Removal of Arsenic from Tin concentrates (3 replies)

I have recently been reading about using froth floatation instead of roasters to rid tin concentrates of Arsenic. Has anyone have experience or theories on the best way to go about it. What kind of collector would be best recommended. Anyone used the Jameson cell?

 

Patrick.

Hello Patrick, what form is the Arsenic in? Is it associated/locked with your Tin? Where are you in terms of testing or is this just a hypothetical situation?

Hi Patrick

If you have a look online for flowsheets for Renison Mine in Tasmania, they recover cassiterite from a sulphide host by doing a sulphide float and rejecting the sulphide concentrate - this includes arsenopyrite. I am assuming you have a similar mineralisation, rather than dealing with a stannite ore? There are actually a few places that do this I think, I am just most familiar with Renison.

The attached image was a screenshot from the Google Books version of Handbook of Flotation Reagents: Chemistry, Theory and Practice: Volume 2 By Srdjan M. Bulatovic. If you can hunt this down, it has an excellent section on cassiterite flotation describing collectors at various operations.

Assuming you have a deposit/mine in mind, the best thing to do is to contact Glencore Technology directly to ask if they have done any work on your type of ore using Jamo's. If you do have a specific ore in mind, then you are going to have to do testwork, and probably a pretty extensive series, if you are thinking of going this route. First step, as MillMan has suggested, would be to get a really good idea of your mineralisation and liberation requirements.
