Isesengura ryisoko ryicyuma cya Manganese

Ubutare bwa Manganese muri rusange butajegajega, ariko ubutare bwa oxyde nigice cyamajyepfo bizatandukana.Impamvu nyamukuru nizo zikurikira:

1. Kugeza ubu, igiciro cyo kugurisha icyambu kiringaniye cyane ugereranije nigiciro cyo kuhagera, mugihe cyamezi menshi yikurikiranya-hejuru, abacuruzi ntibashaka kohereza kubiciro buke;

2. Uhereye ku bihe byashize bigeze hamwe no guteganya imbonerahamwe y'ubwato, icyarimwe mugihe cyo kugabanuka kwububiko bwibiruhuko bya Spring Festival, kubara ibyambu bifite amahirwe yo kurushaho kwiyongera, ariko cyane cyane kubirombe bya Afrika yepfo, ibarura ryanyuma rya toni miliyoni 1.42, muribyo: Ibirombe bya Afrika yepfo muri toni zigera kuri 690000, bingana hafi kimwe cya kabiri cyibarura rusange, igice cyamajyepfo muri toni zigera kuri 280000, ikirombe cya Ositaraliya, Gabon ibarura ryibanze rya toni zigera kuri 510000;

3. Nyuma y’ibirori, gusubukura umusaruro w’ibihingwa byafunzwe hakiri kare muri Guangxi ntibizwi, bitewe n’amashanyarazi n’ibiciro bya alloy.

Muri make, nyuma yumunsi mukuru wimpeshyi, kubera kongera kwiyongera kubarura rusange ryamabuye ya manganese, imyumvire yisoko irashobora kugira ingaruka kumurongo runaka, ariko kubera ubwinshi bwamabuye yubutare bwa Afrika yepfo mububiko bwicyambu, igipimo cya okiside ubutare ni buto, icyarimwe, kwibanda ku burenganzira bwo gutwara imizigo ni byinshi, kandi ikiguzi cyo gutinda ntikiri hasi, ubutare bwa okiside biroroshye kuzamuka.
