Izakhiwo zamaminerali kanye nesakhiwo samaminerali
Amaminerali aphethe i-titanium ahlanganisa kakhulu i-ilmenite, i-rutile, i-anatase, i-brookite, i-perovskite, i-sphene, i-titanomagnetite, njll., phakathi kwawo i-ilmenite ne-rutile kuyizona zimaminerali eziyinhloko zokuncibilikisa i-titanium.
Ifomula yama-molecule ye-ilmenite yi-FeTiO3, ngokwethiyori equkethe u-52.66% we-TiO2 kanye no-47.34% we-FeO. Iwuhlobo lwensimbi olumpunga olusuka ku-ore olumnyama kuya koluphuzi, olunobunzima be-Mohs obungu-5-6, ubuningi obungu-4.72g/cm3, i-magnetism ephakathi nendawo, umqhubi omuhle, kanye nohlobo olujwayelekile. Ubunikazi bekhwalithi buxutshwe ne-magnesium kanye ne-manganese, noma buqukethe ukufakwa kwe-hematite okunciphile.
Ifomula yama-molecule ye-rutile yi-TiO2, equkethe i-60% Ti kanye ne-40% O. Iyiminerali ebomvu ngokunsundu, evame ukuqukethe ingxube yensimbi, i-niobium, i-chromium, i-tantalum, i-tin, njll., enobunzima be-Mohs obungu-6, kanye nobuningi obungu-4.2 ~ 4.3g/cm3. I-Magneticism, i-conductivity enhle, onsundu omnyama lapho okuqukethwe kwensimbi kuphezulu, i-rutile ikhiqizwa kakhulu kuma-placers.
Izinkambu zohlelo lokusebenza kanye nezinkomba zobuchwepheshe
I-Rutile ne-ilmenite yizinto eziyinhloko zokusetshenziswa kokuncibilikisa i-titanium yensimbi, ukukhiqiza i-titanium dioxide, izinduku zokushisela, kanye nokushintshashintsha kokushisa.

Ithebula 2. Izinga Lekhwalithi Ye-Titanium Concentrate
Ithebula 3. Izindinganiso Zekhwalithi Zemvelo Ze-Rutile
Ubuchwepheshe bokucubungula
Ngokuvamile i-ilmenite ne-rutile ore zihambisana nezinye izimbiwa ezahlukahlukene, njenge-magnetite, i-hematite, i-quartz, i-feldspar, i-amphibole, i-olivine, i-garnet, i-chromite, i-apatite, i-mica, i-pyroxene. Amatshe, njll., ngokuvamile akhethwa ngokuhlukaniswa kwamandla adonsela phansi, ukuhlukaniswa kwamagnetic, ukuhlukaniswa kukagesi kanye nokuntanta.
Ukuzuza amandla adonsela phansi
Le ndlela ivame ukusetshenziselwa ukuhlukaniswa okuqinile kwe-placer equkethe i-titanium noma i-ore eyinhloko equkethe i-titanium echotshoziwe. Ubuningi bamaminerali aqukethe i-titanium ngokuvamile bukhulu kuno-4g/cm3. Ngakho-ke, ama-gangue amaningi anobukhulu obungaphansi kuka-3g/cm3 angasuswa ngokuhlukaniswa kwamandla adonsela phansi. Ukususwa kwamaminerali. Imishini yokuhlukanisa amandla adonsela phansi ifaka i-jig, i-spiral concentrator, i-shaker, i-chute, njll.
Ukuhlukaniswa kwamagnetic
Indlela yokuhlukanisa amandla kazibuthe isetshenziswa kabanzi ekukhetheni amaminerali aqukethe i-titanium. Singasebenzisa ukuhlukaniswa kwamandla kazibuthe okubuthakathaka ukuhlukanisa i-magnetite, bese sisebenzisa ukuhlukaniswa kwamandla kazibuthe okunamandla ukuhlukanisa i-ilmenite enamandla kazibuthe. Isibonelo, i-concentrate iqukethe i-iron oxide eyengeziwe noma i-iron silicate, indlela yokuhlukanisa amandla kazibuthe kufanele isetshenziswe ukususa ukungcola okunamandla adonsela phansi amancane. Embonini, kokubili ukuhlukaniswa kwamandla kazibuthe okomile nokumanzi kuyasetshenziswa. Imishini yokuhlukanisa amandla kazibuthe ihlanganisa ikakhulukazi i-cylindrical magnetic separator, i-plate magnetic separator, i-vertical ring high gradient magnetic separator, njll.
Isihlukanisi sikamazibuthe sedramu
Isihlukanisi semagnethi sepuleti likamagnetic esinamandla kakhulu
Ukuzuza ngogesi
Isebenzisa kakhulu umehluko ekuqhutshweni kwamandla phakathi kwamaminerali ahlukene ku-coarse concentrate equkethe i-titanium ukuze ikhethe, njengokuhlukaniswa kwe-rutile, i-zircon, ne-monazite. Izihlukanisi zikagesi ezisetshenziswayo uhlobo lwe-roller, uhlobo lwepuleti, uhlobo lwepuleti lesihlungo njalo njalo.
Ukuntanta
Isetshenziswa kakhulu ukuhlukanisa i-ore equkethe i-titanium ecolekileyo. Ama-reagent okuflotha asetshenziswa kakhulu afaka i-sulfuric acid, i-oyela ende, i-oleic acid, i-diesel oil kanye nama-emulsifier. Izindlela zokuzuza zihlanganisa ukuflotha kwe-titanium okuhle kanye nokuflotha kwe-gangue okuphambene.
Ukuzuza okuhlangene
Ku-placerite enamaminerali ahlobene kakhulu, umehluko ekuthambekeni okuthile kwamagnetic, ubuningi, ukuhanjiswa kwamandla, kanye nokuntanta phakathi kwamaminerali ungasetshenziswa ukuhlukanisa amaminerali ngenqubo ehlanganisiwe "ye-magnetic, esindayo, kagesi, kanye ne-float". Isibonelo, isihlabathi se-alluvial esisogwini siqukethe amaminerali afana ne-magnetite, i-ilmenite, i-rutile, isihlabathi se-zircon, i-monazite, isihlabathi solwandle, njll. Okokuqala, i-magnetite ihlukaniswa yinsimu yamagnetic ebuthakathaka, bese i-ilmenite ihlukaniswa yindandatho eqondile enamandla ensimu ephakathi. Indandatho eqondile enamandla ensimu ephezulu ye-vertical ring tailings isusa amanye amaminerali aphethe insimbi, bese kuthi amandla amancane adonsela phansi ahlukaniswe ngendlela yokuhlukanisa amandla adonsela phansi. Esihlabathini solwandle, amaminerali asindayo yi-rutile kanye nesihlabathi se-zircon. I-rutile enokuhanjiswa kwamandla okungcono ingakhethwa ngokuhlukaniswa kukagesi, ukuze kuqedwe ukuhlukaniswa okusebenzayo kwalolu hlobo lwamaminerali.
Isihlukanisi sikamazibuthe esiqondile se-gradient ephezulu
Icala lenzuzo
Kukhona i-magnetite, i-titanomagnetite, i-ilmenite, i-rutile, isihlabathi se-zircon, isihlabathi solwandle kanye nenani elincane lamaminerali aphethe insimbi ezindaweni zokubeka i-alluvial e-Indonesia.，Phakathi kwazo, i-ilmenite, i-rutile, kanye nesihlabathi se-zircon yizona minerali eziyinhloko eziqondiwe, kanti i-titanomagnetite, i-iron oxide, i-iron silicate, kanye nesihlabathi solwandle kungukungcola. Amaminerali ahlukaniswa futhi afaneleke ngezindlela ezibonakalayo njengokuhlukaniswa kwamagnetic kanye nokuhlukaniswa kwamandla adonsela phansi. Yonke imikhiqizo yokugxila. Phakathi kwazo i-ilmenite, i-rutile, i-zircon yizona minerali eziyinhloko eziqondiwe, i-ilmenite, i-iron oxide, i-iron silicate, isihlabathi solwandle njengokungcola, Ngokuhlukaniswa kwamagnetic, ukuhlukaniswa kwamandla adonsela phansi kanye nezinye izindlela ezibonakalayo, amaminerali ayahlukaniswa futhi kukhethwa imikhiqizo yokugxila efanelekile.
Usayizi wezinhlayiya zesihlabathi esinamanzi amaningi uyafana, kanti usayizi wezinhlayiya ojwayelekile u-0.03 ~ 0.85 mm. Imikhiqizo efanelekile yokugxila njengesihlabathi se-ilmenite, i-rutile kanye ne-zircon ihlukaniswa ngenqubo yokuzuza ehlanganisiwe yokuhlukaniswa okubuthakathaka kwamagnetic + ukuhlukaniswa okuphakathi kwamagnetic + ukuhlukaniswa okuphezulu kwamagnetic + ukuhlukaniswa kwamandla adonsela phansi.
- Inkomba yokuzuza iboniswe kuThebula 4.
Isithombe 1. Inqubo yokuhlola ukuhlomula ehlanganisiwe ye-alluvial sand ore
Ithebula 4. Izinkomba Zokuhlolwa Kokuzuza Okuhlangene
Kusetshenziswa umehluko ekuthambekeni okuthile kwamagnetic kanye nobuningi phakathi kwamaminerali, ngenqubo ehlanganisiwe yokuhlukaniswa kwe-magnetic ebuthakathaka + enamandla kamagnetic + amandla adonsela phansi, kukhethwe ama-concentrates e-ilmenite anesivuno esingu-25.37%, ibanga le-TiO2 elingu-46.39%, kanye nesilinganiso sokululama esingu-60.83%. I-rutile concentrates enesivuno esingu-8.52%, ibanga le-TiO2 elingu-66.15% kanye nokululama okungu-29.15%; I-Zircon placer concentrates enesivuno esingu-40.15%, ibanga le-ZrO2 elingu-58.06%, kanye nesilinganiso sokululama esingu-89.41%. I-Iron concentrates iqukethe i-titanomagnetite eyengeziwe, ngakho-ke imikhiqizo ye-iron concentrates efanelekile ayikwazi ukukhethwa.
