Electronic properties of sulfide minerals and floatability. Jianhua Chen, ... Ye Chen, in Electronic Structure and Surfaces of Sulfide Minerals, 2020. 2.6.1 Introduction. Sulfide ore flotation is a complex electrochemical system. Electron transfer not only occurs between the sulfide minerals and flotation reagent molecules, but it also happens among different sulfide minerals.
Nickel is an important raw metal material in industry, which has been identified as a strategic mineral resource by the Chinese Ministry of Land and Resources. Nickel sulfide ore accounts for 40% of all nickel ores worldwide. However, magnesium silicate gangue minerals in sulfide nickel ores, particularly serpentine, pose significant challenges to the flotation of nickel …
The copper ore flotation method can be divided into forward flotation and reverse flotation according to the separation of valuable components: discharging useless minerals (gangue minerals) in the slurry as tailings are called forward flotation. Otherwise, it is called anti-flotation. Copper is one of the important non-ferrous metals. In the production process, the …
