Hi,

What is the optimum method to recover fine cassiterite (270 - 400 mesh)?

Thanks.

Flotation is the best option.  Gravity can work but at this size it becomes more difficult.  If gravity is an option you want to consider I would recommend a gravity recovery test using a Lab falcon.  911Met can assist with bot types of test work if you need it.

The liberation degree of our tin ore is low and tin mineral distribute relatively same in each grain size. We have conducted some test but no result can achieve our target (optimum grade and recovery).
What do you think about this case?
Thank you.

As Todd mentioned above, for -270 mesh cassiterite  that is difficult to upgrade by flotation the Falcon Continuous concentrator can be very effective. 

These centrifuges operate at up to 300Gs and can recover tin particles effectively below 20 microns (635 Mesh)
