I-CMC isebenzisa embonini yezimayini

I-sodium carboxymethyl cellulose isetshenziswa njenge-pellet binder kanye ne-flotation inhibitor embonini yezimayini. I-CMC iyimpahla eluhlaza yokwenza i-ore powder form binder. I-binder iyisici esibalulekile ekwenzeni ama-pellets. Thuthukisa izici zebhola elimanzi, ibhola elomile namapellets agazingiwe, abe nokuhlangana okuhle kanye nezakhiwo zokwakha amabhola, ibhola eliluhlaza elikhiqiziwe linokusebenza okuhle kokulwa nokungqongqoza, ukucindezelwa okuphezulu kwebhola elomile nelimanzi namandla okuwisa, futhi ngesikhathi esifanayo Lingakwazi thuthukisa izinga lama-pellets. I-CMC futhi iyisilawuli kunqubo yokuntanta. Isetshenziswa kakhulu njenge-silicate gangue inhibitor, ekuhlukaniseni ithusi nomthofu, futhi ngezinye izikhathi isetshenziswa njenge-dispersant ye-sludge.

Dindlela yokukhipha

Xuba i-CMC ngqo namanzi ukuze wenze unama. Ekucushweni kweglue ye-CMC, inani elithile lamanzi ahlanzekile lifakwa kuqala ethangini lokuxuba ngedivayisi yokuxuba. Ngaphansi kwesimo sokuvula idivayisi yokuxuba, i-CMC ihamba kancane futhi ihlakazeke ngokulinganayo ku-tank yokuxuba, futhi ihlale inyakaziswa, ukuze i-CMC namanzi kuhlanganiswe ngokugcwele futhi i-CMC ingaqedwa ngokugcwele. Lapho uncibilikisa i-CMC, isabalalise ngokulinganayo futhi uhlale uyinyakazisa ukuze uvimbele i-CMC ukuthi ingahlangani futhi ikhekhe uma ihlangana namanzi, futhi wehlise izinga lokuhlakazeka kwe-CMC. Isikhathi esinyakazayo kanye ne-CMC yokuncibilika ngokuphelele isikhathi azifani, ziyimiqondo emibili. Ngokuvamile, isikhathi esishukumisayo sifushane kakhulu kunesikhathi sokuchithwa kwe-CMC ngokuphelele, futhi isikhathi esidingwa yilaba ababili sincike esimweni esithile.

Isisekelo sokunquma isikhathi esinyakazayo siwukuthi lapho i-CMC ihlakazeka ngokulinganayo emanzini futhi ingekho into esobala enesigaxa esikhulu, ukunyakazisa kungamiswa futhi i-CMC namanzi kungangena futhi kuxubane komunye nomunye esimweni esimile.

Isikhathi esidingekayo sokuqedwa ngokuphelele kwe-CMC singanqunywa ngokusekelwe kulezi zici ezilandelayo:

(1) I-CMC iboshelwe ngokuphelele emanzini, futhi akukho ukwehlukana koketshezi oluqinile phakathi kwe-CMC namanzi;

(2) Iglue exubile isesimweni esifanayo, futhi ingaphezulu libushelelezi;

(3) Umbala we-aleurone exubile usondele kokungabi nambala futhi osobala, futhi ayikho into eyimbudumbudu ku-aleurone. Kuthatha phakathi kwamahora angu-1 nama-20 kusukela ngesikhathi i-CMC ifakwa ethangini lokuxuba futhi ixutshwe namanzi kuze kube yilapho i-CMC isihlakazwa ngokuphelele.

Izicelo ze-CMC Embonini Yezimayini

Ezimayini, i-CMC iyisengezo esingabizi kakhulu sokuthuthukisa amandla aluhlaza futhi sisetshenziswe njengesibophezelo enqubweni yokugaya insimbi yensimbi. Kuphinde kube isengezo esidingekayo sokuhlukanisa izingxenye zamaminerali ezibalulekile kumaminerali e-ganggue ngesikhathi senqubo yesine yokuntanta. I-CMC isetshenziswa njenge-adhesive ukuqinisekisa amandla amahle kakhulu aluhlaza ama-granules ngesikhathi sokukhiqiza. Isebenza njengesibophezelo sezinto eziphilayo ngesikhathi se-pelleting, imikhiqizo yethu isiza ukwehlisa okuqukethwe kwe-silica kunsimbi yensimbi ene-sintered. Ukumuncwa kwamanzi okuhle kakhulu nakho kuphumela emandleni aphezulu okuphinda abuyele emuva. I-CMC ingaphinde ithuthukise i-porosity ye-ore, ngaleyo ndlela ithuthukise ukusebenza kahle kwe-sintering. Imikhiqizo yethu ishiswa kalula ngesikhathi sokudubula, ingashiyi izinsalela eziyingozi futhi kungabikho miphumela emibi.

EyethuI-CMC yebanga lezimayiniimikhiqizo isetshenziswe njengama-inhibitors, ohlelweni lokuhlukanisa amaminerali amatshe angenalutho ezingxenyeni ezibalulekile ezintantayo. Kuyasiza ukunciphisa izindleko zamandla okusebenza kokuncibilika kanye nokwenza ngcono izinga lokugxilisa ingqondo, ekugcineni kuholele enqubweni yokuntanta engabizi kakhulu. I-CMC isiza inqubo yokuhlukanisa ngokucindezela izinto eziyigugu ze-ganggue. Umkhiqizo udala indawo engaphansi kwe-hydrophilic futhi wehlise ukungezwani kwendawo ukuze uvimbele amaminerali e-ganggue ukuthi anganamatheli kumabhamuza antantayo aqukethe amaminerali abalulekile e-hydrophobic.

Indlela yokufaka isicelo ye-CMC yebanga lezimayini:

I-CMC yebanga lezimayiniI-carboxymethyl cellulose ixubene ngqo namanzi, elungiselelwe uketshezi lokunamathisela lweglue, okubekwe eceleni. Ekucushweni kokunamathisela okunamathiselwe kwe-carboxymethyl cellulose, kuqala ngokuxuba izithako zesitshalo kusilinda ukuze kuhlanganiswe inani elithile lamanzi ahlanzekile, endaweni evulekile ngaphansi kwesimo sokunyakazisa,I-CMC yebanga lezimayinicarboxymethyl cellulose kancane futhi ngokulinganayo izithako isilinda, gqugquzela njalo, wenze Mining grade CMC carboxymethyl cellulose kanye amanzi ukuhlanganiswa isiyonke, Imayini grade CMC carboxymethyl cellulose ingancibilika ngokugcwele. Ekuhlakazweni kwe-carboxymethyl cellulose, isizathu sokusabalala ngokulinganayo, nokunyakazisa njalo, inhloso "ukuvimbela ukuhlangana kweMining grade CMC carboxymethyl cellulose kanye namanzi, i-agglomeration, agglomeration, ukunciphisa ukugcwala kwenkinga ye-carboxymethyl cellulose solubility", kanye thuthukisa izinga lokuqedwa kokugqoka kwe-carboxymethyl cellulose. Isikhathi esishukumisayo nokucutshungulwa kwamaminerali i-carboxymethyl cellulose isikhathi sokuqedwa okuphelele asihambisani, imiqondo emibili, ngokuvamile, isikhathi esishukumisayo sifushane kakhulu kunesikhathi esidingekayo sokuqedwa okuphelele kwe-carboxymethyl cellulose, isikhathi esidingekayo sincike esimweni esithile.

Okokuthutha kwesitoreji

Lo mkhiqizo kufanele ugcinwe ngokumelene nomswakama, umlilo kanye nezinga lokushisa eliphezulu, futhi kufanele ugcinwe endaweni eyomile nengenawo umoya.

Ubufakazi bemvula ngesikhathi sokuthutha, izingwegwe zensimbi zivinjelwe ngokuqinile ekulayisheni nasekuthululeni. Ukugcinwa kwesikhathi eside kanye nokucindezela kwenqwaba yalo mkhiqizo kungase kubangele ukuhlangana lapho ukhipha, okuzodala ukuphazamiseka kodwa ngeke kuphazamise ikhwalithi.

Umkhiqizo unqatshelwe ngokuphelele ukuthintana namanzi lapho ugcinwe, ngaphandle kwalokho uzobe ufakwe i-gelatinized noma uhlakazwe kancane, okuholela ekusetshenzisweni.
