The present invention relates to a method for simultaneously preparing porous silica and fiber. More particularly, the present invention relates to a method for simultaneously preparing natural silica concentrated in chaff shells and chaff fiber from residual substance remaining after extracting the silica. The method for preparing not only overcomes the existing difficulty of fully using and reproducing chaff, but can also efficiently simultaneously produce natural fiber in the form of pulp from wood fiber, having a cylindrical shape and a gear shape, and porous, high-purity silica with a fine structure having a large surface area, thereby significantly contributing to enhancing the utility value of chaff. |
