金矿石加工及测试质量过程控制

Quality control of gold ore processing and testing

目前对金矿石加工的质量要求越来越高,因此需要在加工过程中对其进行质量测试,保证加工质量的准确度。但在实际金矿石加工测试的工作中,存在着矿石成分的复杂性提高了加工难度;矿石中伴生较多的其它元素,其对测试的准确性具有较大的干扰作用;测试时间短,并且结果需要满足相关矿石测试规范的要求;测试样品加工处理难,均匀性和代表性对测试结果影响较大;测试过程中的不确定度对结果也有一定的影响等问题。本文介绍了样品加工过程中不均匀性、测试过程中不确定等的影响因素,并针对样品均匀性、代表性、测试过程控制三个方面进行了对策分析。

At present,the quality requirements for gold ore processing are getting higher and higher,so it is necessary to carry out quality testing during the processing to ensure the accuracy of the processing quality.However,in the actual gold ore processing test,the complexity of the ore composition increases the difficulty of processing;the other elements associated with the ore have a greater interference effect on the accuracy of the test;the test time is short,and The results need to meet the requirements of the relevant ore test specifications;the test sample processing is difficult,the uniformity and representativeness have a great impact on the test results;the uncertainty in the test process also has a certain impact on the results.This paper introduces the influencing factors such as the inhomogeneity during sample processing and the uncertainty during the test process,and analyzes the countermeasures for three aspects：sample uniformity,representativeness and test process control.
