摘　　要：对某氧化锌矿进行了多元素分析及物相分析,结果表明该矿石品位低、氧化率高、泥化严重,属于极难选的低品位高钙型氧化锌矿.根据该矿的工艺矿物学特征,进行了泥砂分选试验研究.研究结果表明适当的脱泥量是保证锌精矿浮选指标的重要因素.The oxided zinc ore is employed for chemical analysis and phase analysis,the results suggest that the ore is with low grade,high oxidation rate and serious slime,so it is refractory oxided zinc ore of low grade and high calcium content.According to the process mineralogy characteristics of the ore,separation possibility of slime and sand is then tested,and the results show that appropriate desliming amount is an important factor to ensure the grade and recovery of zinc concentrate.
