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.
