I-XTL sintyron Umgaqo osisiseko wovavanyo lomlilo (Umgaqo weNdlela)

EtiMnga 24, 2021

Kukho iintlobo ezininzi kunye neenkqubo ezahlukeneyo zokusebenza, kubandakanywa uvavanyo lwe-lead, uvavanyo lwe-bismuth, uvavanyo lwe-tin, uvavanyo lwe-antimony, uvavanyo lwe-nickel sulfide, uvavanyo lwe-sulfide yobhedu, uvavanyo lwe-copper-iron-nickel, uvavanyo lobhedu, uvavanyo lwentsimbi, njl njl. Nangona kunjalo, imigaqo yokunyibilikisa kunye neempendulo kwiindlela ezahlukeneyo zovavanyo olutsha zisenezinto ezininzi ezifanayo kunye nendlela yovavanyo olukhokelayo. Phakathi kwazo zonke ii-assay zomlilo, eyona nto isetyenziswa ngokuqhelekileyo kwaye ibaluleke kakhulu yi-lead assay. Inzuzo yayo kukuba isiphumo sokhokelo sinokuvuthelwa. Ukudityaniswa kovavanyo lwelothe kunye netekhnoloji yokuvuthela umsizi kunokutyebisa iintsimbi ezixabisekileyo kwishumi leegram zeesampulu kwii-aggregates ezinobunzima beemilligrams ezininzi. Kuvavanyo olukhokelayo, izinga lokuqokelela i-Au yi> I-99%, kwaye kusekho izinga eliphezulu lokubuyisela i-Au ephantsi njenge-0.2 ~ 0.3g/t. Uhlalutyo lokuchaneka kovavanyo olukhokelayo lwe-macro kunye ne-trace metal ezixabisekileyo luphezulu kakhulu. Oku kulandelayo yinkcazo emfutshane yomgaqo wovavanyo lomlilo kunye novavanyo olukhokelayo njengomzekelo.

 

Uvavanyo lomlilo olukhokelayo lwahlulwe kakhulu ngokwezigaba ezi-3:

 

(1) Ukunyibilika. Isebenzisa ii-reagents eziqinileyo ukuxubana namatye, intsimbi ekrwada okanye iimveliso ezinyibilikisiweyo, ubushushu kunye nokunyibilika kwi-crucible, kunye nokusebenzisa ilothe ukubamba igolide, isilivere kunye nesinyithi esixabisekileyo kwimeko enyibilikisiweyo ukwenza ialloys zelothe (ngokuqhelekileyo zibizwa ngokuba ngamaqhosha okukhokela, abizwa ngokuba yilothe exabisekileyo. ). Ngenxa yobunzima obuthile obuphezulu be-alloy lead, iyatshona ukuya ezantsi kwi-crucible. Kwangaxeshanye, isiseko sentsimbi oxides kunye gangue kwisampulu basabela kunye fluxes ezifana silica, borax, kunye nesodium carbonate ukwenza slag ezifana silicate okanye borate, leyo edada phezulu ngenxa yomxhuzulane ethile encinane. , Ukwahlula igolide nesilivere kwisampuli. Ke ngoko, ngexesha lenkqubo yovavanyo lomlilo, yomibini imisebenzi yokubola iisampulu kunye nokutyebisa isinyithi esixabisekileyo iyadlalwa.


(2) Ukuvuthuza luthuthu. Beka ingxubevange yelothe efunyenweyo kwi-ashtray kwiqondo lobushushu elifanelekileyo ukuze uthuthu luvuthelwe ukususa ilothe. Ngexesha lokuvuthela kothuthu, i-lead i-oxidized kwi-oxide ekhokelayo kwaye ingena kwi-ashtray ene-porous, ngaloo ndlela isusa i-lead kwiqhosha elikhokelayo kunye nexabiso elincinci lesiseko sesinyithi, igolide yeSiliva kunye neentsimbi ezixabisekileyo azikho oxidized kwaye zihlala kwisitya sothuthu ukwenza. amasuntswana egolide nesilivere.

 

(3) Igolide eyahlula intsalela . Sebenzisa iasidi yenitric ukunyibilikisa amasuntswana egolide-isilivere ehlanganisiweyo ukunyibilikisa isilivere ngelixa igolide ihlala yomelele. Emva kokucima, linganisela amasuntswana egolide ukubala umxholo wegolide. Umxholo wesilivere unokubalwa ngokusekelwe kumahluko phakathi komgangatho wegolide-isilivere edibeneyo edibeneyo kunye nomgangatho wegolide.


Emva kokuba indlela yokuvavanya umlilo igqibe ukwahlukana kunye nokutyetyiswa kwegolide, isilivere kunye nesinyithi esixabisekileyo, ukongeza kwindlela ye-gravi metric ekhankanywe ngasentla yokumisela igolide nesilivere, emva kokunyibilika amasuntswana egolide nesilivere nge-aqua regia, uhlalutyo lweekhemikhali ezahlukeneyo. iindlela zingasetyenziselwa ukumisela igolide, isilivere kunye nezinye iintsimbi ezixabisekileyo.
