AI Technical Summary

Technical Problem

Existing technologies lack efficient and accurate methods and devices for iron removal during flue gas leaching, which leads to the accumulation of iron elements and affects the subsequent separation and purification of valuable metals. In particular, Fe2+ and Fe3+ are difficult to separate during molybdenum extraction, and iron in the acid leaching solution easily forms ferric arsenate crystals that clog the filter cloth pores.

Method used

A magnetic separation iron removal device for flue gas leaching process is designed, including a support frame, magnetic separation rods and scrapers. By distinguishing between magnetic and non-magnetic sections and cooperating with the scrapers, magnetic impurities are effectively removed. The device is made of acid and alkali resistant and high temperature resistant materials to ensure stable operation in complex environments.

Benefits of technology

This technology achieves high efficiency and ease of operation in the magnetic separation process, effectively removes magnetic impurities from the acid leaching solution, ensures the smooth progress of subsequent valuable metal extraction processes, and extends the service life of the equipment.
