuya kumakhulu amawaka. Ixabiso liphenjelelwa zizinto ezinje ngobungakanani bemodeli yesixhobo, imathiriyeli yokuvelisa, umgangatho, uyilo lwenkqubo, kunye nobungakanani bemveliso, kwaye inokuhla inyuka. Kunzima ukumisela ixabiso elimiselweyo, kwaye abavelisi banokubonelela kuphela ngekowuteshini ethile emva kokumisela iimfuno zakho kunye neemeko ezithile zokusebenza.

Izixhobo zokusulungekisa isinyithi esixabisekileyo zisetyenziselwa ikakhulu ukukhupha iintsimbi ezixabisekileyo ezifana negolide, isilivere, iplatinum, i-palladium, njl njl. Okwangoku, i-Fuxin Environmental Refining isebenzisa ikakhulu iindlela ezifana nokucocwa kwe-chlorination, ukuhlanjululwa kwe-aqua regia, ukuhlanjululwa kwe-electrolysis, ukucocwa kwe-chloramine, njl.

Izixhobo ezisetyenziswa ngokuqhelekileyo ziquka: izixhobo ezipheleleyo zokucoca i-electroplating / igolide kunye nesilivere umatshini wokubuyisela i-electrolysis, ikhabhathi yokuvula umoya, umatshini wokutshiza amanzi, iketile yokuphendula iglasi, imoto yokucoca i-aqua regia, inkqubo ye-Ph automatic dosing, ukunciphisa kunye nokucoca umatshini odibeneyo, i-sponge yegolide yokucoca umphanda, itanki yokusabela yokunciphisa i-PP, itanki ye-neutralization, i-kettle ephindwe kabini yokuphendula i-kettle yokunyibilika kwegolide, kunye nezixhobo zokucoca igesi.

Zeziphi iindlela zokukhupha iintsimbi ezixabisekileyo kwigolide?

Igolide yimveliso yendalo engenakwenziwa ngokufanelekileyo, kwaye ihlukaniswe ibe yigolide eluhlaza kunye negolide ephekiweyo. Igolide efikelele kubunyulu obuphezulu emva kokusulungekiswa ibizwa ngokuba yigolide esulungekileyo, idla ngokubhekisa kwigolide enokulunga okungaphezulu kwama-99.6%. Igolide ehlanjululweyo ngokubanzi yococeko oluphezulu, kwaye ezinye zingasetyenziselwa ngokuthe ngqo ukuveliswa kwemveliso.

1. Isulungekiswa njani iGolide

I-Flotation enye ilungele ukusetyenzwa kwentsimbi ekrwada kunye nephakathi ekukhozo kuyo igolide yentsimbi yendalo. Intsimbi ekrwada etyunyuziweyo ifakwa kwilitye lokusila, igaywe ibe ludaka, emva koko ingene kwiflotation. I-Mixed mercury flotation ilungele ukusetyenzwa kwegolide yendalo kunye nobungakanani besuntswana elirhabaxa, eligcinwe kwipyrite kunye nezinye i-sulfide ores. Ngokungafaniyo ne-flotation enye, ukongeza ipleyiti ye-mercury emva kokusila ukubuyiswa kwegolide kunokufikelela kumlinganiselo wokubuyisela we-30-45%. Ukuhanjiswa kwebhanti kwiyadi yeentsimbi; Isanti yentsimbi engekho nkulu kunomngxuma wesihluzo iyondliwa kumatshini we-1-3 wesigaba setyhula setyhula ngokuxutywa koluntu, kwaye i-concentrate igeleza kwitafile eshukumayo ngenqanaba eli-3 lomatshini wokuhluza ngokurhabaxa, ocolekileyo, kunye nokhetho lokutshayela ukuvelisa intsimbi yesanti entle. Le ndlela isoloko isetyenziselwa imigodi yentlabathi ekhawulezayo, kwaye intsimbi ekrwada ecolekileyo ingasetyenziswa.

2. Intshayelelo yeNdlela yokuKhipha iGolide ngokuxuba iMercury kunye neGold Purification

Oku ngokwenene yindlela yamandulo yokuhlanjululwa kwegolide, nje ngokuba unomonde, unokukhankanya ubunyulu obuphezulu. Iindlela ezikhethekileyo zezi zilandelayo:

Igolide+imekyuri+amanzi, eqhubeka egudla de kungabikho masuntswana egolide, kwaye igolide kunye nemekyuri zenza imixube ye-intermetallic. Sila kwaye udibanise umgubo wesulfure kunye negolide ehlanganiswe nemekyuri, kwaye ushushu kwaye uyitshise emoyeni. Ngeli xesha, i-mercury eseleyo iyaphuphuma, kwaye isiseko sesinyithi senza kuqala i-sulfides yesinyithi, ethi kamva yenze i-oxides yensimbi. Phinda lo msebenzi ungentla amaxesha amaninzi kwaye wongeze iboraksi ukuze inyibilike kwiingots zegolide. Iioksidi zentsimbi ezisisiseko zidibana neboraksi zenze iindawo ezisezantsi zokunyibilika, ezidada kumaleko angaphezulu olwelo. Igolide esulungekileyo iya kusebenzisa le ndlela esezantsi ukuthintela ukutyhefeka komphunga wemercury.

3. Intshayelelo yeNkqubo yokuTshintsha iGolide emanzi yokuKhipha iGolide

Inkqubo yokuhlanjululwa kwegolide emanzi ithatha indlela yokunyibilika kwegolide kwi-aqua regia kunye nokongeza i-agent yokunciphisa ukunciphisa igolide, okanye ukuba i-agent ye-masking isetyenziselwa izinto eziphazamisayo eziyinkimbinkimbi, ilandelwa yi-extraction kunye ne-arhente yokuqala okanye i-extractant. Oku kuqanjwa kugqabhuka kwiinkqubo zemveli ezifana nokunyibilika kobushushu obuphezulu kunye nezinye iinkqubo ezilula zokucoca ukufumana igolide ekumgangatho ophezulu. Xa kuthelekiswa nobuchwepheshe obukhoyo, ukuveliswa kwangoku kuneempawu zokuhlanjululwa kwemveliso ephezulu, ukunciphisa iindleko zemveliso, kunye neenkqubo ezilula nezisebenzayo. Enye indlela kukuhlanjululwa okumanzi kwenkqubo yegolide, ebandakanya ukubeka igolide ekrwada kwisikhongozelo, ukongeza kwi-aqua regia esandula kulungiswa ukuntywilisela igolide ekrwada, kwaye emva koko uyifudumeze ukuze inyibilike imizuzu eyi-15-25. Ukuba igolide ekrwada ayichithwanga ngokupheleleyo, i-aqua regia inokongezwa ukuze iyinyibilikise ngokuphindaphindiweyo de ibe ichithwe ngokupheleleyo.

Okokugqibela, sebenzisa oomatshini bentsimbi exabisekileyo beHasung bokwenza imivalo yegolide ekhazimlayo, bangumatshini wokugranula. umatshini wokugalela ibha yegolide umatshini wokunyibilikisa we-induction , njl.
