【摘要】 以含铟锌精矿氧压酸浸液为原料,利用锌精矿还原Fe3+、中和沉铟方法进行铟的富集。在95℃、锌精矿加入量为理论量3倍、还原120 min条件下,Fe3+的还原率达到96%;中和沉铟时控制终点pH=4.0、温度70℃、时间60 min、通入氮气作为保护气条件下,沉铟后液含铟仅为0.004 g/L,所得铟渣品位在1%左右,铟铁比在8.3左右,铟得到很好的富集。更多还原

【Abstract】 By using the zinc concentrate leaching solution with indium contained as raw material,the precess of riching indium was studied by method of reducing Fe3+ by using the zinc concentrate and neutralizing-prcipitation indium.The results showed that the reducing rate of Fe3+ was 96% for 120 minutes of reduceing time at 95℃ with adding quantity of the zinc concentrate 3 times as the theorrtical need;consistency of indium in liquid after precipitating indium was only 0.004 g/L,the content of indium in precipitate was around 1%,the quality rate of indium to iron in precipitate is about 8.3.更多还原
