Pyrrhotite Flotation And Its Selectivity Against . Abstractyrrhotite po is one of the most abundant sulfide minerals in processing industry and must be rejected in most casesarticularly, po rejection and its selectivity against pentlandite pn have long been a challenge due to similarities in the mineral composition of the two minerals and the collectorless flotation characteristics of po.

Pyrrhotite - Wikipedia
Pyrrhotite is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.2). It is a nonstoichiometric variant of FeS, the mineral known as troilite.Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic.The magnetism decreases as the iron content increases, and troilite is non-magnetic.

Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery
15-04-2018 · One of the more common classes of ores containing gold is when gold is associated with pyrite, pyrrhotite, and arsenopyrite. This is the area of gold recovery that has probably received the most research and plant optimization support especially in light of the long history of South African industrial practice. From a reagent viewpoint, charged water soluble collectors such as xanthates ...

01-07-2005 · 1. Introduction. Pyrrhotite is one of the most abundant iron sulfide minerals. It is found in nature to be commonly associated with pentlandite, quartz, ankerite (CaFe(CO 3) 2), pyrite, chalcopyrite, and other sulfide minerals.In many flotation plants, pyrrhotite is rejected to the flotation tailings as a waste product such as in the case of Cu–Ni ores and massive nickel ores (Fornasiero et ...
Pyrrhotite - an overview | ScienceDirect Topics
Pyrrhotite has only been reported once in marine sediments and troilite has not been reported (Rickard and Morse, 2005). The pyrrhotite occurrence was as an overgrowth on magnetite from the Sea of Japan (Kobayashi and Nomura, 1972). Both minerals are rather odd in a marine environment and their association may suggest a higher temperature source.
Pyrrhotite: The mineral pyrrhotite information and …
Pyrrhotite is unusual in that it maintains a variable iron content, as reflected in its odd stone formula.The variability is formed by deficiencies of iron in its stone structure, which is also responsible for its magnetic properties. Greater deficiency of iron is responsible for stronger attraction to magnetic fields. If the mineral lacks any iron deficiencies, it is no longer ...
PYRRHOTITE (Iron Sulfide) - Amethyst Galleries
When pyrrhotite is low in sulfur and the formula is closer to true FeS, then the structure is hexagonal. But when it is high in sulfur, the structure is monoclinic. Clearly two different symmetries, two different formulae; therefore, two different minerals . . . except, that in natural pyrrhotite crystals both phases are present in the same crystal.
