根据对河北省唐山市马兰庄铁矿矿石性质的研究结果以及对类似选厂的考察,设计马兰庄铁矿选矿厂。该设计为一次建厂,建厂规模为年处理量60万吨原矿石,根据地形考察报告设计为依山坡建厂,破碎位于同一等高线,主厂房依山坡地势而建。矿石为中等硬度,原矿最大粒度为500mm,含水量为2%,含泥量小于1%。采矿废石混入10%。,。采用三段一闭路破碎流程。为了达到更好的选矿效果,采用阶段磨矿阶段选别的流程。原矿品位30%,经过四次磁选后精矿品位可达到66%,回收率为85%,%。,。

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 t / cubic meters, 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 ic separation concentrate grade can be achieved after the 66 percent response rate was 85 percent, the yield was percent. This design is expected to total investment of about million yuan, the payback period is years.
