Ana Ciro Zinare daga Oxidized Gold Ore

A cikin yanayi, zinari ba ya amsa tare da oxygen don samar da oxides kamar baƙin ƙarfe ko jan karfe. Ko an binne a cikin kaburbura, yashi, ko kuma a kan gadon teku na dubban shekaru, gwal ɗin zinariya, hatsi, da sanduna suna ci gaba da haskakawa.

Don haka, idan zinari ba ya oxidize, menene ainihin oxidized zinariya tama?

Fahimtar Oxidized Gold Ores

Oxidized zinare yana nufin zinari - irin tama da aka samar ta hanyar tsarin iskar oxygen na halitta, maimakon zinariya oxides.

Irin waɗannan ma'adanai galibi suna ɗauke da zinari tare da oxides na ƙarfe kamar ƙarfe, jan ƙarfe, da manganese. Babban ma'adanai sune limonite da pyrite, ba tare da kaɗan ko babu sulfide ba, amma sun haɗa da ma'adanai masu ƙarfi na biyu kamar zinariya - ɗauke da baƙin ƙarfe hydroxides ko hydrated iron oxides, tare da wasu ma'adini.

Yanayin sararin sama yana canza ma'adinan sulfide na farko zuwa oxides da hydroxides, tare da yuwuwar zinari a sanya shi cikin hematite, goethite, ko limonite.

Oxidized zinariya takin yawanci bayyana rawaya zuwa launin ruwan kasa kuma yana da sako-sako da rubutu. Yana da mahimmancin albarkatun kasa don samar da zinariya.

Yadda ake Cire Zinare daga Oxidized Gold Ore?

A cikin ma'adinin zinare mai oxidized, yawancin gwal na ƙunshe a cikin manyan ma'adinan gangue da fashewar ƙarfe oxides. Girman barbashi na zinariya ya bambanta sosai, kuma abun da ke cikin ma'adinai yana da sauƙi.

Kafin fara aikin murkushewa da niƙa, riga-kafin kula da ma'adinin gwal tare da allon trommel mataki ne mai mahimmanci don haɓaka haɓakar fa'ida, musamman ga nau'in zinare mai oxidized mai ɗauke da yumbu.

Daga bisani, hakar gwal za a iya yi ta amfani da hanyoyi kamar rabuwar nauyi, cyanidation, ku tsibi leaching.

Mataki na 1: Crushing Ore

Crushing yana rage girman oxidized zinariya tama kuma yawanci ana yin ta ta amfani da busasshen tsari tare da matakai biyu zuwa uku a jere: firamare, sakandare, da sakandare.

Bayan murkushe, ana amfani da allo mai girgiza don rarraba taman gwal mai oxidized. Ƙananan barbashi suna wucewa ta cikin buɗewar allo yayin da manyan barbashi suka rage akan fuskar allo kuma ana dawo dasu don ƙarin murkushewa.

Mataki na 2: Nikawar Ore

Nika yana fitar da gwal daga ma'adinan gangue a cikin taman gwal mai oxidized, yana haifar da yanayi mai kyau don cin gajiyar gaba. Kayan aikin niƙa na gama-gari sun haɗa da injinan ƙwallo da injinan rigar kwanon rufi.

Mataki na 3: Amfanin Ore

Amfanin taman zinari mai Oxidized tsari ne mai rikitarwa kuma mai mahimmanci. Za'a iya zaɓar hanyoyin haɓaka daban-daban bisa ga yanayin ma'adinai da nau'in zinari. Wadannan hanyoyi ne na gama gari da yawa:

1. Rabuwar nauyi

Rabuwar nauyi hanya ce ta zahiri wacce ke amfani da bambanci a takamaiman nauyi tsakanin tama na gwal da ma'adinan gangue don rabuwa.

Kayan aikin rarrabuwar takin da aka fi amfani da shi na gwal da aka yi amfani da su sun haɗa da tebur mai girgiza, karkace chute, jig, da sauransu.

2. Cyanidation

Hanyar cyanidation ita ce hanyar sinadaran da aka fi amfani da ita don hakar gwal. Ya dace da ƙanana da matsakaici - ma'auni na ma'adinai na zinariya oxidized, musamman ma waɗanda ke da girman ƙwayar ƙwayar cuta da babban matsayi.

Bayan an yi niƙa, ana haɗe tama ɗin gwal mai oxidized da cyanide bayani, kuma zinaren yana narkar da shi a cikin ruwa ta hanyar leaching dauki, sa'an nan kuma an dawo da zinariya ta hanyar kunna carbon adsorption ko hazo zinc.

Cyanidation yana ba da ƙimar dawo da zinari mai girma da kuma fa'ida mai fa'ida amma ya haɗa da hadaddun ayyuka da tsada mai tsada saboda buƙatar sarrafa sharar cyanide.

3. Leaching

Tuba leaching ya dace da ƙarancin daraja ko manyan ɗigon gwal mai oxidized, sau da yawa ba tare da niƙa ba.

Bayan an murkushe ta, ana tara takin gwal akan ɗigo-tabbataccen tulin leaching, yana samar da tulin tama. Ana fesa maganin Cyanide akan tari don narkar da gwal, wanda daga nan aka samo shi daga maganin leach.

Wannan tsari yana da ƙananan farashi na saka hannun jari, aiki mai sauƙi, daidaitawa mai faɗi, kuma ya dace da manyan - sikelin hakar ƙananan ma'adinai na zinariya. Koyaya, yana buƙatar takamaiman girman barbashi na tama, saboda ƙananan barbashi na iya shafar ingancin leaching.

Waɗannan su ne manyan hanyoyi guda uku don sarrafa taman gwal mai oxidized. Don ma'adinan da aka yi da oxidized, rabuwar nauyi da cyanidation galibi ana haɗa su.

Sarrafa taman gwal mai oxidized ya dogara da yanayin ma'adinin da nau'in zinari. Ta hanyar zabar hanyoyin samun fa'ida mafi dacewa da inganta murkushewa, niƙa, da hanyoyin rabuwa, ana iya haɓaka ƙimar dawo da gwal da haɓaka fa'idodin tattalin arziki.

Shanxi United Chemical yana samar da inganci mai inganci Sodium cyanide ta hanyar fasahar zamani da kayan aiki. Don tambayoyin fasaha da suka danganci cyanidation tama na gwal, leaching, da sauransu, zaku iya tuntuɓar mu a kowane lokaci. Mun taimaka abokan ciniki cimma mafi inganci da kuma barga zinariya dawo da.
