Bioreduction of Fe(III) during caoline dispersion storage period

The efficiency of iron removal from kaolin increases with the inclusion of iron bioreduction in the technological scheme. The process can be accelerated by a combination of factors of humidity and temperature of the suspension, the state of the pH-Еh medium, the composition of the nutrient medium and inoculum from the microbial community. In the stagnant regime of the moisture content of the kaolin suspension, the bioreduction of iron is accompanied by the formation of Fe (II) -Fe (III) -containing minerals, and as a result, the reduction process stops.
