The iron content of an iron ore from Anshan is 32.19%. The iron minerals are mainly magnetite and hematite. The gangue minerals mainly include quartz. For this ore, the magnetic separation-reverse flotation tests were conducted for determining process parameters reasonably and guiding development and utilization of such ore. The test In China, the annual discharge of steel slag, red mud, copper slag, and most ferroalloy slag has reached 10–100 million tons; these slags are difficult to be resued due to poor utilization in the fields of cement, concrete, or road pavement. The difficult reusing of these wastes requires new theory and technology, particularly due to the huge Progress and trend of bulk utilization technology of USTB
