从软锰矿与黄铁矿硫酸浸出渣中回收硫磺的研究

Studies on the Recovery of Sulfur from the Leach Residue of Pyrolusie and Ironpyrite

研究了从软锰矿与黄铁矿在硫酸介质中浸出生产硫酸锰的浸出矿渣中提取回收硫磺的方法和条件。采用硫化铵溶液为浸提剂能有效地提取矿渣中的硫磺。以及讨论了浸提剂用量、浸提时间。

Studies on the recovering method and conditions of sulfur from the leach residue in an acid medium after leaching manganese sulfate from pyrolusie and ironpyrite are reported in this article. It was found that ammonium sulfite can be used as a digesting agent which can extract sulfur efficiently from the leach residue. The effect of influence factors such as amount of digesting agent, leaching time and temperature on the extraction of sulfur has been discussed.
