- •
PMHS promoted sericite flocs and enhanced sericite flotation.
- •
PMHS, a heteropolar silane coupling agent, was a superior extender oil.
- •
Direct anchor of PMHS on sericite surface benefited the aggregation of sericite particles.
- •
PMHS decreased froth stability and mechanical gangue entrainment.
- •
PMHS functioned as the collector and extender oil simultaneously.
