Isanti yequartz ehlanjwe ngeasidi

Ukucholwa kwesanti yequartz kunye nenkqubo yokuchola icacisiwe

Ekukhethweni kwesanti ye-quartz ecocekileyo kunye nesanti ye-quartz ecocekileyo, kunzima ukuhlangabezana neemfuno zeendlela eziqhelekileyo ze-beneficiation, ngokukodwa kwifilimu ye-iron oxide ebusweni besanti ye-quartz kunye nokungcola kwentsimbi kwiintanda.Ukuze kuphuculwe ngcono umgangatho kunye nesivuno sokuhlanjululwa kwesanti ye-quartz, idibaniswe neempawu zesanti ye-quartz enganyibilikiyo kwi-asidi kunye ne-soluble kancinane kwisisombululo se-KOH, indlela yokucoca i-asidi ibe yindlela efunekayo yokuphatha isanti ye-quartz.

Unyango lokucholwa kwesanti yequartz kukunyanga isanti yequartz ngehydrochloric acid, sulfuric acid, oxalic acid okanye ihydrofluoric acid ukunyibilikisa intsimbi.

Inkqubo esisiseko ye-quartz pickling yesanti

I proportioning acid lotion

Iitoni zesanti kufuneka zenziwe nge-7-9% ye-oxalic acid, i-1-3% ye-hydrofluoric acid kunye ne-90% yomxube wamanzi;Idinga iitoni ezi-2-3.5 zamanzi, ukuba amanzi ahlaziywa kwakhona, ngoko kuphela iitoni ezi-0.1 zamanzi ezifunekayo ukucoca itoni yesanti, kumsebenzi wokucoca isanti, ngokuqinisekileyo uya kuzisa ininzi yesanti;Unyango lokucholwa kwesanti yequartz kukunyanga isanti yequartz ngehydrochloric acid, sulfuric acid, oxalic acid okanye ihydrofluoric acid ukunyibilikisa intsimbi.

Ⅱ Umxube wokukha

Isisombululo se-pickling sifakwe kwi-pickling tank kwaye yongezwa ngokomlinganiselo we-hydrochloric acid content malunga ne-5% yobunzima besanti ukuqinisekisa ukuba isanti ye-quartz ifakwe kwisisombululo sokukha kunye nomxholo we-hydrochloric acid malunga ne-5% ubunzima besanti.

Ⅲ Isanti yequartz ehlanjwe ngeasidi
① Ixesha lokuba isanti yequartz ifunxe isisombululo sokuchola ngokuqhelekileyo ziiyure ezi-3-5, isidingo esikhethekileyo sokunyusa okanye ukunciphisa ixesha lokucwina ngokolusu olutyheli lwesanti yequartz, okanye isisombululo sokuchola kunye nesanti yequartz inokushukunyiswa kangangexesha elithile. ixesha, elilandelwa kukusetyenziswa kwezixhobo zokufudumeza ukufudumeza isisombululo kwiqondo elithile lobushushu, kunokunciphisa ixesha lokukhetha.

② Ukusetyenziswa kwe-oxalic acid kunye ne-alum eluhlaza njengokunciphisa i-agent yonyango yokucoca kunokuphucula ukunyibilika kwesinyithi, emva koko, amanzi, i-oxalic acid, i-alum eluhlaza ngokuhambelana nomlinganiselo wesisombululo kubushushu obuthile, isanti yequartz kunye nesisombululo kunye nomlinganiselo othile wokuxuba, ukuvuselela, unyango lwemizuzu embalwa, isisombululo siyahluzwa kwaye siphathwe emva kokubuyisela.

③ Unyango lwe-Hydrofluoric acid: Isiphumo silungile xa unyango lwe-hydrofluoric acid lusetyenziswa lodwa, kodwa ugxininiso luphezulu.Xa kwabelwana nge-sodium dithionite, i-concentration ephantsi ye-hydrofluoric acid ingasetyenziswa.

Uxinzelelo oluthile lwe-hydrochloric acid kunye nesisombululo se-hydrofluoric acid saxutywa kwi-quartz sand slurry ngexesha elifanayo ngokwemilinganiselo;Inokuphinda iphathwe ngesisombululo se-hydrochloric acid kuqala, ihlanjwe kwaye iphathwe nge-hydrofluoric acid, iphathwe kwiqondo lokushisa eliphezulu kwiiyure ezingama-2-3, kwaye ihlulwe kwaye ihlambuluke.

Phawula:

Ukuba i-hydrofluoric acid isetyenziselwa i-acid soak isanti ye-quartz, ukusabela kuyinkimbinkimbi.Ukongeza kokuchithwa kwesinyithi kwimidiya ye-acidic, i-HF inokuphinda iphendule nge-quartz ngokwayo ukuze ichithe i-SiO2 kunye nezinye i-silicates zobunzima obuthile phezu komhlaba.

Nangona kunjalo, oku kusebenza ngakumbi ekucoceni umphezulu wesanti ye-quartz kunye nokuphelisa isinyithi kunye nolunye ungcoliseko lokungcola, ngoko ke i-hydrofluoric acid ilungile kwi-acid leaching ye-quartz.Nangona kunjalo, i-HF iyityhefu kwaye inomhlwa kakhulu, ngoko ke iasidi ekhupha amanzi amdaka ifuna unyango olukhethekileyo.

iv Ukuchacha kwe-Acid kunye nokuncipha kweasidi

Hlanza isanti yequartz ehlanjwe nge-asidi ngamanzi amaxesha angama-2-3, kwaye emva koko ungathathi hlangothi nge-0.05% -0.5% yesisombululo sealkaline yesodium (caustic soda), kwaye ixesha lokungathathi hlangothi limalunga nemizuzu engama-30-60, kwaye uqinisekise ukuba yonke iquartz. isanti ayithathwanga ndawo.Xa i-pH ifikelela kwi-alkaline, unokukhulula i-lye kwaye uhlambulule amaxesha angama-1-2 de i-pH ingathathi hlangothi.

Ⅴ Isanti yequartz eyomileyo

Isanti ye-quartz kufuneka ikhutshwe ngamanzi emva kokurhoxiswa kwe-asidi, kwaye ke isanti ye-quartz kufuneka yomiswe kwisixhobo sokumisa.

Ⅵ ukuhlolwa, ukukhetha umbala kunye nokupakishwa, njl.

Oku ngasentla yinkqubo esisiseko yokucholwa kwesanti ye-quartz kunye nenkqubo yokucoca isanti, i-quartz ore yesanti inosasazo olubanzi kwilizwe lethu, ngoko ke kukho umahluko kubume besanti ye-quartz, ekucoceni isanti yequartz nayo ifuna iingxaki ezithile. uhlalutyo, ukuphuhlisa inkqubo efanelekileyo yokucoca isanti ye-quartz.
