I don't know enough about this to know if a 70% recovery rate is good. What is the recovery rate with current technology? This sounds promising, but can it be scaled?

It’s 99%. This doesn’t preclude that you can’t use the first method to recover 70%, and the more environmentally challenging leaching method to recovery the remaining amount. Smaller volume means it’s still a net benefit. Maybe it’s not possible after the initial processing, the paper does not discuss this.
