Iron ore concentrate sales in a mineral processing plant appeared a trend of high sulfur, exceeding the sales requirement of 0.3% significantly. To this end, for the sulfide in iron concentrate mainly exists in the form of pyrrhotite, companies with iron minerals and has a high degree of oxidation, we can add flotation agent to the magnetic separation column, and at the same time fill gas for s...

A novel approach is developed for desulphurization of fuels or organics without use of catalyst. In this process, organic and aqueous phases are mixed in a predefined manner under ambient conditions and passed through a cavitating device. Vapor cavities formed in the cavitating device are then collapsed which generate (in-situ) oxidizing species which react with the sulphur moiety resulting in ...

Coal desulfurization prior to usage is frequently subjected preprocessing achieve clean fuel and reduce environmental impacts. In this study, of Mach coal Balochistan was investigated with different leaching solvents. The solvents used are NaOH HNO 3 . Effects particle size solvent weight% on sulfur removal were studied, whereas the temperature agitation time kept constant. Desulphurization exp...
