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.

Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

Pyrrhotite: The mineral pyrrhotite information and pictures

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

Processing of Nickel Laterite Ores on the Rise

The Move to Nickel LateritesLateritic Nickel Ore ProcessingConclusionSulfides have long supplied the bulk of the global appetite for nickel. But dwindling resources combined with the need to mine at greater (and subsequently less economic) depths to obtain sulfide ores has many miners looking at nickel laterites. Additionally, nickel is expected to see growth in demand as developing economies spur a greater need for stainless steel. Similarly, demand is expected to grow as 在feeco上查看更多信息
