In recent years, the ore grade has deteriorated by a problem that contains a large amount of impurities. The impurities containing minerals have similar structures and properties to typical minerals. Therefore it is difficult to separate from the target mineral. Sulfide ore is the specific mineral of non-ferrous metals, and collectors are the core technology of the comprehensive recovery of sulfide ores. In order to improve flotation efficiency for complex sulfide ore, novel flotation collectors need to be developed. This study considers the possibility of recovery improvement of sulfide ores without significantly changing the conventional production process. We focused on synthesizing several compounds that can be developed as collectors and used them for the flotation of sulfide ore under different conditions to test their flotation properties. And for comparison, flotation of conventional collectors such as Xanthate under the same conditions was also investigated.
