| 中文摘要: |
| 我国低品位的多金属矿床较多,单独开发其中的任何一种矿产都可能不具有经济意义,但通过论证综合品位指标对共伴生矿产进行综合勘查,就可能具有经济开发意义。为了充分合理地综合勘查共生、伴生矿产,文章分析了矿床工业指标的构成要素及其选取条件,以广西南丹矿黑水沟-大树脚矿段锌多金属矿为例,提出了四套不同的工业指标方案,论证了综合品位指标,并圈出了矿体,估算了矿产资源量。通过对比分析可以看出,确定合理的最低综合品位指标要全面考虑矿体特征、选矿回收率、开采的经济效益等因素。采用最低综合品位指标圈矿有利于我国共伴生矿产的综合勘查评价、综合开发利用,有利于估算可靠的资源量,对矿产资源评价有重要的作用。 |

| There are many low-grade polymetallic deposits in China,so it may be uneconomic to develop any of them alone.However,it may be economical to use comprehensive grade index to conduct comprehensive exploration of associated minerals.In order to make rational use of symbiotic and associated minerals,the paper analyzes the composition elements and selection conditions of the industrial indicators of the deposit.Taking the zinc polymetallic ore in Heishuigou-Dashujiao of Nandan deposit in Guangxi as an example,four different industrial index schemes are proposed,the comprehensive grade index is demonstrated,the ore body is circled and the mineral resources are estimated.Through comparative analysis,it can be seen that the determination of reasonable minimum comprehensive grade index should comprehensively consider the characteristics of ore body,mineral recovery rate,economic benefits of mining and other factors.The use of the lowest comprehensive grade index is conducive to the comprehensive exploration,evaluation,comprehensive development and utilization of the associated minerals in China,and is conducive to the estimation of reliable resource reserves,which plays an important role in the evaluation of mineral resources. |
