Izakhiwo zamaminerali kanye nesakhiwo samaminerali
Amaminerali aqukethe i-Titanium ikakhulukazi ahlanganisa i-ilmenite, i-rutile, i-anatase, i-brookite, i-perovskite, i-sphene, i-titanomagnetite, njll., phakathi kwayo i-ilmenite ne-rutile okungamaminerali ayinhloko okuncibilikisa i-titanium.
Ifomula yamangqamuzana e-ilmenite ithi FeTiO3, ngokombono equkethe u-52.66% we-TiO2 kanye no-47.34% we-FeO. Kuyinsimbi empunga kuya kwensimbi emnyama, enobulukhuni be-Mohs obungu-5-6, ukuminyana okungu-4.72g/cm3, uzibuthe omaphakathi, umqhubi omuhle, nohlobo oluvamile. Ubunikazi bekhwalithi buxubene ne-magnesium ne-manganese, noma iqukethe i-scaly hematite inclusions.
I-molecular formula of rutile ithi i-TiO2, equkethe u-60% Ti kanye no-40% O. Iyiminerali ebomvu ngokunsundu, evamise ukuqukatha ingxube yensimbi, i-niobium, i-chromium, i-tantalum, ithini, njll., enobulukhuni be-Mohs obungu-6, kanye nokuminyana okungu-4.2~4.3g/cm3. I-Magnetism, i-conductivity enhle, insundu emnyama uma okuqukethwe kwensimbi kuphezulu, i-rutile ikhiqizwa ikakhulukazi kuma-placers.
Izinkambu zohlelo lokusebenza kanye nezinkomba zobuchwepheshe
I-Rutile kanye ne-ilmenite yizinto zokusetshenziswa eziyinhloko zokuncibilikisa i-titanium yensimbi, ukukhiqiza i-titanium dioxide, izinduku zokushisela, kanye nezinsimbi zokushisela.
Ithebula 1. Ukusetshenziswa okuyinhloko kwe-rutile ne-ilmenite
Ithebula 2. I-Titanium Concentrate Quality Standard
Ithebula 3. Amazinga Ekhwalithi Yoku Rutile Kwemvelo
Ukucubungula ubuchwepheshe
Ngokuvamile i-ilmenite ne-rutile ore ihambisana nezinhlobonhlobo zamanye amaminerali, njenge-magnetite, i-hematite, i-quartz, i-feldspar, i-amphibole, i-olivine, i-garnet, i-chromite, i-apatite, i-mica, i-pyroxene Stones, njll., ngokuvamile ikhethwa ngokuhlukaniswa kwamandla adonsela phansi, kazibuthe. ukuhlukaniswa, ukuhlukaniswa kukagesi kanye nokuntanta.
Ukuzuza amandla adonsela phansi
Le ndlela ivamise ukusetshenziselwa ukuhlukanisa kabi indawo equkethe i-titanium noma i-titanium egayiwe eyisisekelo. Ukuminyana kwamaminerali aqukethe i-titanium ngokuvamile kukhulu kuno-4g/cm3. Ngakho-ke, ama-ganges amaningi anesisindo esingaphansi kuka-3g/cm3 angasuswa ngokuhlukaniswa kwamandla adonsela phansi. Ukususwa kwamaminerali. Imishini yokuhlukanisa amandla adonsela phansi ihlanganisa i-jig, i-spiral concentrator, i-shaker, i-chute, njll.
Ukuhlukaniswa kwamagnetic
Indlela yokuhlukanisa kazibuthe isetshenziswa kakhulu ekukhetheni amaminerali aqukethe i-titanium. Singasebenzisa ukuhlukaniswa kukazibuthe okubuthakathaka ukuhlukanisa i-magnetite, bese sisebenzisa ukuhlukaniswa kukazibuthe okuqinile ukuhlukanisa i-ilmenite yamagnetic emaphakathi. Isibonelo, i-concentrate iqukethe i-iron oxide eyengeziwe noma I-silicate yensimbi, indlela yokuhlukanisa amandla adonsela phansi kufanele isetshenziselwe ukususa ukungcola nge-gravity encane ethize. Embonini, kusetshenziswa kokubili ukuhlukaniswa kozibuthe okomile nokumanzi.Imishini yokuhlukanisa kazibuthe ikakhulukazi ihlanganisa isihlukanisi esiyisilinda kazibuthe, isihlukanisi sikazibuthe sepuleti, indandatho eqondile eyindandatho ephakeme ye-gradient isihlukanisi kazibuthe, njll.
Isihlukanisi kazibuthe sesigubhu
Isihlukanisi esinozibuthe esinamandla amakhulu
Ukuhlomula kwe-Electrostatic
Ikakhulu isebenzisa umehluko we-conductivity phakathi kwamaminerali ahlukene ekugxilweni okuqinile okuqukethe i-titanium ukuze kukhethwe, njengokuhlukaniswa kwe-rutile, i-zircon, ne-monazite. Izihlukanisi zikagesi ezisetshenziswayo uhlobo lwe-roller, uhlobo lwepuleti, uhlobo lwepuleti lesisefo nokunye.
Ukuntanta
Isetshenziswa kakhulu ukuhlukanisa insimbi ene-titanium ecolekile. Ama-reagents e-flotation avame ukusetshenziswa ahlanganisa i-sulfuric acid, amafutha omude, i-oleic acid, i-diesel oil kanye nama-emulsifiers. Izindlela zokuzuza zihlanganisa ukuntanta okuhle kwe-titanium kanye nokuhlehla kwe-amineral gangue.
Ukuzuza ngokuhlanganyela
Nge-placerite enamaminerali ahlotshaniswa kakhulu, umehluko ekuthambekeni kazibuthe okuqondile, ukuminyana, ukuhamba kahle, kanye nokuntanta phakathi kwamaminerali ungasetshenziswa ukuhlukanisa amaminerali ngenqubo ehlanganisiwe “yezibuthe, ezisindayo, zikagesi, kanye nokuntanta”.Ngokwesibonelo, ugu lolwandle isihlabathi se-alluvial siqukethe amaminerali afana ne-magnetite, i-ilmenite, i-rutile, i-zircon sand, i-monazite, isihlabathi solwandle, njll.Okokuqala, i-magnetite ihlukaniswa yizibuthe ezibuthakathaka, bese i-ilmenite ihlukaniswa yindandatho eqondile enamandla aphakathi nendawo. Indandatho eqinile emile yensimu ephezulu yensingo emile isusa amanye amaminerali anensimbi, bese amandla adonsela phansi amancane ahlukaniswa indlela yokuhlukanisa amandla adonsela phansi. Ngesihlabathi solwandle, amaminerali asindayo yi-rutile nesihlabathi se-zircon. I-rutile ene-conductivity engcono ingakhethwa ngokuhlukaniswa kukagesi, ukuze kugcwalise ukuhlukaniswa okuphumelelayo kwalolu hlobo lwamaminerali.
Iringithoni eqondile yesihlukanisi esinegrediyenti kazibuthe
Icala lokuhlomula
Kukhona i-magnetite, i-titanomagnetite, i-ilmenite, i-rutile, isihlabathi se-zircon, isihlabathi solwandle kanye nenani elincane lamaminerali ane-iron kuma-alluvial placers e-Indonesia.,Phakathi kwazo, i-ilmenite, i-rutile, nesihlabathi se-zircon yizona amaminerali aqondiswe kakhulu, futhi i-titanomagnetite, i-iron oxide, i-iron silicate, nesihlabathi solwandle ukungcola. Amaminerali ahlukaniswa futhi afaneleke ngezindlela ezibonakalayo ezifana nokuhlukaniswa kazibuthe nokuhlukaniswa kwamandla adonsela phansi. Yonke imikhiqizo egxilile.Phakathi kwayo i-ilmenite, i-rutile, i-zircon ingamaminerali ahlosiwe ayinhloko, i-ilmenite, i-iron oxide, i-iron silicate, isihlabathi solwandle njengokungcola, Ngokuhlukana kazibuthe, ukuhlukaniswa kwamandla adonsela phansi nezinye izindlela ezibonakalayo, amaminerali ahlukaniswa futhi afanelekayo imikhiqizo yokugxila kukhethiwe.
Usayizi wezinhlayiyana zesihlabathi se-alluvial ufana, futhi usayizi wezinhlayiyana ojwayelekile ngu-0.03 ~ 0.85 mm. Imikhiqizo ye-concentrate efanelekayo efana ne-ilmenite, rutile kanye ne-zircon sand ihlukaniswa inqubo ehlanganisiwe yokuzuza kokuhlukaniswa okubuthakathaka kazibuthe + ukuhlukaniswa kazibuthe okuphakathi + ukuhlukana okuphezulu kazibuthe + ukuhlukaniswa kwamandla adonsela phansi.
- Inkomba yenzuzo ikhonjiswe kuThebula lesi-4.
Umdwebo 1. Inqubo yokuhlola i-beneficiation ehlanganisiwe ye-alluvial sand ore
Ithebula 4. Izinkomba Zokuhlolwa Kwenzuzo Ehlangene
Kusetshenziswa umehluko ekuthambekeni kokuthi kazibuthe okuqondile kanye nokuminyana phakathi kwamaminerali, ngenqubo ehlanganisiwe yokuhlukaniswa okubuthakathaka kazibuthe + okuqinile kazibuthe + amandla adonsela phansi, i-ilmenite igxila ngesivuno esingu-25.37%, ibanga le-TiO2 lama-46.39%, kanye nezinga lokululama lika-60.83% kwaba select.rutile concentrate nesivuno 8.52 %, TiO2 grade 66.15 % kanye nokululama 29.15 % ;Zircon placer concentrate with isivuno 40.15%, ZrO2 grade 58.06%, and rate recovery of 89.41% more concentrate. i-titanomagnetite, ngakho-ke imikhiqizo yensimbi efanelekile ayikwazi ukukhethwa.
