Chromium is a solid waste produced when smelting iron-chromium alloy, these waste if not through scientific and effective treatment, it will cause great harm to the environment. The ferrochrome smelting slag contains a small amount of ferrochrome alloy particles, and the recovery of these granules can obtain considerable economic benefits and lay the foundation for the further treatment of the chromium slag. The ferrochrome smelting slag is generally dry slag, and the ferrochrome alloy particles are unevenly embedded. In order to separate these ferrochrome alloys, it is necessary to first break up the large pieces of chromium slag into small pieces to achieve the basic monomer dissociation of ferrochrome alloy and solid waste slag. In this state, the ferrochrome alloy and the solid waste slag are dissociated from the monomer in a specific form, and a simple process is used to separate the ferrochrome alloy particles from the waste slag to achieve the purpose of sorting. It is well known that chrome-iron alloy particles as an alloy have a density much larger than these solid wastes similar to stones. Therefore, the solid waste residue can be separated from the ferrochrome alloy particles by a simple re-election process to achieve the purpose of sorting. The re-election method is a method of sorting according to the difference between the density of minerals and waste rock. The larger the difference in specific gravity, the better the sorting effect. The re-election equipment used for the selection of chromium slag is mainly a jig and a shaker. The jig is used for selecting coarse, medium and fine-grain mineral materials. The shaker can only select fine-grained materials, while the larger the ferrochrome alloy is. The higher the price, the many investors want to get the largest possible ferrochrome particles. This requires selective crushing when re-crushing, retaining large pieces of ferrochrome alloy particles as much as possible, entering a large-grained jig for sorting, sorting out large pieces of ferrochrome, and then granulating the ferrochrome Further crushing, fine ferrochrome particles were selected.
