Abstract: Barite is an important strategic non-metallic mineral. China has rich barite resources. Its reserves, output and export volume rank first in the world. However the situation of low export price has existed for a long time. Based on the characteristics of barite ore at the present stage, this paper introduces the different dressing methods of barite ore in China. The types, characteristics and application status of collectors and inhibitors in the process of barite flotation were reviewed. The factors affecting the quality of the flotation concentrate were analyzed. The methods of chemical purification and whitening of barite were discussed. It is pointed out that the preparation of barite with high purity and whiteness and the increase of product added value will be one of the important ways to realize the efficient utilization of resources.
