Abstract
According to the inspection of Malanzhuang iron ore in Tangshan, Hebei Province, nd the nature of the findings of similar election plant inspection, design Malanzhuang iron ore concentrator. The design for a construction, construction of the largest of the handling capacity of 600,000 tons of ore, according to topography inspection report is designed to build factories on the slope, broken in the same contour, the main plant built by a mountain slope potential. Ore for the middle hardness, the largest ore for the size 500 mm, the water content of 3 percent, with mud in less than one percent. Mining waste rock mixed with 10 percent. Density of 3.26 t / cubic meters, 1.5 degrees loose. Using a three-house broken processes. In order to achieve better results processing, grinding stage by stage another election process. Ore grade of 30 percent, after four magnetic separation concentrate grade can be achieved after the 66 percent response rate was 85 percent, the yield was 38.64 percent. This design is expected to total investment of about 38.3533 million yuan, the payback period is 1.12 years.
