Tin tailings benefication (6 replies)

Has anyone been involved in tin-copper tailings benefication? The main challenge is to beneficate tin. Most of it (approximately 60%) are distributed in grain size -40+10 microns

We carried out several laboratory testing on gravity concentration and flotation but benefication of tin is very low. Has and anyone had such kind of experience? What kind of gravity concentrators equipment you would recommend to try? What kind of flotation reagents? Is it worth to try Falcon UF or Kelsey Jig? We haven't tried that equipment yet.

Need to know more about the gangue mineralogy.  Yes try the Falcon.  Have you done any heavy liquid separations? Also try electrostatics.

Katya,

You should take a look at or contact someone from Niu Pho project in Vietnam.  They have lots of experience in exactly what you are doing and use both flotation and gravity concentration to solve the problem.  I don't have a name right now but I am sure that you can find out who to contact there through the internet.

Peruvian tin miners are having much success using:

An Ultrafine Falcon should work well,  Given the grade you should not be expecting better than about 60% flotation recovery: see work at Renison (Tasmania) https://www.metalsx.com.au/system/announcements/825/20170704_Rentails_Update.pdf

There are options out there, as outlined above. As far as I am aware the Mozley MGS is probably best in this size range but there's other people on this forum who have a better idea about this. 

Having said that, as so often with this type of query it really pays off to have mineralogy work done to determine the PSD - metal deportment, locking, mineral types (and therefore SG). There's some pretty convincing predictive work that can be done based on mineralogy these days. Send me a PM if you want more info.

The MGS is certainly the best option for fine tin and will work a treat in the size range you are suggesting.
