This study investigated the flotation in sodium dodecyl benzene sulfonate system, the effects of phytic acid on talc flotation mechanism, then proposed a new flowsheet to handle this kind talc ore, namely "one roughing-three cleaning-one scavenging". The closed-circle flotation test in laboratory can obtain a concentrate with the SiO_2 and CaO grade of the concentrate is 61.87% and 0.60%, the SiO_2 recovery is 72.59%, removal rate of tremolitei is 95.85%. This paper improved the economic value of the talc containing asbestos, laid the foundation of industrial applications.
