Isesengura ryisoko ryicyuma cya Manganese

Ikibanza cya Manganese gihamye muri rusange, ariko ubutare bwa oxyde nigice cyamajyepfo bizatandukana.Impamvu nyamukuru nizo zikurikira:

1. Kugeza ubu, igiciro cyo kugurisha ku cyambu usanga kiringaniye ugereranije n’igiciro cyo kuhagera, mu gihe cy’amezi menshi akomeje kuzamuka-hejuru, abacuruzi ntibashaka kohereza ku giciro gito;

2. Uhereye ku bihe byashize bigeze hamwe n’iteganyagihe ry’ubwato, icyarimwe mugihe cyo kugabanuka kwububiko bwibiruhuko bwibiruhuko, ibarura ryicyambu rifite amahirwe yo kurushaho kwiyongera, ariko cyane cyane kubirombe bya Afrika yepfo, ibarura ryanyuma rya toni miliyoni 1.42, muribo: Ibirombe bya Afurika y'Epfo muri toni zigera kuri 690000, bingana hafi kimwe cya kabiri cy’ibarura rusange, igice cy’amajyepfo muri toni zigera ku 280000, ikirombe cya Ositaraliya, Gabon ibarura ry’amabuye y'agaciro ya tide agera kuri toni 510000;

3. Nyuma y’ibirori, isubukurwa ry’umusaruro w’inganda zafunzwe hakiri kare muri Guangxi ntirizwi, bitewe n’umuriro w'amashanyarazi n'ibiciro bya alloy.

Mu ncamake, nyuma yiminsi mikuru yimpeshyi, kubera kongera kwiyongera kubarura rusange ryamabuye ya manganese, imyumvire yisoko irashobora kugira ingaruka kumurongo runaka, ariko kubera umubare munini wamabuye yo muri Afrika yepfo mububiko bwibyambu, igipimo cya okiside ubutare ni buto, icyarimwe, kwibanda ku burenganzira bwo gutwara imizigo ni byinshi, kandi ikiguzi cyo gutinda kuhagera ntikiri hasi, ubutare bwa okiside biroroshye kuzamuka.
