Is chromite magnetic
Webfine chromite which resulted in this size fraction getting lost to the tailings. Nonetheless, the results are highly favourable to magnetic separation, as the technology is dependent on the fineness of the material. As a result, it is expected that enriching of the chromite by magnetic separation will yield favourable results. WebOct 22, 2024 · The chromite end-member (FeCr 2 O 4) presents a normal spinel structure where each type of cation is situated in their dedicated sites as described above. Chromite is ferromagnetic with a T c of −202.15°C; therefore it does not carry a remanent magnetization at ambient temperature (Ziemniak & Castelli, 2003, Figure 1a).
