Byiza cyane koresha ivu rike na sulferi nkeya ya bituminiyumu.Gusya byateye imbere, kuvugurura briquetting tekinoroji.Nimbaraga nyinshi nibikorwa byiza.Ibiranga
Ikoresha uburyo bukomeye bwo gukora stem kugirango ikore.Ifite ubuso buhanitse kandi bunini bwa pore.Kugirango ibashe gukuramo molekile yamabara hamwe na molekile itanga impumuro mubisubizo
Dufata ubunyangamugayo na win-win nk'ihame ry'ibikorwa, kandi dufata ubucuruzi bwose tubigenzura kandi tubyitayeho.
