Abstract

An effective collector TAO for ilmenite has been synthesized.It was mixed with a cheap rape oil to be a new collector RHB for ilmenite.The flotation tests of single mineral showed that RHB had a good selectivity in fine ilmenite and titanaugite at pH=6～10.The flotation tests of mixed mineral showed that the grade of ilmenite concentrate could reach to 42.62% through single flotation using RHB as collector.The grade increased by 5.32% compared to using MOS with similar recovery.The mechanism of RHB′s key component TAO is also studied on the surface of ilmenite.
