Ukufunda Okuhlobene

1.Izinqubo ezimbili zokukhiqiza ze-sodium pyrosulfite: inqubo eyomile nenqubo emanzi:

1. Inqubo eyomile : gudluza umlotha wesoda namanzi ngokulinganayo ngokwesilinganiso esithile se-molar, bese uwafaka ku-reactor lapho i-Na2CO3.I-nH2O eyenziwe isesimweni samabhulokhi, gcina igebe elithile phakathi kwamabhulokhi, bese wengeza i-SO2 kuze kuqedwe ukusabela, khipha amabhlogo, futhi uwachoboze ukuze uthole umkhiqizo oqediwe.

2. Inqubo emanzi : engeza inani elithile le-soda ash kusisombululo se-sodium bisulfite ukuze wenze ukumiswa kwe-sodium bisulfite, bese ufaka i-SO2 ukuze wenze amakristalu e-sodium pyrosulfite, afakwe i-centrifuged futhi omisiwe ukuze athole umkhiqizo ophelile.

I-2.Inqubo yendabuko emanzi ye-sodium pyrosulfite enesulfure njengento eluhlaza

Okokuqala, gxoba isibabule sibe yimpushana, bese uthumela umoya ocindezelwe esithandweni somlilo esingu-600~800 ℃ ukuze sivuthe.Inani lomoya elingeziwe licishe liphindwe kabili inani lethiyori, futhi ukugxila kwe-SO2 kugesi kungu-10~13.Ngemuva kokupholisa, ukususwa kothuli nokuhlunga, isibabule esine-sublimated nokunye ukungcola kuyasuswa, futhi izinga lokushisa legesi liyehla libe ngu-0 ℃, ukusuka kwesokunxele kuye kwesokudla, bese lithunyelwa ku-reactor yochungechunge.

Kancane kancane engeza utshwala obumama nesisombululo somlotha wesoda esikhunjeni sesithathu ukuze uthole ukusabela kokungathathi hlangothi.Ifomula yokusabela imi kanje:

2NaHSO4+ Na2CO3→ 2 Na2SO4+ CO2+ H2O

Ukumiswa kwe-sodium sulfite okukhiqiziwe kudluliselwa ku-reactors yesigaba sesibili nesokuqala ngokushintshana, bese kudonswa futhi kusabelane ne-SO2 ukuze kukhiqizwe ikristalu ye-sodium pyrosulfite.

3.Isingeniso ku-Sodium Metabisulfite ekusetshenzisweni kokucubungula amaminerali ensimbi

I-Sodium Metabisulfite isetshenziswa kabanzi embonini yezimayini.Izindlela zokucubungula amaminerali zimi kanje:

I-Flotation: I-Flotation yindlela yokuhlukanisa amaminerali awusizo ku-ore, ngokusekelwe ezintweni ezibonakalayo namakhemikhali ezinhlayiya zamaminerali.Cishe yonke insimbi ingasetshenziswa ekuhlukaniseni i-flotation.

Ama-reagents e-Flotation avame ukusetshenziswa ekuntanteni: umqoqi, i-ejenti ekhipha amagwebu, isilungisi.Phakathi kwazo, i-modifier ihlanganisa i-inhibitor, i-activator, i-ejenti yokulungisa i-pH, i-ejenti ehlakazayo, i-flocculant, njll.

I-ejenti yokubamba: I-ejenti yokubamba ama-reagents e-flotation ashintsha i-hydrophobicity ye-mineral surface, yenza izinhlayiya ze-planktonic mineral zinamathele kubhamuza.I-Xanthate, i-powder emnyama ingumqoqi we-anionic.

Ukuntanta komthofu kanye ne-zinc ores

I-Galena (okungukuthi i-PBS) iyiminerali evamile, iwuhlobo lwe-sulfide.I-Xanthate ne-powder emnyama ivame ukusetshenziswa njenge-ejenti yokubamba (i-potassium dichromate iyi-inhibitor ephumelelayo).

I-Sphalerite (ZnS) ukwakheka kwamakhemikhali amaminerali e-sulfide afana ne-ZnS, Amakristalu.

Umthamo wokubamba weketango elifushane i-alkyl xanthate ku-sphalerite ibuthakathaka noma ayitholakali.I-ZnS noma i-Marmatite ngaphandle kokwenza kusebenze ingakhethwa kuphela ngochungechunge olude lohlobo lwe-xanthate.

Esikhathini esilandelayo, izicelo zama-ejenti wokubamba i-xanthate zizoqhubeka nokuhlala esikhundleni esiphezulu.Ukuze uvumelane nesidingo sokuntanta okuyinkimbinkimbi kwe-Sphalerite, inhlanganisela yekhemisi ibalulekile, futhi kuyindlela ephumelelayo yokuthepha ngokugcwele amandla emithi yendabuko.

I-flotation inhibitor eyinhloko imi kanje:

1. Umcako (i-CaO) unokumunca amanzi okuqinile, usebenza ngamanzi ukuze ukhiqize umcako we-hydrated Ca(OH)2.I-lime isetshenziselwa ukwenza ngcono i-pH ye-pulp, inhibit of iron sulfide minerals.Ku-sulfide yethusi, i-lead, i-zinc ore, evame ukuhlotshaniswa ne-sulfide iron ore.

2. I-Cyanide (KCN, NaCN) iyisivimbeli esisebenzayo sokuhlukaniswa komthofu ne-zinc.Ku-pulp ye-alkali, ukugxila kwe-CN kuyanda, okuhambisana nokuvinjelwa.

3. I-Sterling ye-Zinc Sulfate iyikristalu emhlophe, encibilika emanzini, iyi-inhibitor ye-sphalerite, ngokuvamile ku-pulp ye-alkali inomphumela wokuvinjelwa.

4. Ukhiye odlala izindima zokuvimbela ku-sulfite, i-sulfite, i-SO2 ngokuyinhloko i-HSO3－.I-Sulfur dioxide ne-sub sulfuric acid (usawoti) isetshenziswa kakhulu ekuvimbeleni i-Pyrite ne-sphalerite.I-acid mine pulp ebuthaka eyenziwe nge-lime evela ku-Sulfur dioxide (pH=5～7), noma sebenzisa i-Sulfur dioxide, i-zinc sulfate, i-ferrous sulfate ne-ferric sulfate ndawonye njengesivimbeli.Ngakho-ke i-galena, i-pyrite, i-sphalerite ivinjelwe.I-sphalerite evinjelwe ingenziwa isebenze ngenani elincane le-sulfate yethusi.Futhi ingasebenzisa i-Sodium thiosulfate, i-sodium metabisulfite esikhundleni se-sulfite, ukuvimbela i-sphalerite ne-iron pyrites (eyaziwa kakhulu ngokuthi i-FeS2).
