Chidule Chachidule cha Tungsten Ore ndi Concentrate

Monga tonse tikudziwa, tungsten carbides amapangidwa kuchokera ku tungsten ore. Ndipo m'nkhaniyi, mutha kuyang'ana zambiri za tungsten ore ndikuyika mtima. Nkhaniyi ifotokoza za miyala ya tungsten ndikuyang'ana kwambiri izi:

1. Chidule chachidule cha tungsten ore ndi kuganizira;

2. Mitundu yosiyana ya tungsten ore ndi kuganizira

3. Kugwiritsa ntchito tungsten ore ndi kuganizira

1. Chidule Chachidule cha tungsten ore ndi kuganizira

Kuchuluka kwa tungsten pansi pa nthaka ndi kochepa kwambiri. Pofika pano pali mitundu 20 ya mchere wa tungsten yomwe idapezeka, yomwe ndi wolframite ndi scheelite zokha zomwe zimasungunuka. 80% ya miyala yapadziko lonse ya tungsten ili ku China, Russia, Canada, ndi Vietnam. China ili ndi 82% ya tungsten padziko lonse lapansi.

China tungsten ore ili ndi kalasi yotsika komanso zovuta. 68.7% ya iwo ndi scheelite, omwe ndalama zawo zinali zochepa komanso zomwe khalidwe lawo linali lochepa. 20.9% ya iwo ndi wolframite, omwe kuchuluka kwawo kunali kokwera kwambiri. 10.4% ndi ore osakanikirana, kuphatikiza scheelite, wolframite, ndi mchere wina. Ndizovuta kuchoka. Pambuyo pa migodi yopitilira zana limodzi, wolframite wapamwamba kwambiri watopa, ndipo mtundu wa scheelite udatsika. M'zaka zaposachedwa, mtengo wa tungsten ore ndi kuganizira ukuwonjezeka.

2. Mitundu yosiyana ya tungsten ore ndi kuganizira

Wolframite ndi scheelite zitha kupangidwa mokhazikika ndikuphwanya, mphero ya mpira, kulekanitsa mphamvu yokoka, kulekanitsa magetsi, kupatukana kwa maginito, ndi njira zina. Chigawo chachikulu cha tungsten concentrate ndi tungsten trioxide.

Kukhazikika kwa Wolframite

Wolframite, yemwe amadziwikanso kuti (Fe, Mn) WO4, ndi wakuda-wakuda, kapena wakuda. Kukhazikika kwa Wolframite kumawonetsa kuwala kwa semi-metallic ndipo ndi gawo la monoclinic system. Crystal nthawi zambiri imakhala yokhuthala ndi mizere yotalikirapo pamenepo. Wolframite nthawi zambiri imagwirizana ndi mitsempha ya quartz. Malinga ndi miyezo yaku China ya tungsten, ma wolframite amagawika kukhala wolframite special-I-2, wolframite special-I-1, wolframite grade I, wolframite grade II, ndi wolframite giredi III.

Scheelite concentrate

Scheelite, yomwe imadziwikanso kuti CaWO4, ili ndi pafupifupi 80% WO3, nthawi zambiri imvi-yoyera, nthawi zina yachikasu pang'ono, yofiirira, yofiirira, ndi mitundu ina, kusonyeza kuwala kwa diamondi kapena mafuta. Ndi tetragonal Crystal system. Mawonekedwe a kristalo nthawi zambiri amakhala ngati ma biconical, ndipo zophatikizira zake nthawi zambiri zimakhala zosakhazikika kapena zomata. Scheelite nthawi zambiri imagwirizana ndi molybdenite, galena, ndi sphalerite. Malingana ndi dziko langa la tungsten concentrate standard, scheelite concentrate imagawidwa kukhala scheelite-II-2 ndi scheelite-II-1.

3. Kugwiritsa ntchito tungsten concentrate

Tungsten concentrate ndiye chinthu chofunikira kwambiri popanga zinthu zonse za tungsten pamakina opangira mafakitale, ndipo zopangira zake mwachindunji ndizomwe zimapangira mankhwala a tungsten monga ferrotungsten, sodium tungstate, ammonium para tungstate (APT), ndi ammonium metatungstate ( AMT). Tungsten concentrate ingagwiritsidwe ntchito popanga tungsten trioxide (blue oxide, yellow oxide, purple oxide), zinthu zina zapakatikati, ngakhale inki ndi zowonjezera zamankhwala, ndipo chochititsa chidwi kwambiri ndikusintha kosalekeza komanso kuyesa kwazinthu zoyambira monga violet tungsten mu gawo la mabatire atsopano amphamvu.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
