The contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore processing This study utilized froth flotation to float pyrrhotite away from magnetite using collectors of xanthate and dixanthogen It was found that xanthate or dixanthogen alone could not achieve selective separation between pyrrhotite and magnetite in
Keywords High voltage electrical pulses Grindability Coarse particle flotation Desulfurization Iron ore 1 Introduction Iron is one of the most common elements in the earth s crust which nowadays is considered for processing due to the grade decreasing of iron ores and the increase of associated impurities such as sulfur [1] The
Direct application of high sulfur fuels and ores can cause environmental pollution such as air pollution and acid rain and in serious cases endanger human health and contribute to property damage In the background of preserving the environment microbial desulfurization technologies for high sulfur fuels and ores are rapidly developed This paper
China is rich in total reserves of iron containing mineral resources; however the average grade of iron ore in China is not competitive with that in Australia and Brazil [19] which was mainly beneficial to flotation desulfurization And the fineness of second stage grinding was 90% 95% −44 μm in order to meet the particle size
The results in optimal conditions indicated that column flotation was considerably efficient for iron ore desulfurization so that a high purity concentrate with the sulfur content of % and
