Ningxia anthracite yo mu rwego rwohejuru (ivu ridasanzwe, sulfuru nkeya, fosifore nkeya, karubone ihamye cyane, agaciro ka calorifike) ibarwa kuri 1200 ℃, hamwe na okiside ikomeye, imbaraga za mashini nyinshi, ibikorwa bya shimi nyinshi, umuvuduko mwinshi wo kugarura amakara nibindi ibiranga. Ikoreshwa cyane cyane mu kongera karubone mu gukora ibyuma. Igikorwa cyayo nukuzamura ubushyuhe vuba, hamwe ningaruka nziza nigipimo gihamye cya karubone. Irashobora gukoreshwa muguhindura ibirimo karubone hamwe na ogisijeni yibyuma byashongeshejwe, guhindura ubukana bwayo nubukomere, bityo bikazamura ubushobozi bwa nucleation yicyuma gishongeshejwe hamwe nubwiza bwimbere bwa bilet.
