Ukwenzela ukuphucula ukukhetha inkqubo yokuqhutywa, ukuphucula iziphumo zabaqokeleli, ukunciphisa ukuqhutywa kwezimilo eziluncedo, kwaye kuphuculwe iimeko zeflourtos, ezilawulayo zihlala zisetyenziswa kwinkqubo yokufuduswa. Abavumisi kwinkqubo yokufuduselwa baquka iichemicals ezininzi. Ngokwendima yabo kwinkqubo yokufuduselwa, banokwahlulwa babe yi-inhibitors, abavumeli abaphambili, iiarhente ezidayo, ii-ages ezidangeleyo, ii-intercys, abantu banokuthintela i-adsen okanye isenzo se Umqokeleli kumphezulu weemineranzi ezingezizo-dayali, kwaye wenze ifilimu ye-hydrophilic kumphezulu weeminerals. I-Sodium ye-Oxide ye-Oxide yenye yezona ndawo zibalulekileyo kwinkqubo yeflethi yeqabaka.
Injani i-sodium ye-oxdium
Umgaqo osisiseko sokusetyenziswa kwe-sodium oxide (na2o) njenge-inhibitor ngefloti yeminerali ibandakanya iipropathi zekhemikhali kunye nokusebenzisana nomhlaba weemineral. Eli nqaku liza kuzisa ngokweenkcukacha isakhiwo semolekyuli, ifomula yekhemikhali, impendulo yekhemikhali kunye nendlela yothintelo. Imo yemolekyuli kunye nefomula yekhemizi lekhemikhali ye-sodium oxide yi-na2o, eyindawo edityanisiweyo ye-ions ye-sodium (na ^ +) kunye neoksijini (o ^ 2-). Kwibhotso lemineral, umsebenzi ophambili we-sodium oxide ukuba usabele nge-calic kunye ne-oxygen yayo kwindawo yeminerali, ngaloo ndlela ukutshintsha iipropathi zomphezulu weminerali kunye nokuvula iflethi yezimbiwa ezithile. Isicelo kunye nomgaqo-nkqubo we-sodium oxide kwiflowa lemineral
I-1. Ukuphendula kwe-Oxidation kwi-Mineral Flotation, iSodium Oxide ingena kwimpendulo ye-oxidation kunye nomphezulu weeminerals ezithile. Le meko idla ngokuquka i-sodium yesigusha okanye i-hydroxides kumphezulu weminerali ivelise imingxunya okanye i-formating versing ethintela ifloral. Umzekelo, kumgangatho wentsimbi yentsimbi (njenge-fe2o3 okanye fe (oh), i-oodium oxide i-oxide oxide oxide, i-fe2o3 okanye i-2NA2O + 3 → I-2NOFOIO2 + le ndlela ye-3H2O ibangela ukuba umphezulu weeminerals zentsimbi ukuba igqunywe nge-sodium yentsimbi, ngaloo ndlela Ukunciphisa umthamo we-adsorction ngearhente zentyatyambo (njengabaqokeleli), ukunciphisa ukusebenza kwayo, kunye nokufezekisa intsasazo yentsimbi yentsimbi. I-2. I-PH yohlengahlengiso ukongezwa kwe-sodium oxide nayo inokulungelelanisa ixabiso le-pH inkqubo yefloti. Ngamanye amaxesha, ukutshintsha i-PH yesisombululo kunokuchaphazela iimpawu kunye neempawu zekhemikhali zomphezulu wezimbiwa, ngaloo ndlela kuchaphazela ukukhetha amaminerali ngexesha lokukhetha. Umzekelo, kwiflethi yeeminerali zobhedu, iimeko ezifanelekileyo zibaluleke kakhulu ukuthintela iflethi yeemineraling. 3. Ukukhetha ukukhetha i-Musings yefuthe lezinto ezithintelweyo ze-sodium goaside idla ngokuba nenqanaba elithile lokukhetha kwaye inokufezekisa isiphumo sokuthintela kwizimbiwa ezithile. Umzekelo, i-infinitshala yeeminerali zentsimbi isebenza ngakumbi kuba ukusabela phakathi kweSodium Oxide kwaye umphezulu weeminerals zentsimbi unamandla, kwaye i-sodium yentsimbi yenziwe inokusithintela ukusebenzisana kwayo nge-arhente yonxibelelwano. 4. IMIQATHANGO EYAFUMANEKA KWENKQUBO YOKUZIPHATHA KWENKQUBO YOKUZIPHATHA NGOKUFUMANELEKILEYO NGOKUFUMANELEKILEYO KWIMININQAKU EXELELEYO iimeko zokusebenza kwinkqubo yeflotition. Ezi zinto zisebenza kunye ukufumanisa isiphumo sothintelo kunye nokufaneleka kwe-sodium oxide kwinkqubo ethile yeflotation. ISISHWANKATHELO NOKUFUNDA Indlela yayo yesenzo ibandakanya ukuphendula okuphezulu, i-PH yohlengahlengiso kunye nefuthe kwizimbiwa zemichiza. Ngophando oluqhubekayo olunzulu kwithiyori yezimbiwa zethambo kunye netekhnoloji, ukusetyenziswa kwe-oxide kunye nezinye izinto ziya kuba zichanekile kwaye zisebenze ngokufanelekileyo kunye nezisombululo zeshishini leminerali. Oku kudityaniswa kwethiyori kunye nokuziqhelanisa kubonelela ngeenjineli ezifuyo kunye nabaphandi ngethuba lokuqonda ngokunzulu kwaye basebenzise i-inhibitors yokuqinisekisa ukubuyiswa kwezixhobo kunye nomgangatho wemveliso.
Ukusetyenziswa kwe-sodium ye-sodium ye-oxide
Xa uthetha malunga netyala lesicelo le-sodium oxide njengendawo eneflotional i-inftion, inokubonwa ukuba idlala indima ebalulekileyo ekuqhubeni iintlobo ezahlukeneyo ze-ores. Oku kulandelayo ziimeko ezithile zesicelo: 1. Isicelo kwi-iron ore ye-iron ore i-ore i-ore i-ore inee-oxibes, kubandakanya ii-oxis zentsimbi (njenge-hematite, imagnetite) kunye nentsimbi yentsimbi. Izinto (ezinjenge-PYBI). Kwinkqubo yefloti yentsimbi, xa iyimfuneko ekuphuculeni izinga lokubuyiswa kwezinyithi ezingengabi, i-sodium oxide inokusetyenziswa njenge-inhibitorating minessi. Umzekelo, xa i-oresper yobhedu equkethe i-Iron Sulfides, i-Sodium Oxide ikwazisa ngee-oxis okanye i-hydroxides kumphezulu we-Iron Sulfides, ngokuthintela ukubuyiselwa kobhedu. Ixabiso liphuculwe. 2. Isicelo kwiflestation ye-Copper-nchest ore kwinkqubo ye-copper-finc ore, idla ngokunethemba lokuphucula umgangatho wokubuyiselwa kobhedu ngelixa unqanda i-zinc. Kule meko, i-sodium yesoside inakho ukulungisa iimeko zenkqubo yefloti ngokuhlengahlengisa ixabiso le-pH yesisombululo, ukuze i-PH i-PH inqanaba le-PH, isodium oxide lingayithinteli iflocys minersi, ngaloo ndlela inyusa umgangatho wokubuyiselwa kobhedu kunye nenqanaba. 3. Isicelo kwiflotition ye-Collec-chinc sulfide ore-chinc sulfide ore idla ngokuhamba kunye ne-iron iminemi yentsimbi iya kuchaphazela isiphumo sokukhokelela kunye ne-zinc. Kunyango lwe-Cound-chinc sulfide ore, i-sodium oxide ingenza isigqubuthelo okanye itshintshe imeko ye-ntlawulo ye-filling kunye nomphezulu weeminerals zentsimbi kunye ne-zinc . I-4. Ukusetyenziswa kwe-phosphate yezimbiwa kwiflotity phosphate minerals (ezinjenge-Apatite, i-calcium phosphate ore, ngaphandle kwe-ores, ubukho bezinye iinyibiba. Iflethi inefuthe. I-Sodium Oxide inokusetyenziswa njenge-inhibitor kule meko, ngokuhlengahlengisa ixabiso le-pH yenkqubo okanye ngokuthe ngqo ne-phostor ye-phosphate ukunciphisa ukusebenzisana okanye ukunyusa ukugxila kwezinye izinyithi ezithile (ezinje Ubhedu, i-nickel, njl. Njl. I-5. Ukusetyenziswa kwee-minerals ze-silcoate kwi-fulticate amanerals (ezinjenge-ranz, i-feldspar, njl njl) zihlala zichaphazela izimbiwa ze-ores, kodwa zinokuchaphazela iiminerali zentsimbi (ezinje ngobhedu, i-zinc, kukhokelela , njl.)) Impembelelo yeflotion. I-sodiumsium oxide inokunciphisa i-adsorvo yokhuphiswano yearhente yokucoca ngokuhlengahlengiswa kwexabiso lesisombululo okanye ukusabela ngokusasaza kunye nenqanaba lokubuyisela kwimeko yesiqhelo kunye nenqanaba leminerals.
