Left image – microscopy photo of panned Knelson concentrate. Right image – HG composite Panned Knelson concentrate. Seen in the images are the grains of visible gold, electrum, and copper bearing minerals, likely covellite, malachite and azurite. Copper minerals are in generally low abundance and not deleterious to recovery.
