Simultaneous multimetal leaching from industrial pyrite ash is reported for the first time using a novel bioreactor system that allows natural diffusion of atmospheric O 2 and CO 2 along with the required temperature maintenance. The waste containing economically important metals (Cu, Co, Zn As) was leached using an adapted consortium of mesoacidophilic Fe 2+ and S oxidising bacteria.

In this report, ecofriendly and lowcost pyrite tailings are utilized as denitrification materials, while pyrite and magnetite are used as the control experimental groups to explore the denitrification performance of pyrite tailings. The results show that the removal effect of pyrite tailings on NO3− is slightly lower than that of pyrite. However, the concentration of NH4+ decreased, and ...

Scraper blades, rotating with the grinding bowl, push the rejects into the reject chute and outside the mill into a bin or pyrite removal system. As the coal passes over the edge of the bowl, it becomes entrained in the rising flow of hot air. The primary air is taken from the secondary air 37 EPRI Licensed Material System Application

Electrochemical reactions result in the removal of dissolved oxygen in the closed mill system, shifting the mixed potential towards more negative values (more reducing). Forged steel is more active than 30% chrome steel, resulting in stronger electrochemical reactions with pyrite and, thereby, consuming more oxygen in the slurry.
