Surface hydration of zircon and its influence on the

The adsorption of flotation reagents promoted the flotation efficiency of sulfide minerals significantly [13]. Unlike sulfide minerals, oxide minerals such as zircon, quartz, feldspar, and ilmenite are hydrophilic, meaning water can quickly form H-bonded water layers on mineral surfaces [14], [15], [16].
