electromagnetic separator

With the growing acceptance of sustainable development concepts, emerging microbial physicochemical PTMS ELECTROMAGNETIC SEPARATOR technology is transitioning from laboratory research to industrial applications, emerging as a pivotal approach for green kaolin purification. This microbial iron removal technology harnesses the metabolic activities of specific bacterial strains to transform and eliminate iron elements. Among these, the bacterium Fe2+-oxidizing sulfur bacteria has garnered significant attention for its exceptional capacity to oxidize Fe²⁺ ions.

PTMS ELECTROMAGNETIC SEPARATOR

By optimizing the cultivation conditions —— adding 0.5% sulfur powder as energy material, controlling the temperature at 30-35℃ and introducing appropriate air for oxygen supply —— the reaction cycle can be shortened to 7-10 days, and the iron removal rate of PTMS ELECTROMAGNETIC SEPARATOR is stable at about 85%, which is especially suitable for treating sedimentary kaolin containing pyrite (FeS₂).

what is magnetic separation in Feldspar？

When microorganisms grow in sulfur-containing media, they reduce the system's pH to 2.0-2.5 through sulfur oxidation and acid production. Simultaneously, they secrete organic acids to dissolve iron minerals and oxidize Fe²⁺ into insoluble Fe³⁺ precipitates. This PTMS ELECTROMAGNETIC SEPARATOR iron removal process maintains kaolinite structure integrity, yielding products more suitable for premium papermaking fillers. Microwave-assisted technology, as an emerging physical method, demonstrates tremendous potential.
