陕西楠木树铅锌矿工艺矿物学

摘要

陕西汉中楠木树矿区氧化铅锌矿矿石量近200万t,矿石中锌的品位为4％左右,铅的品位为1％左右,为了充分利用该铅锌矿资源,本研究采用多种分析检测手段对矿石的化学成分、矿物组成、菱锌矿粒度以及矿石的结构等进行了详细研究,为陕西楠木树氧化铅锌矿选矿工艺的选择和开发提供了理论数据和参考依据.%The ore reserve of Nanmushu lead-zinc ore in Hanzhong Shaanxi is nearly 2,000,000,among which the grade of zinc is about 4％ and that of lead about 1％.In order to fully utilize the resources of the lead-zinc ore,the research on chemical composition,mineral composition,particle size of smithsonite and ore structure was carried on by various means,which provides theoretical and reference data for the choice of mineral processing technology and exploitation of the oxide lead-zinc ore.
