Process for recovering ferrochrome from chromium slag

Ferrochrome smelting slag referred to as chromium slag, solid waste produced when smelting ferrochrome alloy, these solid waste if not scientific and effective treatment, it will cause great threat to the environment and human health, while ferrochrome slag recycling Not only can it obtain certain economic benefits, but also lay the foundation for the next treatment and recycling of chromium slag.

The chromium slag contains a certain amount of ferrochrome alloy particles. The recovery of these ferrochrome alloy particles can obtain considerable economic benefits. How to recover the ferrochrome alloy particles? As we all know, a larger proportion of ferrochrome, while a smaller proportion of solid waste, recycling ferrochrome is theoretically possible from the use of chromium slag re-election law, for which we jig beneficiation ferrochrome slag depth Research and practical work, ultimately achieved very good recycling results, also proved the feasibility of the jig to recover ferrochrome.

The ferrochrome alloy in the chromium slag is wrapped in the waste slag. In order to recover the ferrochrome alloy, the ferrochrome slag must be crushed to dissociate the ferrochrome alloy from the waste slag monomer. In this state, the ferrochrome alloy particles can be recovered to the utmost extent. The machine will perform jigging and beneficiation on the crushed chromium slag, recover 8~30mm coarse-grained ferrochrome, re-pulverize the jig tailings, and recover 0~8mm fine-grained ferrochrome alloy particles. The whole process is realized. The full recovery of coarse and fine ferrochrome alloys for maximum economic benefits.

The hardness of the chromium slag is relatively large, and the first crushing process must be carried out by the jaw crusher , and the second crushing process can be carried out by using a rod mill or the like. The pulverized chromium slag can be sold to the new building materials factory to make new building materials, which basically realizes the complete recycling of the chromium slag.
