Ningxia anthracite yo mu rwego rwohejuru (ivu ridasanzwe, ivu rya sulferi nkeya, fosifore nkeya, karubone ihamye, agaciro gakomeye ka calorifique) ibarwa kuri 1200 ℃, hamwe na okiside ikomeye, imbaraga za mashini nyinshi, ibikorwa bya shimi nyinshi, umuvuduko mwinshi wo kugarura amakara nibindi biranga. Ikoreshwa cyane cyane mu kongera karubone mu gukora ibyuma. Igikorwa cyayo nukuzamura ubushyuhe vuba, hamwe ningaruka nziza nigipimo gihamye cyo kwinjiza 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.
