How digital innovation can improve mining productivity ...

A gold mine was under severe pressure because the gold grade of the ore body it was mining had fallen by around 20 percent. The mine had increased ore-production volumes to try to offset the decline, but it was running into difficulties because this was overloading its leaching plant and incurring higher costs on energy, chemicals, and other ...

It Started With An Idea | New Gold Recovery

Present day placer mining uses pans, water and gravity, just like the prospector of 1849, only on a larger scale. This "modern" placer technology only recovers up to 40% of the gold from every ton of ore concentrate (finely ground ore) as it primarily targets nuggets and flakes of gold. The remaining 60% goes untouched.
