Experiment on Optimization of Comprehensive Recovery Process of a Tungsten Ore in Inner Mongolia
摘要
Abstract
A tungsten ore in Inner Mongolia contains fluorite resources.Due to the loss of fluorite in the original process of fatty acid tungsten flotation and the influence of magnetic gangue,the comprehensive recovery of fluorite is low and the grade of fluorite concentrate is insufficient.In this study,GY 109 hydroxamic acid was used instead of fatty acid to reduce the loss of fluorite in tungsten flotation process,and the influence of magnetic gangue on the quality of fluorite concentrate was reduced by strong magnetic waste disposal.Tungsten concentrate with WO3 grade of 31.41％and tungsten recovery rate of 80.94％and CaF2 fluorite concentrate with grade of 97.26％and fluorite recovery of 62.73％were obtained.Effective recovery of tungsten was realized and acid grade fluorite concentrate was obtained from the tailings.By ptimizing the comprehensive recovery process of tungsten ore containing fluorite the comprehensive utilization rate of resources was improved.关键词
