I have a slag dump that contains various grades of Zn, Pb as well as Ga and Ge. Is there a technology or process available that can economically extract these metals? 

Thank you

Crush, grind, float, and then re-smelt the cons.

Get some good assays and treat this like a resource - figure out how much material you have and assign grades to it, then once you have done that see if it is economical to do anything - there is a reason it is in a slag pile.

Hi Todd

I have a complete CPR on the slag pile - it has been grid - drilled and assayed and which shows good grades of the above metals.

What I am now looking for is a company that has experience in the extraction of metals from slag.

Tony
