dry iron removal equipment

Pyrite, a prevalent harmful impurity in kaolin, not only affects whiteness through its gray-black appearance but also decomposes during calcination to release SO₂ gas and Fe₂O₃, causing product yellowing and cracking. The microbial-PTMS ELECTROMAGNETIC SEPARATOR method effectively removes pyrite. Iron(II) sulfobacillus, an acidophilic autotrophic Gram-negative bacterium, operates under pH 1.5-3.0 and 28-35℃ temperatures. It utilizes atmospheric CO₂ as a carbon source while obtaining energy through the oxidation of Fe²⁺ or reduction of sulfides.

PTMS ELECTROMAGNETIC SEPARATOR

Traditional flotation or magnetic separation has low removal efficiency of pyrite, while the microbial plus PTMS ELECTROMAGNETIC SEPARATOR method can gradually transform insoluble pyrite into soluble ferrous sulfate through biocatalytic oxidation reaction, thus achieving efficient removal. The core of this technology is to construct an environment suitable for microbial growth and metabolism.

In industrial practice, enterprises prepare a suspension with a solid-to-liquid ratio of 1:5 by blending kaolin ore slurry crushed below-200 mesh. A bacterial culture solution (inoculated at approximately 10%) is added, and oxygen-rich air is introduced to maintain dissolved oxygen levels above 4 mg/L. During the initial reaction phase, a small amount of ferrous sulfate is added as a "starter agent" to activate microbial metabolic activity. The microbial-assisted PTMS ELECTROMAGNETIC SEPARATOR method effectively removes pyrite.
