摘要
在技术经济初步分析的基础上探讨了预选工艺对某银铅锌矿开发效益的影响。与无预选的浮选工艺比较，预选工艺可大大提高资源净价值，产值利税率可从９．７７％提高到１９．８６％。
Effect of the preconcentration technology on the development economic benefits of the deposit is discussed in this paper based on the technological and economic analysis. Through preconcentration, there is an great increase of the net value of the resources over the flotation process with no preconcentration, and the ratio of profit to output value increases from 9.77% to 19.86%.
