Macdanta ManganesHabka Shaqada

Iyada oo la tixgelinayo qaybaha iyo walxaha la xiriira, macdanta manganees waxaa lagu kala qaybin karaa laba nooc - macdanta carbonate ee manganees iyo macdanta manganees oo oksidaysan. Macdanta ugu muhiimsan ee macdanta carbonate ee manganees waa rhodochrosite, calcium rhodochrosite, tetalite iyo oligonite. Qaybta aan ahayn macdanta (gangue) waxaa ka mid ah silicate, carbonate iyo wasakh kale oo ay ku jiraan sulfur iyo bir. Macdanta oxide ee manganees waxaa ka mid ah psilomelane, pyrolusite iyo manganite.
Qaybaha macdanta ee ku jira waa kuwo adag, iyo cabbirka qaybaha manganese-ka waxa uu noqon karaa mid aad u yar, sida dhowr microns, taas awgeed waxa ay adag tahay in la kala saaro macdanta si loo helo diyaarinta heer sare ah.
