摘要/Abstract

摘要： 矿冶工程中，地质品位、采出品位、入选品位、精矿品位、入炉品位是互为条件、相互联系的，对其进行实时动态优化是“五品联动”矿冶工程管理模式的基础。本文通过考察开采、配矿、选矿和冶炼过程中的品位与产量关系，推导出各阶段的品位与成本的关系模型，并在该模型的基础上进行边际分析，得出各阶段的品位-成本边际模型。建立了相应的品位-链接成本关系模型，并此基础上提出了品位-成本边际指数。最后，提出了五品联动的品位优化方法并给出具体步骤。文中还应用鞍钢矿业的实际数据进行了公式计算，结果和实际生产的情况吻合。

关键词: 品位, 边际成本, 品位-成本边际指数, 品位优化

Abstract: In mining metallurgical engineering, the geological grade, mining grade, feed grade, concentrate grade and charged grade are reciprocal and interactive and the dynamic optimization of them is basic to the "five grades ganged" engineering management mode. Firstly, the grade capacity relationship in the production stages is analyzed, including mining, ore blending, beneficiation and smelting. The grade-cost relationship model and the related grade-cost marginal model are derived. The grade chained cost models are then built and a Grade-Cost Marginal Index (GCMI) is also proposed. At last, a "five grades ganged" optimization method is developed to adjust the grades.A series of numerical samples from the Ansteel Mining are applied to the modes to compute the practical analysis results which are all reasonable to the production situation.

Key words: grade, marginal cost, Grade-Cost Marginal Index (GCMI), grades optimization
