Ngā āhuatanga kohuke me te hanganga kohuke
Ko ngā kohuke whai titanium ko te ilmenite, te rutile, te anatase, te brookite, te perovskite, te sphene, te titanomagnetite, me ētahi atu, ā, ko te ilmenite me te rutile ngā kohuke whakarewa titanium matua.
Ko te tātai ngota o te ilmenite ko FeTiO3, kei roto i te ariā he 52.66% o TiO2 me te 47.34% o FeO. He konganuku maitai hina ki te pango, he pakeke Mohs o te 5-6, he mātotoru o te 4.72g/cm3, he aukume waenga, he pai te kawe hiko, ā, he momo noa. Ko te āhua ōrite ka konatunatua ki te konupūmā me te manganese, kei roto rānei he whakauru hematite unahi pai.
Ko te tātai ngota o te rutile ko TiO2, kei roto ko te 60% Ti me te 40% O. He kohuke parauri-whero, he maha ngā wā kei roto he ranunga o te rino, te niobium, te chromium, te tantalum, te tine, me ētahi atu, ko te pakeke Mohs he 6, me te mātotoru o te 4.2~4.3g/cm3. He aukume, he pai te kawe hiko, he parauri pouri ina nui te ihirangi rino, ko te nuinga o te wā ka puta te rutile i roto i ngā placer.
Ngā mara tono me ngā tohu hangarau
Ko te rutile me te ilmenite ngā rauemi mata matua mō te whakarewa i te titanium whakarewa, te hanga titanium dioxide, ngā rakau whakarewa, me ngā rerenga whakarewa.

Ripanga 3. Ngā Paerewa Kounga o te Rutile Taiao
Hangarau tukatuka
I te nuinga o te wā, ka haere tahi te ilmenite me te rutile me te maha atu o ngā kohuke, pērā i te magnetite, te hematite, te quartz, te feldspar, te amphibole, te olivine, te garnet, te chromite, te apatite, te mika, te pyroxene. Ko ngā kōhatu, me ētahi atu, ka tīpakohia mā te wehenga ā-papa, te wehenga aukume, te wehenga hiko me te whakamānu.
Te painga o te kaha ā-papatipu
Ko tēnei tikanga e whakamahia whānuitia ana mō te wehenga matapōkere o te mea whakatakoto kei roto te titanium, te konganuku tuatahi rānei kei roto te titanium kuruhia. Ko te mātotoru o ngā kohuke kei roto te titanium he nui ake i te 4g/cm3. Nō reira, ko te nuinga o ngā gangue he iti iho i te 3g/cm3 te mātotoru ka taea te tango mā te wehenga ā-papa. Te tango kohuke. Kei roto i ngā taputapu wehenga ā-papa te jig, te concentrator porowhita, te ru, te chute, me ētahi atu.
Wehenga aukume
He whānuitia te whakamahinga o te tikanga wehenga aukume i roto i te whiriwhiri i ngā kohuke kei roto te titanium. Ka taea e tātou te whakamahi i te wehenga aukume ngoikore hei wehe i te aukumeiti, kātahi ka whakamahi i te wehenga aukume kaha hei wehe i te ilmenite aukume reo-waenga. Hei tauira, he nui ake te waikura rino kei roto i te kukū, i te silicate rino rānei, me whakamahi te tikanga wehenga taumaha hei tango i ngā poke me te taumaha motuhake iti. I roto i te ahumahi, ka whakamahia te wehenga aukume maroke me te mākū. Ko ngā taputapu wehenga aukume ko te wehenga aukume porotaka, te wehenga aukume pereti, te wehenga aukume porowhita teitei poutū, me ētahi atu.

Te whakapai ake i te hikohiko
Ko te nuinga o te wā, ka whakamahia te rerekētanga o te kawe hiko i waenga i ngā kohuke rerekē i roto i te kukū matotoru kei roto te titanium hei whiriwhiri, pērā i te wehenga o te rutile, te zircon, me te monazite. Ko ngā wehewehe hiko e whakamahia ana ko te momo roera, te momo pereti, te momo pereti tātari me ētahi atu.
Te Whakaterenga
Ko te nuinga o te wā ka whakamahia hei wehewehe i ngā konganuku kei roto he titanium pai. Ko ngā matū whakapūmau e whakamahia whānuitia ana ko te waikawa whanariki, te hinu teitei, te waikawa oleic, te hinu tīhiera me ngā emulsifier. Ko ngā tikanga whakapai ake ko te whakapūmau pai o te titanium me te whakapūmau whakamuri o ngā kohuke gangue.
Te whakawhiwhinga painga tahi
Mō te placerite me ngā kohuke e pā ana, ka taea te whakamahi i te rerekētanga o te ngoikore o te aukume motuhake, te mātotoru, te kawe hiko, me te mānu i waenga i ngā kohuke hei wehe i ngā kohuke mā te tukanga whakakotahi o te "aukume, taumaha, hiko, me te mānu". Hei tauira, kei roto i te onepu awaawa takutai ngā kohuke pēnei i te magnetite, te ilmenite, te rutile, te onepu zircon, te monazite, te onepu moana, me ētahi atu. Tuatahi, ka wehea te magnetite e te papa aukume ngoikore, kātahi ka wehea te ilmenite e te mowhiti poutū me te kaha papa waenga. Ka tangohia e te mowhiti poutū kaha papa teitei o ngā toenga mowhiti poutū ētahi atu kohuke e mau ana i te rino, kātahi ka wehea te taumaha motuhake iti e te tikanga wehenga taumaha. Mō te onepu moana, ko ngā kohuke taumaha ko te rutile me te onepu zircon. Ka taea te whiriwhiri i te rutile he pai ake te kawe hiko mā te wehenga hiko, kia oti ai te wehenga whai hua o tēnei momo kohuke.

Kehi painga
Kei roto i ngā papa whenua alluvial o Indonesia te magnetite, te titanomagnetite, te ilmenite, te rutile, te onepū zircon, te onepū moana me te iti noa o ngā kohuke whai rino.，I roto i ēnei, ko te ilmenite, te rutile, me te onepu zircon ngā kohuke matua e whaia ana, ā, ko te titanomagnetite, te waikura rino, te silicate rino, me te onepu moana he paru. Ka wehea, ka tohua hoki ngā kohuke mā ngā tikanga ā-tinana pēnei i te wehenga aukume me te wehenga ā-papa. Ngā hua kukū katoa. I roto i ēnei ko te ilmenite, te rutile, te zircon ngā kohuke matua e whaia ana, te ilmenite, te waikura rino, te silicate rino, te onepu moana hei paru. Mā te wehenga aukume, te wehenga ā-papa me ētahi atu tikanga ā-tinana, ka wehea ngā kohuke, ā, ka tīpakohia ngā hua kukū kua tohua.
He ōrite te rahi o te matūriki o te onepu awaawa, ā, ko te rahi whānui o te matūriki he 0.03 ~ 0.85 mm. Ko ngā hua kukū whai tohu pērā i te ilmenite, te rutile me te onepu zircon ka wehea mā te tukanga painga whakakotahi o te wehenga aukume ngoikore + wehenga aukume reo + wehenga aukume teitei + wehenga kaha.
- Kei te Ripanga 4 te tātaitai painga.
Pikitia 1. Te tukanga whakamātautau painga whakakotahi o te onepū parakore
Ripanga 4. Ngā Tāurangi o te Whakamātautau Painga Ngātahi
Mā te whakamahi i te rerekētanga o te ngoikore o te aukume me te mātotoru i waenga i ngā kohuke, mā te tukanga whakakotahi o te wehenga aukume ngoikore + aukume kaha + taumaha, i tīpakohia ngā kukū ilmenite me te hua o te 25.37%, te taumata TiO2 o te 46.39%, me te tere whakaora o te 60.83%. kukū rutile me te hua o te 8.52%, te taumata TiO2 o te 66.15% me te whakaora o te 29.15%; kukū Zircon placer me te hua o te 40.15%, te taumata ZrO2 o te 58.06%, me te tere whakaora o te 89.41%. He nui ake te titanomagnetite i roto i te kukū rino, nō reira kāore e taea te tīpako i ngā hua kukū rino whai tohu.
