Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Pyrite concentrates PCs which contain rich pyrite FeS 2 are solid wastes or byproducts in nonferrous metal production processes such as copper lead and zinc and coal best way to utilize PCs is using roasting process for sulfuric acid production and the solid roasting products can be used as raw materials for iron making [1] To effectively recycle

·1 Introduction Pyrite a mineral with a chemical formula of FeS 2 is an iron disulfide which is usually associated with other sulfides and is abundant in the earth s surface being found in the composition of sedimentary and metamorphic rocks in coal beds and as a replacement mineral in fossils Klein and Hurlbut 1993 There are occurrences of high
·The process was a good alternative to producing sulfuric acid using the sulfur burning process because the operating cost for a pyrite roasting plant was lower than that of a sulfur burning plant
The results show that with increasing microwave treatment time the pyrite in the pulverized coal is first transformed into pyrrhotite and then troilite The order of magnetism in these coal products is as follows Pyrrhotite > Troilite > pyrite In addition the specific magnetization of fine coal first increases and then decreases

·In the flotation of complex sulfide ores a high pH value is generally used to separate valuable sulfide minerals from pyrite or pyrrhotite with xanthate collectors Shen et al 1998 Ball and Rickard 1976 Fig 1 shows that pH values larger than 11 are necessary to markedly depress pyrite flotation in the presence of xanthate collectors The flotation of copper
·The effect of microwave heating on magnetic processing of pyrite was investigated Different size fractions of pyrite were treated heated in a microwave oven at GHz frequency and different power levels The microwave treated pyrite samples of −420 μm fraction were subjected to magnetic separation at magnetic field intensities of
·As one of the crucial factors contributing to coal spontaneous combustion the oxidation of pyrite is a complex process involving multiple reactions particularly in the presence of oxidants Fe3 and O2 and bacteria However experimental results based on mineral pyrite are not entirely applicable to coal pyrite due to their differences in formation environments and
·A considerable amount of waste slag from the pyrite roasting process is produced every year Recovery of iron from the waste slag is of great interest for maximum use of mineral resource
