Interface adsorption mechanism of 5-nonyl
The micro-flotation test results showed that 5-NSA produced high recovery of malachite at pH 9.0–10.0, while showing lower collecting power to calcite or quartz. The contact angle analysis results indicated that the hydrophobicity of malachite surface was promoted after the adsorption of 5-NSA.
