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 ye-molecular ye-ilmenite ithi FeTiO3, ngokomqondo 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. Imaminerali 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 nezinkomba zobuchwepheshe
I-Rutile ne-ilmenite yizinto ezingavuthiwe eziphambili zokuncibilikisa i-metallic titanium, ukukhiqiza i-titanium dioxide, izinduku zokushisela, kanye nokushintshashintsha kokushisela.
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 insimbi eyisisekelo echotshoziwe equkethe i-titanium.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-iron silicate, indlela yokuhlukanisa amandla adonsela phansi kufanele isetshenziselwe ukususa ukungcola nge-gravity encane ethize.Embonini, kusetshenziswa kokubili ukuhlukaniswa kozibuthe okomile nokumanzi.Imishini yokuhlukanisa uMagnetic ikakhulukazi ihlanganisa isihlukanisi esiyisilinda kazibuthe, isihlukanisi sikazibuthe sepuleti, iringi eqondile yesihlukanisi esine-gradient ephezulu, njll.
Isihlukanisi kazibuthe sesigubhu
Isihlukanisi esinozibuthe esinamandla amakhulu
Ukuhlomula kwe-Electrostatic
Ikakhulu isebenzisa umehluko ekuqhubeni phakathi kwamaminerali ahlukene ekugxilweni okumaholoholo kwe-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 equkethe i-titanium ecolekile.Ama-reagents e-flotation asetshenziswa kakhulu 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-flotation yamaminerali e-ganggue.
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, isihlabathi se-zircon, 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 yokugxila.Phakathi kwayo i-ilmenite, i-rutile, i-zircon ingamaminerali ayinhloko, i-ilmenite, i-iron oxide, i-iron silicate, isihlabathi solwandle njengokungcola, Ngokuhlukana kazibuthe, ukuhlukaniswa kwamandla adonsela phansi kanye 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 efanelekile yokugxila efana ne-ilmenite, i-rutile ne-zircon sand ihlukaniswa inqubo ehlanganisiwe yokuhlomula kokuhlukaniswa okubuthakathaka kazibuthe + ukuhlukaniswa kukazibuthe okuphakathi + ukuhlukaniswa 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 okuqondile kazibuthe kanye nokuminyana phakathi kwamaminerali, ngenqubo ehlanganisiwe yokuhlukaniswa okubuthakathaka kazibuthe + okuqinile kazibuthe + amandla adonsela phansi, i-ilmenite igxila ngesivuno esingu-25.37%, i-TiO2 ibanga lama-46.39%, kanye nezinga lokululama lika-60.83% kwaba select.rutile concentrate nesivuno 8.52 %, TiO2 grade 66.15 % kanye recovery 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.
