Umlando wokuthuthukiswa kwe-tantalum metal

Nakuba i-tantalum yatholwa ekuqaleni kwekhulu le-19, i-metal tantalum yayingekho

kwaze kwaba ngu-1903, futhi ukukhiqizwa kwezimboni ze-tantalum kwaqala ngo-1922.

ukuthuthukiswa kwemboni ye-tantalum emhlabeni kwaqala ngawo-1920, kanye neChina

imboni ye-tantalum yaqala ngo-1956.

I-United States iyizwe lokuqala emhlabeni ukuqala ukukhiqiza i-tantalum. Ngo-1922,

yaqala ukukhiqiza i-metal tantalum ngezinga lezimboni. Japan kanye nezinye capitalist

amazwe wonke aqala ukuthuthukisa imboni ye-tantalum ngasekupheleni kwawo-1950 noma ekuqaleni kwawo-1960.

Ngemva kwamashumi eminyaka yentuthuko, ukukhiqizwa tantalum imboni emhlabeni has

ifinyelele ezingeni eliphezulu kakhulu. Kusukela ngawo-1990, abakhiqizi abakhulu be-

imikhiqizo ye-tantalum ihlanganisa i-American Cabot Group (i-American Cabot, i-Japanese Showa

I-Cabot), i-German HCST Group (i-HCST yaseJalimane, i-NRC yaseMelika, i-V-Tech yaseJapane, kanye

I-Thai TTA) kanye ne-Chinese Ningxia Dongfang Tantalum Co., Ltd. Amaqembu amathathu amakhulu

ye-China Industrial Co., Ltd., ukukhiqizwa kwemikhiqizo ye-tantalum yilaba abathathu

amaqembu abala ngaphezu kuka-80% wengqikithi yomhlaba. Imikhiqizo, ubuchwepheshe kanye

imishini yemboni ye-tantalum yangaphandle ngokuvamile iphakeme kakhulu, ihlangabezana nezidingo

yentuthuko esheshayo yesayensi nobuchwepheshe emhlabeni.

Imboni ye-tantalum yaseChina yaqala ngawo-1960. Uma kuqhathaniswa namazwe athuthukile,

I-tantalum yokuqala yaseChina yokuncibilikisa, ukucutshungulwa kanye nesikali sokukhiqiza, izinga lobuchwepheshe,

izinga lomkhiqizo kanye nekhwalithi kusemuva kakhulu. Kusukela ngawo-1990, ikakhulukazi kusukela ngo-1995,

Ukukhiqizwa kwe-tantalum yaseShayina nokusebenzisana kubonise umkhuba wokuthuthuka okusheshayo.

Namuhla, imboni ye-tantalum yaseChina iye yabona uguquko ukusuka “kokuncane kuye kokukhulu,

kusukela kwezempi kuya kwabavamile, futhi kusukela ngaphakathi kuye ngaphandle”, ukwakha okuwukuphela kweThe

uhlelo lwezimboni kusukela ezimayini, ukuncibilikisa, ukucutshungulwa kuya ekusetshenzisweni, okuphezulu, okuphakathi kanye

imikhiqizo esezingeni eliphansi ingene emakethe yamazwe ngamazwe ngendlela eyindilinga. I-China ikwenzile

ibe yizwe lesithathu ngobukhulu emhlabeni ekuncibilikiseni nasekucutshungulweni kwe-tantalum, futhi

ingene ezinhlwini zamazwe emboni ye-tantalum amakhulu kunawo wonke emhlabeni.
