摘要
在黄铁矿混合筑堆、顶置筑堆和分层筑堆三种情况下,通过柱浸方式对铀矿石进行微生物浸铀试验,探索微生物浸铀中黄铁矿的最佳筑堆方式。结果表明,混合筑堆、顶置筑堆、分层筑堆的渣计浸出率分别为89.12%、84.37%、85.47%,与顶置筑堆和分层筑堆的柱浸相比,混合筑堆对微生物浸铀具有强化作用。
The uranium ore was bioleached with column leaching in ways of mixture heaping, overhead heaping and segregation heaping. The best way to construct pyrite heap was studied. The results show that the uranium leaching rate of mixture, overhead and segregation heaping is 89.12%, 84.37%, and 85.45 % respectively. Mixture heaping has an invigorating effect on uranium bioleaching compared with o- verhead and segregation heaping.
