  • 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.

  • Innovations in Gold Explorations Techniques

    2014-04-29  The gold mining technology in the early years was very simply. It consisted largely of manual labor and primitive tools for little to no reward.

All of these techniques use gravity and water to separate the ...

  • Gold extraction - QueensMineDesignWiki

    Once the gold ore has been removed from underground and brought to surface, an entirely new challenge begins in separating the gold from the waste material. The separation process is particularly difficult due to the usually low quantity of gold relative to waste. Common gold grades are in the same magnitude as about 5 g/t, or 0.000005% gold content by weight. This means that upgrading the ...
