Pyrrhotite Processing

Pyrrhotite is named from the Greek word pyrrhos, which means "color of fire".This is despite the fact that the usual color of Pyrrhotite is a bronze color rather than red; however its tarnish may have hints of sparkling red. Pyrrhotite Oxidation Metallurgist & Mineral Processing. Heating Pyrrhotite at 320 degrees C. will destroy its magnetism.

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.

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.

04-09-2017· “Historically, pyrrhotite rejection has been successful by using appropriate reagents, ... “XPS has undertaken size-by-size mineralogical analysis of five different base metal concentrators processing both Ni and Zn orebodies along with extensive flotation testing to identify the behaviour of the two varieties of pyrrhotite.

Pyrrhotite is unusual in that it maintains a variable iron content, as reflected in its odd chemical formula.The variability is formed by deficiencies of iron in its chemical 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 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 processing methods. While the concentrators at Falconbridge and Inco took. similar approaches to the recovery of monoclinic Po, they took quite different routes for treating Po to recover.

Processing of laterites is more energy-intensive since it contains 40% moisture that must be dried. Copper, cobalt, platinum group metals, gold, silver, ... The pyrrhotite is then oxidized to magnetite, and finally to hematite. Eventually some ferric sulfate may form.

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 (Fig. 1.11) is an unusual iron sulfide with variable iron content [Fe (1−x) S (x=0–0.2)].The color ranges between bronze yellow and copper-red with black streak and metallic luster. The hardness varies between 3.5 and 4.5 on the Mohs scale and an average specific gravity of 4.6.

Processing Nickel Ores mine engineerOne Mine's Nickel Processing of Pyrrhoite, Chalcopyrite and Pentalandite Ores , Using wet magnetic separators the magnetic ore is separated (pyrrhotite) and further reduced to 200 mesh in a ball mill Classification is accomplished with screens and cyclon The pyrrhotite is then sent to froth flotation cells, and produces a 3% nickel .FAQ Program for ...

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 ...

01-11-1991· Processing requirements for copper-nickel ores have changed as the need to limit the emission of sulfur dioxide from smelters has gained in importance. Pyrrhotite was once recovered because of its nickel content but now is rejected wherever possible because of the relatively large amount of sulfur that it contributes to the flotation concentrate.
