Uburyo bwa Agglomeration Uburyo bwo gufungura umunwa wumuriro w'amashanyarazi ushobora kwimurwa kuri gari ya moshi naho igice cyo hejuru cyumubiri w itanura gishobora gukoreshwa, naho karubone ikoreshwa nkibikoresho bigabanya. Amabuye meza ya tungsten, kokiya ya asifalt (cyangwa peteroli ya kokiya) hamwe na agent ya slagging (bauxite) igizwe nuruvange rwamafaranga yongewe mumatara mugice kimwekindi, icyuma gitunganijwe mumatanura muri rusange kiragaragara, hamwe nubunini bwikirenga, igice cyo hasi cyo gukomera buhoro buhoro. Kwiyegeranya kw'itanura nyuma yo guhagarika itanura, gukuramo umubiri w'itanura, kura igice cyo hejuru cyumubiri witanura kugirango ibibyimba byegeranye. Noneho fata agglomerates yo kumenagura no kurangiza; hitamo impande, hamwe na slag hamwe nibice bitujuje ibyangombwa usubire mu ziko kugirango usubiremo. Ibicuruzwa birimo tungsten hafi 80% kandi ntibirenze 1% ya karubone.
Uburyo bwo gukuramo ibyuma burakwiriye gushonga ferro-tungsten irimo 70% tungsten hamwe no gushonga hasi. Silicon na karubone bikoreshwa nka reductants; ikorwa mubyiciro bitatu: kugabanya (nanone bita slag depletion), gutunganya no gukuramo ibyuma. Itanura ryicyiciro kirimo itanura ryo gufata icyuma gisigaye nyuma yicyapa kirimo WO3 kirenze 10%, hanyuma kigahita kongerwaho amafaranga ya tungsten, hanyuma kongerwaho kuri silicon 75% ferrosilicon hamwe na kokiya ya asifalt (cyangwa peteroli ya kokiya) kugirango igabanye gushonga, kuba slag irimo WO3 kumanuka kugeza 0.3% munsi yigituba. Nyuma yimuriwe murwego rwo gutunganya, muriki gihe, wongeyeho tungsten concentrate, ivangwa rya kokiya ya asfalt mubice, ikoreshwa na voltage nyinshi, mubushyuhe bwo hejuru kugirango ikureho silikoni, manganese nibindi byanduye. Ikizamini cyicyitegererezo kugirango umenye ibice byujuje ibyangombwa, byatangiye gufata ibyuma. Mugihe cyo gukuramo ibyuma, intungamubiri za tungsten hamwe na kokiya ya asfalt iracyongerwaho uko bikwiye ukurikije itanura. Gukoresha ingufu zikoresha hafi 3.000 kW-hr / toni, igipimo cya tungsten cyo kugarura hafi 99%.
Uburyo bwa aluminium yubushyuhe kugirango ukoreshe imyanda ya tungsten karbide yifu ya tungsten hamwe na cobalt itandukanya cobalt ikuramo karubide ya tungsten yongeye kuvuka, yashyizeho uburyo bwa aluminium yumuriro wa ferro-tungsten, hamwe na karubide ya tungsten hamwe nicyuma nkibikoresho fatizo, aluminium nkibisubirwamo, gukoresha karbide ya tungsten muri karubone yayo na aluminiyumu yaka umuriro, kugirango ibikoresho bibisi muri tungsten na fer muri ferro-tungsten, bishobora kuzigama amashanyarazi menshi, no kugabanya ibiciro. Muri icyo gihe, kubera ko umwanda uri mu bikoresho fatizo bya karubide ya tungsten uri munsi cyane ugereranije n’ibiri muri tungsten, ubwiza bwibicuruzwa buri hejuru ya ferrotungsten ukoresheje tungsten yibikoresho nkibikoresho fatizo. Igipimo cyo gukira kwa tungsten nacyo kiri hejuru yicyakozwe hakoreshejwe tungsten yibanze nkibikoresho fatizo.
