选矿技术经济指标的确定,是生产矿山资源评价的基础。结合对石人沟铁矿露采境界内超贫矿合理利用的研究,通过对选矿技术指标的确定和应用及获取这些指标的方法的初步分析,找出了一些规律。认为选矿技术指标的确定必需具有针对性、实践性、系列化,可通过生产统计法、试验法和理论分析法获取,结果与生产实际相符,满足了要求。
Mineral processing technology to determine the economic indicators is the basis for the production of mine resources evaluation. Based on the research on the reasonable utilization of ultra-lean ore in the mining area of Shirengou iron mine, some laws were found out through the preliminary analysis of the determination and application of ore dressing technical indexes and the methods of obtaining these indexes. It is considered that the determination of beneficiation technology indexes must have pertinence, practicality and serialization, which can be obtained through the methods of production statistics, experiment and theoretical analysis. The results are consistent with the actual production and meet the requirements.
