Industrial Applications of Tailings
Does anyone have any idea or know in which industries that discharged tailings could serve as economic raw material?
Besides gold which is our primary target, our tailings are fairly rich in Ag, Cu, Fe and Pb; but not necessarily economically viable to undertake their specific extractions via flotation or otherwise.
Subsequent to the recovery of the target gold content, via gravity concentration, we shall be left with more than 500K tons of discarded tailings.
Are there other industries in which these tailings could serve as raw material? The manufacturing of hardened/decorative blocks for construction and refractory bricks have been mentioned.
Any thoughts that can be shared on this subject would be greatly appreciated.
