摘要
开发了一种低温低压处理硫化锌精矿的新工艺,并对闪锌矿和铁闪锌矿2种锌的主要硫化矿物进行了浸出行为的比较。结果表明,在115℃,500kPa条件下2种矿物锌浸出率均大于97%,硫90%转化成了元素硫,但相同条件下2种矿物浸出液中铁含量具有显著差异。
A new technology has been developed to treat zinc sulphides at low temperature and pressure, and the leaching behavior of sphalerite and marmatite that are the two main minerals of zinc sulphide have been compared. The results show that the zinc extraction of both minerals can reach more than 97% and 90% sulphur converts into elemental. However, in the same leaching condition, the concentrate of iron in solution exist much difference between the two minerals.
