Surface sulfidization mechanism of cuprite and its response to xanthate adsorption and flotation performance

The flotation recovery of cuprite is unsatisfactory because of its natural hydrophilic surface, which decreases the flotation index of copper concentrate. One can modify the cuprite surface by sulfidization to create a hydrophobic surface that is more favorable for flotation. Therefore, it is necessary to reveal the surface sulfidization mechanism of cuprite to efficiently recover cuprite resources. In this work, we used Na2S to modify the...
