摘　　要：以钨矿选矿工艺决策为例,应用层次分析法构建了层级结构模型。将层次结构分为目标层、准则层和方案层,从产品回收率、产品品位、工艺成本、流程结构4个方面,定量计算了全重选、全浮选、重选-浮选3种工艺的综合排序向量。结果表明,3种工艺的优劣排序为:重选-浮选>全浮选>全重选,即重选-浮选流程具有明显优势。实践证明层次分析法应用于钨矿选矿工艺决策是可行的。Analytic hierarchy process （ AHP ） was applied to create a hierarchical structure model for decision-making in optimization of tungsten ore benefieiation process. The hierarchical structure was divided into a target layer, a standard layer and a scheme layer. The comprehensive ranking vectors of three processes including full gravity separation, full flotation, and gravity separation-flotation were calculated with AHP in terms of recovery, grade, process cost and process structure. Results showed that flowsheet of gravity separation-flotation has obvious advantages as it ranks number one according to the final evaluation of vectors, followed sequentially by lull flotation and lull gravity separation. The study shows that AHP is feasible for process decision-making in tungsten ore benefieiation.
