Abstract | Full Text

The releasing process of arsenic, manganese and iron from their sulfide/arsenide ores was investigated in an equipment imitating natural conditions. The experiments were carried out in flooding, trickling and pulse mode. The results showed that in flooding mode, the concentration of the studied elements in water phase was very low, but in the trickling or pulse modes it was high enough. The influence of main factors was surveyed and their effects on each element were different and were explained reasonably. The results of this paper may supplement some new data of the very common processes in nature, and they will also contribute to control and management of toxic substances which may be released into the environment.
