Nkuko ibirungo bya Sn birimo birenga 95% mubicuruzwa bitagira isasu bya SnAgCu, bityo rero ugereranije nuwagurishije gakondo, kwiyongera kwibigize Sn hamwe nubushyuhe bwibikorwa byo kugurisha bidafite isasu bizatuma okiside yuwagurishije yiyongera .Byambere kugabanya okiside yuwagurishije slag, dross, tugomba mbere na mbere gusobanukirwa ubwoko nuburyo bwo kubumba.
Ibice bitatu bikurikira bizasuzumwa:
.Nkuko bigaragara hano hepfo:
.Nkuko bigaragara ku gishushanyo gikurikira:
.
Ibisigazwa by'ibishyimbo byatewe nigitutu cyiza cya ogisijeni yogosha, hamwe ningaruka zamazi muguhuza ibisubizo bitandukanye, inzira yihariye niyi ikurikira ：
Agace kirabura ni ikirere cyikirere, ubushyuhe bwamazi bugabanuka cyera Sn.t = t3 igishushanyo dushobora kubona igice gito cyumuyaga cyamizwe kumuti wabagurishije, igice gito cyumwuka bitewe na okiside yihuse ya ogisijeni imbere mumabati izagaragara ariko ntishobora gukuraho gaze ya N2, bityo ikora imipira yubusa , Kubera ko ubucucike bwumupira wubusa ari buto cyane kuruta ubw'amabati, ubuso bwamabati bugomba kugaragara mugihe uyu mupira wubusa umaze gutondekwa kugirango ube ureremba hejuru y amabati asigaye ya Bean.
Kumenya ibitera nubwoko bwamabati, twizera ko kugabanya imiterere yibisigazwa byibishyimbo bya Bean ari ukugabanya kugurisha amabati ya tin slag ingamba zifatika.Uhereye hejuru byavuzwe haruguru birashobora kugaragara inzira igenda neza: umwobo wimipira yagurishijwe nibintu bibiri bikenewe ：
Ikintu cya mbere gisabwa ningaruka zimbibi, hejuru y amabati hamwe numuzingo udasanzwe, ukora fagocytose.
Icya kabiri gisabwa ni umupira wuzuye imbere kugirango ukore firime yuzuye ya okiside, gaze ya azote ikorwa mubipaki.Bitabaye ibyo, ireremba hejuru yuwagurishije mugihe umupira wuzuye uzavunika, udashobora gukora "ibisigazwa byibishyimbo."
Ibi bintu bibiri bikenewe ni ngombwa.
Ingamba zo kugabanya imyanda mu kugurisha imiraba yerekana ibi bikurikira:
1.Kugabanya icyuho cyatewe mugihe uhinduranya umuraba, bizagabanywa kugurisha ibicuruzwa kugurisha imbaraga kugirango ugabanye umuzingo, bityo bigabanye kubyara fagocytose.
Twahinduye rero igice cyambukiranya inkono yagurishijwe mo trapezoid, hanyuma dukora umuraba wa mbere uko bishoboka kwose hafi yinkono yuwagurishije
2. Muri byombi byombi byambere hamwe numurongo wa kabiri twongeyeho igikoresho cya barrière idafunguye kubagurisha-gutemba.
3. Fata uburinzi bwa N2 kugirango wirinde kubyara ibibyimba bya okiside yuzuye mumupira ugurisha.
