Millerite (NiS) is one of the less common nickel-bearing minerals that is typically formed as a replacement for pentlandite. Due to the scarcity of millerite, its flotation behavior is not well understood in literature. In this study, the surface properties of millerite were investigated. Cyclic...

This thesis is mainly concerned with understanding the flotation behaviors of the polymorphic pyrrhotite (Fe1-xS, 0 < x ≤ 0.125) and pentlandite ((Ni,Fe)9S8) to find better measures for their flotation separation. The flotation separation of pentlandite from pyrrhotite is a complicated issue due...
