矿床工业指标的确定直接影响矿山的开发范围、规模和经济效益。根据四川某斑岩型铜矿床的地质资源条件、开采工艺要求、加工技术性能,拟定了3组矿床工业指标方案。采用地质方案法,在综合考虑市场条件、合理开发利用资源、经济效益和保护环境的基础上,进行方案综合对比,择优推荐矿床的合理工业指标为最低工业品位0.3%、边界品位0.2%。 Determine the industrial indicators of the deposit directly affect the scope of the development of the mine, the scale and economic benefits. According to geological resource conditions, mining technology requirements and processing technology performance of a porphyry copper deposit in Sichuan, three sets of industrial indicators for the deposit have been drawn up. Based on comprehensive consideration of market conditions, rational exploitation and utilization of resources, economic benefits and environmental protection, the reasonable industrial index for the preferential ore deposits is 0.3% of the minimum industrial grade and 0.2% of the border grade.
