【摘要】：层次分析法在决策分析中有着广泛的应用,为了尝试证明层次分析法可有效对选矿厂选矿工艺进行决策评价,探讨层次分析法在选矿工艺决策过程中的可行性,针对广西某碳酸盐型低品位锰矿,在已有的试验研究的基础上,通过尝试采用层次分析法(AHP)对五种选矿方案分别从精矿的品位、回收率和产率三个方向进行评价,对各矩阵的赋值以试验结果为依据进行赋值打分确定,得出各层级因素的权重并进行分析。结果表明,单排序及总目标排序具有满意的一致性,在先考虑在保证品位的情况下,应该选取磁选作为最佳的选矿工艺。在考虑品位为最重要的指标,应该选择磁选+反浮选作为最佳的选矿工艺,结果同原有试验研究结果基本符合,表明层次分析法用于选矿工艺决策是可行的。
[Abstract]:The analytic hierarchy process has a wide application in decision analysis. In order to try to prove that the analytic hierarchy process can effectively make a decision-making evaluation on the ore dressing process of the ore dressing plant, the feasibility of the analytic hierarchy process in the decision-making process of the ore dressing process is discussed, and the low-grade manganese ore of a certain carbonate type in Guangxi, On the basis of the existing test research, by using the analytic hierarchy process (AHP) to evaluate the grade, the recovery rate and the yield of the concentrate, the assignment of each matrix is determined based on the test results. And the weight of each level factor is obtained and analyzed. The results show that the single-order and the total target ordering have the satisfactory consistency, and in the case of ensuring the grade, the magnetic separation should be selected as the best ore-dressing process. In order to consider grade as the most important index, the magnetic separation and reverse flotation should be selected as the best ore dressing process, and the result is basically in accordance with the original test results, which indicates that the analytic hierarchy process is feasible for the decision making of the ore dressing process.
