Ua unuhi ʻia ka Ilmenite mai ka ilmenite concentrate a i ʻole titanium magnetite, me nā ʻāpana nui ʻo TiO2 a me Fe. ʻO Ilmenite ka mineral titanium i hoʻohana ʻia ma ke ʻano he mau mea nui e hana i nā pigments titanium dioxide (TiO2). ʻO Titanium dioxide ka pigment keʻokeʻo koʻikoʻi loa ma ka honua, nona ka helu ma kahi o 90% o ka hoʻohana ʻana i nā mea titanium ma Kina a me ka honua.
Ua haʻaheo kā mākou hui e hāʻawi aku i kahi ākea o ka Ilmenite kiʻekiʻe e hoʻokō i nā koi e ulu nei o nā ʻoihana like ʻole. Ua unuhi ʻia ka Ilmenite mai ka ilmenite concentrate a i ʻole titanomagnetite a he mineral ia e loaʻa ana ka titanium dioxide (TiO2) a me ka hao (Fe). ʻO ia ka mea nui i hoʻohana ʻia i ka hana ʻana o ka titanium dioxide, kahi pigment keʻokeʻo kiʻekiʻe i ʻike nui ʻia me nā ʻano hoʻohana like ʻole.
Ma muli o kona keʻokeʻo kūikawā, ka opacity a me ka ʻālohilohi, hoʻohana nui ʻia ka titanium dioxide i ka hana ʻana i nā pena, nā uhi, nā plastics a me nā huahana pepa. Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka wā ʻino, ka radiation UV a me nā kemika. Eia kekahi, hoʻonui ka titanium dioxide i ke kūpaʻa a me ke ola o nā huahana like ʻole, e lilo ia i mea pono loa i nā ʻoihana he nui.
Ua hoʻokumu kā mākou hui i kahi pilina hana lōʻihi me nā mines ma ka home a ma waho e hōʻoia i ka hoʻolako mau a hilinaʻi hoʻi o ka ilmenite kiʻekiʻe. Ma o kā mākou pilina ikaika me kēia mau mines, hiki iā mākou ke hoʻolako i kā mākou mea kūʻai aku me ka ilmenite no Sulfate a i ʻole Chloride me ke kūpaʻa lōʻihi a me ke ʻano kiʻekiʻe.
ʻAno Sulfate Ilmenite:
P47, P46, V50, A51
Nā Hiʻohiʻona:
ʻO nā ʻike TiO2 kiʻekiʻe me ka solubility waikawa kiʻekiʻe, nā ʻike haʻahaʻa o P a me S.
ʻAno Chloride Ilmenite:
W57, M58
Nā Hiʻohiʻona:
Kiʻekiʻe ka nui o TiO2, kiʻekiʻe ka nui o Fe, haʻahaʻa ka nui o Ca a me Mg.
He mea hauʻoli mākou e hana pū me nā mea kūʻai aku ma ka home a ma luna o ka moku.
