The Sangan processing plant consists of four consecutive low-intensity magnetic separation steps with the same magnetic field intensity of 1300 Gauss for upgradation of iron ore. Hence, the iron ore minerals with lower magnetic susceptibility or interlocked with gangue minerals have no opportunity for upgradation, and proceed to the tailing dam. Flotation is a powerful technique for upgradation...

Investigations were carried out on the effective utilization of blast furnace flue dust samples obtained from the two integrated steel plants at Rourkela and Jamshedpur. The samples essentially contained unburnt coke and iron rich grains as the value added products. Flotation technique was employed to recover the carbon values present in the sample. It was possible to obtain a product containin...

molybdenite occurs in five forms in the sar cheshmeh porphyry copper deposit, namely, (1)-veinlets with quartz-molybdenite, (2)-veinlets with quartz-molydenite that were filled with pyrite, (3)-veinlets with quartz-molybdenite-pyrite–chalcopyrite, (4)-molybdenite veinlets with very low quartz and (5)-disseminated molybdenite grains. because of their large size, the veinlet-related molybdenite g...

Recently, coal fly ash has become a potential candidate as secondary resource of rare earth elements (REE). In this investigation, we studied the recovery REE from commercial power plant. The specific aim was to assess technical feasibility recovering using conventional preconcentration methods, including gravity separation, magnetic and froth flotation. experimental results revealed that flota...

This review aims to understand the environmental impact that tailings produce on land and marine ecosystem. Issues related flora, fauna, environment are revised. In first instance, origin of treatment disposal mining waste in Chile other countries is studied. The importance tailings’ valuable elements analyzed through mineralogy, chemical composition, oceanographic interactions. Several treatme...

The ceramic materials industry has vast potential for use of waste from industrial processes, such as iron mining tailings. aim this study was to test technological tailings samples the dam rupture Samarco S.A. Company in 2015 produce structural ceramics. Sedimentation and flotation processes were used improve their characteristics, analyzing chemical mineralogical composition granulometry. We ...
