Abstract:
     Mineral separation for cassiterite ore comprises break, grinding, classification and the floatation for classified fine fraction less than 0.039mm. The floatation takes process of roughing for two times, scavenging for one time and refining for three times. It avoids over breaking, decreases fine ore greatly; as adding TBP, the ore needs not pre-desliming to recovery with floatation for the fine ore of less than 0.039mm. With this invention, for the cassiterite-quartz ore or tin placer with Sn content 0.6~2.0%, the flotation concentrate contains Sn more than 26%, the floatation recovery rate is more than 80%, and compared with traditional technique, the total recovery rate is increased more than 10%.
