Method for treating high-iron bauxite

Abstract

A method for treating a high-iron bauxite is disclosed. The method includes: subjecting a high-iron bauxite to a selective crushing treatment and a classification treatment to respectively obtain a coarse-fraction bauxite and a fine-fraction bauxite; subjecting the coarse-fraction bauxite to a first gravity separation and impurity removal treatment and a second gravity separation and impurity removal treatment to respectively obtain a gravity-separated concentrate, a gravity-separated middling, and a gravity-separated tailing; subjecting the gravity-separated concentrate to a grinding treatment and a magnetic separation treatment to respectively obtain a magnetically separated concentrate and a magnetically separated tailing; subjecting the fine-fraction bauxite to an impurity removal treatment by centrifugal separation to respectively obtain a centrifuged concentrate and a centrifuged tailing; mixing the gravity-separated middling, the magnetically separated tailing, and the centrifuged concentrate to obtain a product concentrate; and mixing the gravity-separated tailing and the centrifuged tailing to obtain a product tailing.
