This paper describes a geometallurgical approach for predicting separation performance of a mineral deposit that is applicable to existing operations and projects in the early stage of mine development. The method includes a class-based analysis to understand the variability in geological and mineralogical characteristics, class-based modelling to understand the influence of these characteristics on separation performance, and process performance domaining to develop domains related to separation performance and to understand the variability in separation response. The application of the approach in a copper–gold porphyry deposit has improved the prediction of copper recovery by flotation compared to the feasibility study models. The method showed that copper assay is not the only factor affecting copper recovery but has identified geological and mineralogical factors that influence flotation response. Overall, the geometallurgical approach is shown to be beneficial in assessing geological, mineralogical and processing variability within the deposit. This understanding of the variability is helpful in the design of an efficient metallurgical testwork program, and also provides valuable information for process optimisation.

一种预测分离性能的地质冶金方法

本文介绍了一种用于预测矿床分离性能的地质冶金方法,该方法适用于矿山开发早期的现有作业和项目。该方法包括基于类别的分析以了解地质和矿物学特征的可变性,基于类别的建模以了解这些特征对分离性能的影响,以及过程性能域化以开发与分离性能相关的域并了解分离反应。与可行性研究模型相比,该方法在铜金斑岩矿床中的应用提高了浮选法铜回收率的预测。该方法表明,铜含量测定不是影响铜回收率的唯一因素,但已经确定了影响浮选响应的地质和矿物因素。总的来说,地质冶金方法被证明有利于评估矿床内的地质、矿物和加工变异性。这种对可变性的理解有助于设计高效的冶金测试工作程序,也为工艺优化提供有价值的信息。
