Kaolin is a non-metallic mineral material with excellent properties, which is widely used in various industries.whiteness is one of the important factors to determine its application and economic value, and the existence of iron oxide affects the whiteness of kaolin, PTMS Electromagnetic Separator kaolin iron whitening to enhance its commercial value has become the primary task.
Two different sampling points of kaolin in India contain 0.224% and 0.1% iron, and its main minerals are potassium feldspar. After PTMS Electromagnetic Separator iron removal test in a section of medium magnetic and two strong magnetic processes, feldspar with total iron content of 0.039% and 0.031%, respectively, the total iron removal rate was 82.59% and 69.00%, and its whiteness increased from 34.92 to 68.52 and 46.89 to 69.38, with good effect and achieving the purpose of iron whitening.
Iron removal microorganisms were obtained from the soil screening of the mining area, and the influencing factors of microbial PTMS Electromagnetic Separator removal in kaolin were tested. At 30% at 1%, 0.10%, 10%, from 0.94% to 0.42%.
