It can be seen that low concentration of ammonia can promote the bacterialeaching.
由此可见，低浓度的氨水对细菌浸矿有促进作用。

By investigating the process mineralogy, the occurrence states of copper in the ore were found out, thus the treatments of sulphidizing flotation and bacterialeaching of copper oxide ore were made.
工艺矿物学研究，查明了矿石中铜矿物的赋存状态，由此制定了氧化铜矿硫化浮选和细菌浸出两种处理工艺。
