2. Nneɛma a wɔde sa yare a wɔboa
Silica gel anhwea ayaresa kwan a edi mũ nso ka nkitahodi ahorow a edidi so yi ho:

Wet reprocessing line a nsu ahwehwɛ anhwea ahosiesie mfiri:
Mfutuma a woyi fi hɔ → Crushing → Magnetic mpaapaemu → Wet reprocessing unit (scrubbing + swirling) → Dewatering → Drying → Cooling → Storage → Mixing.
(Nsuo a wɔde yɛ adwuma foforɔ: Nsuo fĩ → Sedimentation tank → Pressure filter → Fa nsuo a ɛho tew di dwuma bio, wɔde nsuo a ɛyɛ fĩ kɔ.) Nsɛm a wɔaboaboa ano
