Indlela ye-Agglomeration Isithando sombane somlomo ovulekileyo esinokushukunyiswa kumzila kaloliwe kunye necandelo eliphezulu lomzimba wesithando somlilo linokusetyenziswa, kwaye ikhabhoni isetyenziswa njenge-arhente yokunciphisa. I-ore ye-tungsten entle, i-asphalt coke (okanye i-petroleum coke) kunye ne-agent ye-slagging (i-bauxite) eyenziwe ngumxube wentlawulo edityaniswe kwiziko kwiibhetshi enye emva kwenye, isinyithi esisulungekisiweyo esithandweni sihlala sibonakala, kunye nobunzima obuphezulu, indawo esezantsi yokuqina ngokuthe ngcembe. Ukuqokelelana kwesithando somlilo emva kokumisa isithando somlilo, ukutsala umzimba wesithando somlilo ngaphandle, susa icandelo eliphezulu lomzimba wesithando somlilo ukwenzela ukuba i-condensation iqhume. Emva koko thatha ii-agglomerate zokutyumza kunye nokugqiba; khetha imiphetho, kunye ne-slag kunye namacandelo angafanelekanga abuyele kwisithando somlilo ukuze ahlaziye. Imveliso iqulethe malunga ne-80% ye-tungsten kwaye ayikho ngaphezu kwe-1% yekhabhoni.
Indlela yokutsalwa kwentsimbi ilungele ukunyibilikiswa kwe-ferro-tungsten equlethe i-70% ye-tungsten enendawo esezantsi yokunyibilika. I-silicon kunye nekhabhoni zisetyenziswa njenge-reductants; isetyenziswa kwizigaba ezintathu: ukunciphisa (ekwabizwa ngokuba yi-slag depletion), ukucocwa kunye nokutsalwa kwentsimbi. Iziko lenqanaba lokunciphisa liqulethe iziko lokuthatha intsimbi eshiywe ngasemva emva kwe-slag equlethe i-WO3 enkulu kune-10%, kwaye ngokulandelelana yongezwa kwi-tungsten concentrate charge, kwaye yongezwa kwi-silicon 75% ferrosilicon kunye nenani elincinci le-asphalt coke (okanye i-petroleum coke) yokunciphisa ukunyibilika, ukuba ibe yi-slag equkethe i-WO3 ukuya kwi-0.3% ngaphantsi kwe-slag. Emva koko idluliselwe kwinqanaba lokusulungekiswa, ngeli xesha, ukongeza i-tungsten concentrate, umxube we-asphalt coke kwiibhetshi, ezisebenza ngombane ophezulu, kwiqondo lokushisa eliphezulu ukususa i-silicon, i-manganese kunye nezinye izinto ezingcolileyo. Uvavanyo lwesampuli ukumisela ukubunjwa abaqeqeshiweyo, waqala ukuthatha intsimbi. Ngethuba lexesha lokukhutshwa kwesinyithi, i-tungsten concentrate kunye ne-asphalt coke yongezwa ngokufanelekileyo ngokwemiqathango yesithando somlilo. Ukusetyenziswa kwamandla okunyibilikisa malunga ne-3,000 kW-hr /ton, izinga lokubuyisela i-tungsten malunga ne-99%.
Indlela yokushisa ye-aluminium ukuze kusetyenziswe inkunkuma ye-tungsten carbide powder tungsten kunye ne-cobalt yokwahlula i-cobalt yokukhutshwa kwe-tungsten ehlaziyiweyo ye-tungsten carbide, iphuhlise indlela yokufudumala ye-aluminium yenkqubo ye-ferro-tungsten, kunye ne-tungsten carbide ehlaziyiweyo kunye nentsimbi njengezinto ezikrwada, i-aluminium njengento yokunciphisa, ukusetyenziswa kwe-tungsten carbide kwikhabhoni yayo kunye ne-aluminium yokutsha kobushushu, ukwenzela ukuba izinto eziluhlaza kwi-tungsten kunye nentsimbi zibe yi-ferro-tungsten, kunokonga umbane omningi, kunye nokunciphisa iindleko. Kwangaxeshanye, ngenxa yokuba ukungcola kwi-tungsten carbide ekrwada kusezantsi kakhulu kunezo zikwi-tungsten concentrate, umgangatho wemveliso uphezulu kunolo we-ferrotungsten usebenzisa i-tungsten concentrate njengemathiriyeli ekrwada. Izinga lokubuyisela i-tungsten liphezulu kunelo lenkqubo yokusebenzisa i-tungsten concentrate njengezinto eziluhlaza.
