Mica mbale wosweka mica ndondomeko

1. Kuyandama

Kusanja kumachitika molingana ndi momwe thupi limakhalira komanso mankhwala omwe ali pamwamba pa mica ndi gangue. Ore amaphwanyidwa ndikuphwanyidwa kuti asiyanitse mica monomer. Pansi pa zochita za wothandizira, mica imakhala chithovu ndipo imalekanitsa ndi gangue. Mica flotation imatha kuchitidwa mu zamkati za acidic kapena zamchere. Ma cations aatali a carbon chain acetate amines ndi ma anions amafuta acids ndi omwe amasonkhanitsa mica. Pakuyandama kwa mica, magawo atatu osankha movutikira ndi magawo atatu osankhidwa amafunikira kuti apeze chidwi cha mica. Chifukwa chake, zoyandama za mica ore zimasankhidwa kuti zibwezeretse mica ndi mica-grained mica pansi pa 14 mesh mu pegmatite ndi mica schist. M’dziko langa, kuyandama kwa mica ore sikunagwiritsidwe ntchito popanga.

2. Kupeta

Kupeta kwa Mika kumachitika makamaka kudzera mu zida zapadera. Njirayi nthawi zambiri imakhala: kuphwanya → kuwunika ndi kugawa → kupeta. Mwala ukaphwanyidwa, mica imapangidwa kukhala ma flakes, pomwe mchere wa gangue monga feldspar ndi quartz uli mu tinthu tambirimbiri. Chifukwa chake, magulu amitundu yambiri amagwiritsidwa ntchito kugawanitsa zinthu zosankhidwa kukhala zazikulu zocheperako. Malinga ndi kusiyana kwa liwiro la kuyimitsidwa kwa mpweya, zida zapadera zolekanitsa mpweya zimagwiritsidwa ntchito posankha. Njira yopetera ndi yoyenera madera opanda magwero a madzi ndipo yakhala ikugwiritsidwa ntchito popanga kwenikweni.
