Iron Ore Processing From Pyrite Pyrite Mining Processing Equipment Flow Chart Cases Pyrite is used to create iron sulfate that is used to make nutritional supplements, ink, lawn conditioner, water treatment and flocculation, moss killer, and many other chemical processes.
· Extraction of nonferrous metals is accompanied by processing a considerable volume ore raw material. For example, in order to produce one ton of copper on average it is necessary to process up to 20 tons of rock mass, whose dumping creates technogenic formations that are main sources of contamination of water bodies, the air basin, and adjacent earth.
R. Dunne, in Gold Ore Processing (Second Edition), 2016 7.3 Flotation of Gold-Carrying Iron Sulfides Pyrite is known to be oleophilic when the surface is free of oxidation products (Kocabag et al., 1990), but it is nevertheless necessary to use a collector to float

· Processing plants for porphyry copper ores are generally very large, processing up to 200,000 tpd of ore (JX Nippon, 2018)), and emphasis is put on throughput. Ores with low pyrite content (<2%) are generally considered easier to process (and the reagents scheme only includes copper collectors, pH regulator, and frother).

Iron pyrite is a naturally pure and hugely useful ore of iron, finding applications in areas as diverse as photovoltaic cells, brake pads and as a glass colourant. African Pegmatite is a leading supplier of iron pyrite, with the ability to provide the material in a range of grind sizes suited to any operational need.
Pyrite ore Processing Flow Sheet and Beneficiation Plants. The main composition of pyrite is FeS2, kind of raw material to produce vitriol. And it can be used as filler because of its big density of 4.9-5.2g/cm3. Pyrite is mainly concentrated by gravity separation.

· This is in contrast to areas dominated by high-grade epithermal-stage mineralization where pyrite grains are As- and Au-rich throughout and thus require longer oxidation and processing time. Understanding Au deportment in telescoped deposits is therefore essential for optimizing mineral processing and can significantly impact the economics of mining complex hybrid ore deposits.
