Kev faib khoom ntawm cov khoom siv titanium hauv Suav teb
Titanium reserves nyob rau hauv lub ntiaj teb yog nplua nuj heev. Hauv kaum-kilometer-thick strata ntawm lub ntiaj teb saum npoo av, titanium yog 6/1000, 61 npaug ntau dua tooj liab, thiab nyob rau qib kaum hauv lub ntiaj teb crust (cov ntsiab lus hauv lub ntiaj teb crust: oxygen, silicon, txhuas, hlau, calcium, sodium. , potassium, magnesium, hydrogen, titanium). Tsuas yog lob ib txhais tes ntawm av los ntawm av, thiab nws muaj ob peb txhiab ntawm titanium. Titanium ore nrog reserves ntawm ntau tshaj 10 lab tons nyob rau hauv lub ntiaj teb no yog tsis tshua muaj.
1. Kev faib khoom ntawm titanium hauv Suav teb
Tuam Tshoj cov khoom siv titanium tag nrho yog 965 lab tons, nyob rau hauv thawj lub ntiaj teb, suav txog 38.85% ntawm lub ntiaj teb cov pov thawj pov thawj, feem ntau yog concentrated hauv Sichuan, Yunnan, Guangdong, Guangxi thiab Hainan. Ntawm lawv, Panxi (Panzhihua Xichang) yog Tuam Tshoj tus loj tshaj plaws titanium peev txheej, nrog titanium peev txheej ntawm 870 lab tons. Tuam Tshoj cov ntaub ntawv pov thawj titanium tau muab faib rau hauv 108 qhov chaw mining hauv 21 lub xeev (cov cheeb tsam tswj hwm, cov nroog). Qhov chaw tsim khoom tseem ceeb yog Sichuan, ua raws li Hebei, Hainan, Guangdong, Hubei, Guangxi, Yunnan, Shaanxi, Shanxi thiab lwm lub xeev ( cheeb tsam).
2. Titanium smelting
Titanium yog cov hlau tsis tshua muaj. Qhov tseeb, titanium tsis yog tsawg. Nws qhov kev nplua nuj nyob hauv lub ntiaj teb pob zeb yog qib xya, suav nrog 0.45%, uas yog ntau dua li ntau hom hlau. Txawm li cas los xij, vim muaj qhov ua haujlwm ntawm titanium thiab cov kev xav tau siab rau kev siv tshuab smelting, tib neeg tsis tuaj yeem tsim cov titanium ntau rau lub sijhawm ntev, yog li nws tau muab cais ua "tsis tshua muaj" hlau. Cov zaub mov uas siv los smelt titanium feem ntau yog ilmenite (FeTiO3) thiab rutile (TiO2). Cov ore raug kho kom tau cov titanium tetrachloride tsis muaj zog, uas tom qab ntawd txo nrog magnesium kom tau txais cov ntshiab titanium.
3. Titanium ore
Lub ntsiab ores ntawm titanium yog rutile TiO2 thiab ilmenite FeTiO3, thiab nws qhov kev tshawb pom los ntawm kev txheeb xyuas ntawm ob lub ores. Thaum ntxov li 1791, Gregor, ib tug xibhwb ntawm Menacan Parish hauv Cornwall, sab hnub poob teb chaws Askiv, kuj yog ib tug kws tshawb fawb. Thaum txheeb xyuas cov ore dub uas tsim nyob rau hauv nws pawg ntseeg, uas yog cov ore ntawm ilmenite niaj hnub no, nws nrhiav tau ib yam khoom hlau tshiab thiab hu ua menacenite. Peb xyoos tom qab ntawd, xyoo 1795, Klaproth tau tshuaj xyuas cov rutile uas tsim nyob rau hauv cheeb tsam Boinik ntawm Hungary thiab pom tau hais tias nws yog ib qho oxide ntawm cov hlau tshiab uas muaj cov yam ntxwv ntawm kev tiv thaiv cov kua qaub thiab alkaline. Nws hu ua cov hlau titanium tom qab Titans, thawj cov tub ntawm lub ntiaj teb nyob rau hauv Greek mythology, thiab lub cim cim tau teem ua Ti. Ob xyoos tom qab, Klaproth tau lees paub tias cov menacenite pom los ntawm Gregor yog titanium.

Lub ntsiab deposits yog faib nyob rau hauv Yanbian Hongge thiab Miyi Baima nyob rau hauv Panzhihua, Sichuan Province, Taihe nyob rau hauv Xichang; Damiao thiab Heishan hauv Chengde, Hebei Xeev, Zhaobinggou hauv Fengning, Nantianmen hauv Chongli; Tongyu hauv Zuoquan, xeev Shanxi; Bijigou hauv Yangxian, Shaanxi Province; Weiya hauv Xinjiang; Zhaoanzhuang hauv Wuyang, Henan Province; Xialan hauv Xingning, Guangdong xeev; Huma hauv xeev Heilongjiang; Shangzhuang hauv Changping, Beijing thiab Xindi hauv Huairou. Ntawm lawv, Sichuan Xeev cov nyiaj tshuav nyiaj tshuav (TiO2 442.5632 lab tons) suav txog 95.1% ntawm lub tebchaws zoo sib xws (TiO2 465.2283 lab tons), Hebei Xeev (TiO{{ 7}}.4446 lab tons) suav txog 3.3%, Shaanxi Xeev suav rau 0.46%, thiab Shanxi Xeev suav rau 0.35%.
2>Rutile pob zeb ore
Lub ntsiab deposits yog faib nyob rau hauv Dafushan, Zaoyang, Hubei xeev; Nianzigou, Dai County, Shanxi xeev; Yangchong, Xin County, Henan xeev; Liujiazhuang, Laixi County, Shandong xeev. Ntawm lawv, Hubei Xeev cov ntawv tshuav nyiaj tshuav ntawm rutile (TiO2) (5.3443 lab tons) suav txog 71.2% ntawm lub tebchaws zoo sib xws (7.5086 lab tons), Shanxi Province (1.5479 lab tons) suav txog 20.6%, thiab Shaanxi Province. (444,{13}} tons) suav txog 5.9%.
Tuam Tshoj cov khoom siv titanium tsis yog tsuas yog muaj nyob rau hauv reserves xwb, tab sis kuj theem ntawm kev loj hlob thiab kev siv yog tas li txhim kho. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho kev lag luam, Tuam Tshoj txoj kev lag luam titanium tau maj mam tsim cov saw hlau ua tiav los ntawm titanium ore mining mus rau titanium dioxide, sponge titanium, titanium cov ntaub ntawv thiab lwm yam khoom siv sib sib zog nqus. Tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ntawm titanium dioxide thiab daim txhuam cev titanium, Tuam Tshoj tus ntau lawm thiab export ntim yog cov siab tshaj plaws nyob rau hauv lub ntiaj teb no, ua ib tug tseem ceeb pab rau txoj kev loj hlob ntawm lub ntiaj teb no titanium kev lag luam.
