摘　　要：在新工科背景下,为了探索工程实践教育改革的新路径,加强实践课程的教学,矿物加工研究方法实践课程展开了磷矿正反浮选一系列综合性实验,该实验设计了一次一因素法研究磨矿细度与浮选指标的试验,利用三因素两水平全面析因法考查了正浮选药剂制度对选矿指标的影响,利用登山实验法优化药剂制度,采用单因素法进行反浮选条件实验,进行了开路与闭路流程实验。该综合设计实验能够训练学生的科研动手能力,培养学生新工科背景下学习、锻炼了学生自主设计实验,科研创新和工程实践能力,能够运用正确的思维方法,综合所学专业知识,更为系统地分析与解决所遇到的问题。Under the background of new engineering, in order to explore a new path for the reform of engineering practical education and the practical course of mineral processing research methods, a se-ries of comprehensive experiments on direct and reverse flotation of phosphate rock have been designed. The experiments have been designed to study the grinding fineness and flotation indicators using a one time one factor method. The three factor two level comprehensive factorial method has been used to examine the impact of the positive flotation reagent system on the beneficiation indicators, and the mountaineering experiment has been conducted to optimize the reagent system. Reverse flotation experiments were conducted using a single factor method, and open circuit and closed circuit flow experiments were conducted. This comprehensive design experiment can train students’ scientific research hands-on ability, cultivate students’ ability to independently design experiments, scientific research innovation, and engineering practice under the new engineering background, and be able to use correct thinking methods and integrate professional knowledge learned to more systematically analyze and solve problems encountered.
