Agglomeration nzira Iyo yakavhurika muromo wevira yemagetsi iyo inogona kufambiswa pane njanji uye chikamu chepamusoro chemuviri wechoto chinogona kuvharwa chinoshandiswa, uye kabhoni inoshandiswa seyo inoderedza. Fine tungsten ore, asphalt coke (kana petroleum coke) uye slagging agent (bauxite) inoumbwa nemusanganiswa wechaji inowedzerwa muchoto mumabhechi imwe mushure meimwe, simbi inonatswa muchoto inowanzoita viscous, nehupamhi hwepamusoro, chikamu chezasi chekusimbisa zvishoma nezvishoma. Furnace accumulation mushure mekumisa choto, dhonza mutumbi wechoto kunze, bvisa chikamu chepamusoro chemuviri wechoto kuitira kuti bundu riwedzere. Wobva watora ma agglomerates ekupwanya nekupedzisa; sarudza mipendero, ne slag uye zvikamu zvisina kukodzera kudzokera kuchoto chekugadzirisa zvakare. Chigadzirwa chacho chine 80% tungsten uye isingasviki 1% kabhoni.
Simbi yekubvisa nzira inokodzera kunyungudutsa ferro-tungsten ine 70% tungsten ine yakaderera kunyungudika. Silicon uye kabhoni zvinoshandiswa sezvinoderedza; inoshandiswa mumatanho matatu: kuderedza (inonziwo slag depletion), kunatsa uye kubvisa simbi. Yekudzikisa nhanho choto ine choto chekutora simbi yakasara kumashure mushure meiyo slag ine WO3 yakakura kupfuura 10%, uyezve zvakatevedzana yakawedzera kune tungsten concentrate charge, ndokuzowedzera kune silicon 75% ferrosilicon uye shoma shoma yeasphalt coke (kana petroleum coke) yekudzikisa kunyungudika, kuve slag ine WO3 pasi kusvika 0.3% pazasi pe slag. Yakazoendeswa kune yekunatsa nhanho, munguva ino, kuwedzera tungsten concentrate, asphalt coke musanganiswa mumabhechi, inoshandiswa nemhepo yakakwira, pane tembiricha yepamusoro kubvisa silicon, manganese uye kumwe kusvibiswa. Sample test yekuona kuumbwa kwevanokwanisa, vakatanga kutora simbi. Munguva yekuchera simbi, tungsten concentrate uye asphalt coke ichiri kuwedzerwa zvakakodzera maererano nemamiriro echoto. Kunyungudutsa kushandiswa kwesimba kwe3,000 kW-hr/ton, tungsten kudzoreredza mwero we99%.
Aluminium thermal nzira kuitira kushandisa tsvina tungsten carbide poda tungsten uye cobalt kupatsanurwa kwecobalt kutorwa kweyakagadziridzwa tungsten carbide, yakagadzira aluminium yekupisa nzira yeferro-tungsten process, ine regenerated tungsten carbide nesimbi seyakagadzirwa, aluminium seinoderedza, iyo kushandiswa kwe tungsten carbide mune yayo pachayo kabhoni uye aluminium kupisa kwekupisa, kuitira kuti iyo mbishi mu tungsten uye iron mu ferro-tungsten, inogona kuchengetedza yakawanda magetsi, uye kuderedza mutengo. Panguva imwecheteyo, nekuti iyo tsvina mumbishi tungsten carbide yakadzikira zvakanyanya pane iyo iri mu tungsten concentrate, mhando yechigadzirwa yakakwira kupfuura iyo yeferrotungsten uchishandisa tungsten concentrate seyakabikwa. Iyo yekudzoreredza mwero we tungsten zvakare yakakwira kupfuura iyo yemaitiro uchishandisa tungsten concentrate seyakagadzirwa zvinhu.
