Inkqubo esetyenziswayo yemigaqo esetyenziswayo esetyenziswayo yokuqhutywa kwe-istide ye-chinc ye-chinc sulfide ibandakanya ukucutha okuthatha kuqala, iflotation exubeneyo kunye neflotation efanayo.
Nokuba yeyiphi na inkqubo esetyenzisiweyo, uyakuhlangabezana neengxaki zokukhokela - i-zinc yokwahlula kunye ne-zinc-sulfur yokwahlulahlula. Isitshixo sokwahlulahlulwa sisiseko sokukhetha esifanelekileyo sonyulo.
Kuba ukwenziwa kweenjongo ze-galena kungcono kuneso seShalerite, zonke iindlela zokucinezela i-zinc kwaye zikhokele ukuntywila zisetyenziswa. Isisombululo samayeza sokuthintela i-zinc kubandakanya indlela yeCynide kunye nendlela yasimahla yeCynide. Kwindlela ye-cyadade, i-hinc slilfate ihlala isetyenziswa ngokudibeneyo ne-cynide ukonyusa isiphumo esiyinyani. Umzekelo, isityalo esithile sisebenzisa i-sodium cyfake kunye ne-zinc sulfate kwindibaniselwano yokunciphisa umthamo we-20 ~ 30G / T, kwaye abanye bade banciphise ukuya kwi-3 ~ 5g / t. Ukuziqhelanisa kungqiniwe ukuba akunciphisi idosi, kodwa kwandisa izinga lokubuyisela kwimeko yesiqhelo lokukhokela.
Ukwenzela ukuthintela ungcoliseko lwe-cynide kwindalo, iCynide-Free okanye iindlela ezincinci-ezincinci zikhuthazwe ekhaya nakwamanye amazwe. Iindlela ezifumanekayo ezilandelayo zeCyAnide zihlala zisetyenziswa kwishishini lokukhokela kunye ne-zinc yahlulahlulahlulahlulahlulahlulahlulahlulahlulahlula
I-1. Ukukhokelela kwe-winc
.
I-Cound-chinc-sulfur i-yam yamkela inkqubo yokhetho olukhethiweyo. ZNNSO4 + NA2CO3 (1.4: 1) yayisetyenziselwa ukucinezela i-splalerite xa ikhokelwa. Xa kuthelekiswa nendlela ye-cyade, ibakala elihambelanayo eligxile kwi-39.12% ukuya kwi-41.80% ukuya kwiBanga leZinc ukuvela kwi-78.5.60% ukuya kwi-48.43%, kunye ne Izinga lokubuyisela kwimeko yesiqhelo linyuke ukusuka kwi-88.54% ukuya kwi-90.03%.
(2) i-zinc supelfate + isalfi;
(3) I-Zinc supelfate + inyibiliki;
(4) i-sodium hydroxide (PH = 9.5, eqokelelene nomgubo omnyama);
(5) sebenzisa i-zinc sulfate yedwa ukuba inyule i-zinc;
(6) Sebenzisa igesi ye-SO2 ukucinezela i-zinc.
I-2. I-hinc ye-winc ikhokela
(1) i-lime;
(2) iglasi yamanzi;
(3) Iglasi yamanzi + i-sodium hulfide.
Ezi ndlela zintathu ezingentla zisetyenziswa xa iGalena i-oxid bed kunye neentyatyambo zayo ziyahlwempuzeka.
Ukukhokela okudadayo, amayeza amnyama kunye neXntanthate kuhlala kusetyenziswa njengabaqokeleli, okanye i-ithyl sulfide bodwa ngokukhetha okuhle kusetyenziswa njengomqokeleli. Ezinye izityalo ezisebenzayo zangaphandle zidibanisa i-Sulfosucinic Acid (A-22) ngeXanthate.
Kuba i-lime inesiphumo esinemibuzo kwiGalena, xa kukho iPyrite encinci kwi-Ore, iluncedo ngakumbi ukusebenzisa i-sodium carbonate njengoMthetho we-PH. Xa umxholo we-Pyrite kwi-ore ore ore up up, kungcono ukusebenzisa i-lime njengoMthetho we-PH. Kuba i-lime inokuthintela i-pyrite ehambelana nayo, kuyingenelo ukuba ikhokele.
Ukuvusa i-splaleritar usebenzisa i-calper yobhedu. Ukwenzela ukuphepha i-calfate ye-calfate kunye ne-xenthate eyakha ibhetri kwi-XATHATE ngexesha lenkqubo yokuxuba i-slide kunye nokunciphisa ukusebenza kwearhente yearhente yongezwa ngokubanzi, kwaye emva koko iXanthate yongezwa emva kokuvuselela imizuzu emi-3 ukuya kwezi-5.
Xa kukho iindawo ezimbini ekulula ukuntywila kwaye ezo kunzima ukuzibhabha kwi-schalerite, ukuze zigcine iikhemikhali kunye nokuphucula isalathiso sokukhokela kunye ne-zinc, inkqubo enokuphinda ikhule kwaye iqhuba kakhulu kunye ne-zinc.
I-3.Method ye-zinc kunye ne-sulfur yokwahlulahlula
(1) I-hinc edadayo icinezela i-sulfur
I-1. Indlela ye-lime
Le yeyona ndlela isetyenziswayo yokucinezelwa. Le ndlela ingasetyenziselwa ukuqhubekisa i-ore ore ye-ore kunye ne-winc-sulfur ixube igxile. Xa usebenzisa le ndlela, sebenzisa ikalika ukuze uhlengahlengise i-PH, ngesiqhelo ngaphezulu kwe-11, ukuze i-PGIT icinezelwe. Le ndlela ilula, kwaye ikhemikhali esetyenzisiweyo yi-lime, enexabiso eliphantsi kwaye kulula ukuyifumana. Nangona kunjalo, ukusetyenziswa kwekalika kunokubangela ukutywina kwezixhobo zokuvutha, ngakumbi imibhobho, kwaye i-Sulfure igxile ekungasebenziyo kukucoca, kukhokelela ekwenzeni umswakama ophezulu.
Indlela yokujonga
Kwezinye iip'etes ngomsebenzi ophezulu wePlasskotonic, ukucinezelwa yindlela ye-lime kuhlala kungasebenzi. Xa ifudula ifudumele i-slarry, iidigri ze-oxidation ze-schalerite kunye ne-pyrite zahlukile. Emva kokuba i-winc-sulfure ixutywe ngokugxininisayo ishushu, i-ared baxhunyiwe, ishukumisekile, ukwenziwa kwe-pigrite yeyokuhla, ngelixa ukwenziwa kwe-schalerite.
Uphando lubonisa ukuba i-zinc kunye ne-sulfure inokwahlulwa ngokufudumeza i-steam yokwahlulahlula i-zinc-sulfure ixutywe. Iqondo lobushushu le-Coardes yi-42 ° 4,3 ° C, kunye nokwahlula okuhle ngaphandle kokufudumeza okanye ukongeza nayiphi na imichiza ingahlukanisa i-zinc kunye nesalfure. Isalathiso esifunyenweyo yi-6.2% ephezulu kune-chinc igxilwe ekwindlela ye-LAM, kwaye iqondo lokubuyisela kwimeko yesiqhelo liphezulu.
3. I-LIM
Xa i-lime yodwa ayinakukwazi ukusebenza kakuhle i-iron inyibiliki, yongeza inani elincinci le-cyanide (umzekelo: I-Nacn5g / T kwi-Hisn Right) ukuphucula ukwahlulwa kwe-zinc-sulfur.
(2) I-Sulfur edadayo icinezela i-zinc
I-Sulfur Dioxide + Indlela yokufudumeza i-Steam Le ndlela isetyenziswe kwi-brunswick isityalo se-runswick kwiCanada. I-zinc igxile ekufumaneni isityalo iqulethe i-pyrite eninzi. Ukwenzela ukuphucula umgangatho, i-slickry iphathwa ngegesi ye-sulfur diokside kwaye ifudumele i-steam ukucinezela i-zinc kunye ne-darfur yesalfur.
Indlela ethile kukuzisa i-sulfur dioxide irhasi evela emazantsi etanki yokuqala eshukumisayo kunye nolawulo lwe-PH = 4.5 ukuya ku-4.8. I-Steam Steam kwitanki yesibini neyesithathu kwaye itshise ukuya kuthi ga kwi-77 ° 8 ° C. Xa uqhwithela iPyrite, i-PH i-5.0 ~ 5.3, kwaye iXntanthate isetyenziswa njengomququzeleli. Imisipha yeflotiotion yi-zulc yokugqibela igxile. Ukongeza kwi-PYBIT, imveliso ye-foam nayo iqulethe i-zinc. Emva kokukhethwa, isetyenziswa njenge-ore ephakathi kwaye ibuyiselwe kwi-ore ephakathi phambi kwenkqubo yokubuyisa kwakhona. Ulawulo oluchanekileyo lwe-pH kunye neqondo lobushushu sisitshixo kule nkqubo. Emva konyango, imveliso ye-zinc igxile kwi-50% ukuya kwi-51% ye-zinc ukuya kwi-57% ukuya kwi-58%.
