Is this something NCM should be doing with their tailings while the mine is running down.
“ Mine economics are often determined by a primary host
mineral. Some by-products such as gold are valuable and worth
processing. Many, though, end up in the tailings.
Companies such as Rio Tinto are now going back to
re-examine what they've been throwing away. In the case of the
company's Canadian titanium business, they found scandium,
designated a critical mineral by both the United States and
Europe.
A relatively modest $6 million investment will produce three
tonnes per year of scandium oxide - around 20% of the global
market - without the need for any additional mining.
This trend towards "whole-concept" or "total mining" is
picked up in the infrastructure bill.
The USGS is tasked with completing within 10 years a
comprehensive survey of national minerals resources, "using a
whole ore body approach rather than a single commodity approach,
to emphasize all of the recoverable critical minerals in a given
surface or subsurface deposit".
Recovery rates of all metals has been historically poor at Telfer, I remember Jim06 telling us mistakes has sent huge amounts of gold and copper to the tailings lake.
If you haven’t seen how big this lake is look on google earth and search Telfer, you can see it from way up high
I will have to find the link for that report
