某低品位难选金矿选矿厂流程考察及诊断

The Investigation and Diagnosis on Whole Mineral Process Flow of One Low-grade and Refractory Gold Ore

为了查找某低品位难选金矿选矿厂工艺存在问题,开展了全流程工艺考察、工艺矿物学研究和流程诊断。查明了原矿性质、各产物的工艺矿物学特性、各作业的工艺技术指标和各粒级金的回收率。分析了矿石难选原因、工艺矛盾和问题,提出了改进措施和工艺优化的研究方向,为该选矿厂进一步优化工艺和提高选矿指标提供了科学依据。

In order to find out the problem of a low grade refractory gold ore of plant, we have made progress in some aspects such as completing the whole flow process investigation and diagnosis and research of process mineralogy. The ore properties, the process mineralogy characteristics of various products, the technical indexes of each operation and the gold recovery of each particle size were identified. The reasons for the refractory mineral processing, the contradiction in process and the problem were analyzed. The research direction of improvement and optimization in the process were propounded,which provided the scientific basis for further improvement and optimization in the mineral processing index.
