年处理15万t/a风积沙中长石与石英的浮选工艺初步设计(含CAD图)(任务书,开题报告,外文翻译,论文说明书13500字,CAD图纸8张)
摘要
在地壳中,长石和石英这两种造岩矿物分布均很广泛,储量丰富,用途很多,可应用于建材、玻璃陶瓷、电子电器及耐火材料等诸多领域。随着国民经济的快速发展,各产业均调整结构,对长石石英的需求量大大提高,同时各行业对长石石英原料的质量标准也不断提升。目前,我国对长石和石英的开采利用主要集中在各地优质长石石英矿床,大量中低品级矿床并未得到有效的开发利用。而风积沙储量较大,但品位相对较低,因此,设计出经济合理的风积沙选矿厂是十分必要的。本文根据国内外现有风积沙实验研究报告和实践经验,设计出15万吨/年的风积沙选矿厂。其中,选矿工艺流程包括筛分抛尾工艺流程,一段磨矿工艺流程,强磁除铁工艺流程,脱泥工艺流程,一段粗选流程,两段精选流程。根据原始资料计算出各个工艺流程中有用矿物的品位、矿浆含水量、补加水量等,再由计算结果选择合适的设备型号,画出合理并且符合实际情况的工艺流程图、选矿的数质量流程图、选矿设备的联系图、筛分车间的工艺布置图和磨浮车间工艺布置图。

Abstract
In the earth's crust, feldspar and quartz, two petrogenetic minerals are widely distributed, rich in reserves and have many USES.With the rapid development of the national economy, various industries have adjusted their structures, and the demand for feldspar quartz has been greatly increased. Meanwhile, the quality standards for feldspar quartz raw materials in various industries have been continuously improved.At present, the exploitation and utilization of feldspar and quartz in China are mainly concentrated in high-quality feldspar quartz deposits in various regions.The wind-accumulated sand reserves are large, but the grade is relatively low. Therefore, it is necessary to design a reasonable and economical wind-blown sand concentrator.Based on the research report and practical experience of wind-sediment experiment at home and abroad, a 150,000-ton/year wind-sediment concentrator was designed in this paper.Among them, the process flow of ore dressing includes the process flow of sieve separation and tail-throwing.A section of grinding process flow, strong magnetic iron removal process flow, mud removal process flow, a section of rough selection process, two sections of selection process.According to the original data, the grade of useful minerals, the moisture content of slurry and the amount of water added in each process are calculated.According to the calculation results, the appropriate equipment model is selected.Draw a reasonable and practical process flow chart, the number and quality flow chart of ore dressing, the connection diagram of ore dressing equipment, the process layout of the screening workshop and the process layout of the grinding and floating workshop.
