选矿试验报告是选厂设计的重要依据,而选矿试验的试料代表性又直接影响到选矿试验的结论,所以试料代表性是否可靠,将直接影响到选矿厂设计的质量.一项中型多金属矿的选矿试验要6～10位研究人员工作10个月以上,而设计则需各专业的设计人员50～70人工作二年以上.如果试料由于代表 The beneficiation test report is an important basis for the design of a beneficiation plant and the representativeness of the beneficiation test directly affects the conclusion of the beneficiation test. Therefore, whether the representativeness of the test material is reliable or not will directly affect the quality of the design of the concentrator. Metal ore dressing test to 6 to 10 researchers for more than 10 months, while the design requires all professional designers 50 to 70 people working for more than two years if the sample due to the representative
