Nkowa mmalite nke Tungsten ore na itinye uche

Dị ka anyị niile maara, tungsten carbide na-mere si tungsten ore. Na n'isiokwu a, ị nwere ike ịlele ụfọdụ ozi gbasara tungsten ore na itinye uche. Isiokwu a ga-akọwa ores tungsten ma lekwasị anya n'akụkụ ndị a:

1. Nkowa nkenke nke tungsten ore na itinye uche;

2. Ụdị dị iche iche nke tungsten ore na itinye uche

1. Nkowa mmalite nke tungsten ore na itinye uche

Ọnụ ọgụgụ tungsten dị n'ime ụwa dị ntakịrị. Ka ọ dị ugbu a, a chọtara ụdị mineral 20 nke tungsten, n'ime ha naanị wolframite na scheelite nwere ike ịgbaze. 80% nke tungsten ore zuru ụwa ọnụ dị na China, Russia, Canada na Vietnam. China nwere 82% nke tungsten zuru ụwa ọnụ.

China tungsten ore nwere obere ọkwa na mgbagwoju mejupụtara. 68.7% n'ime ha bụ scheelite, onye ego ya dị ala na àgwà ya dị ala. 20.9% n'ime ha bụ wolframite, onye ogo ya dị elu. 10.4% bụ ore agwakọta, gụnyere scheelite, wolframite, na mineral ndị ọzọ. O siri ike ịpụ. Mgbe ihe karịrị otu narị na-egwuputa ihe na-aga n'ihu, agwụla wolframite dị elu, na àgwà scheelite dị ala. N'ime afọ ndị na-adịbeghị anya, ọnụahịa tungsten ore na itinye uche na-arị elu.

2. Ụdị dị iche iche nke tungsten ore na itinye uche

Enwere ike ime Wolframite na scheelite itinye uche site na nchipịa, igwe igwe bọọlụ, ike ndọda, nkewa eletrik, nkewa magnetik, na usoro ndị ọzọ. Akụkụ bụ isi nke tungsten concentrate bụ tungsten trioxide.

Wolframite itinye uche

Wolframite, makwaara dị ka (Fe, Mn) WO4, bụ aja aja-oji, ma ọ bụ oji. Wolframite itinye uche na-egosi ncha nke ọkara ọla ma bụrụ nke sistemụ monoclinic. A na-enwekarị kristal nke nwere ogologo eriri na ya. Wolframite na-abụkarị symbiotic nwere veins quartz. Dị ka ụkpụrụ ntinye uche tungsten nke China si kwuo, a na-ekewa ndị wolframite n'ime wolframite special-I-2, wolframite special-I-1, wolframite grade I, wolframite grade II, na wolframite grade III.

Scheelite itinye uche

Scheelite, nke a makwaara dị ka CaWO4, nwere ihe dịka 80% WO3, na-abụkarị isi awọ na-acha ọcha, mgbe ụfọdụ ọ na-acha odo odo, na-acha odo odo, na agba ndị ọzọ, na-egosi diamond luster ma ọ bụ griiz luster. Ọ bụ sistemụ kristal tetragonal. Ụdị kristal na-abụkarị biconical, na mkpokọta na-abụkarị granular ma ọ bụ nnukwu ngọngọ. Scheelite na-abụkarị symbiotic na molybdenite, galena, na sphalerite. Dị ka ọkọlọtọ tungsten nke obodo m si dị, scheelite concentrate na-ekewa n'ime scheelite-II-2 na scheelite-II-1.

3. Ngwa nke tungsten concentrate

Tungsten concentrate bụ isi akụrụngwa maka mmepụta nke tungsten ngwaahịa niile na-esote ụlọ ọrụ yinye, na ya kpọmkwem ngwaahịa bụ isi akụrụngwa maka tungsten ogige dị ka ferrotungsten, sodium tungstate, ammonium para tungstate (APT), na ammonium metatungstate. AMT). Tungsten concentrate nwere ike iji rụpụta tungsten trioxide (blue oxide, odo oxide, purple oxide), ndị ọzọ na etiti ngwaahịa, na ọbụna pigmenti na ọgwụ mgbakwunye, na kasị mara mma bụ evolushọn na-aga n'ihu na mgbalị nke precursors dị ka violet tungsten na ubi nke ọhụrụ ume batrị.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe.
