Jan 06, 2011 To separate the phases, the magnetic separation of reducing products at H = 40 and 80 kA/m is used. The best characteristics are attained upon roasting the ore with a reducing agent and a sulfidizing agent at t = 1300 C. In this case, the magnetic fraction contains 7.1% Ni, while the nonmagnetic one contains 0.18% Ni.

This may involve a magnetic separation step up stream, and then independently processing a magnetic (high sulfur) and a non-magnetic (low sulfur) pyrrhotite stream [22]. The results of this study have shown that the non-magnetic Sudbury CCN pyrrhotite was relatively unreactive towards oxidation and consequently showed good floatability.
