Panning is a type of gravity concentration used by prospectors for the recovery of gold from river beds. It concentrates the heavy gold particles at the bottom of the pan while the light gangue is washed off on top 7. • Heap Leaching • Heap leaching was introduced in the 1970''s as a means to drastically reduce gold recovery
An important characteristic is the fact that the rate of gold recovery is not affected by the agglomerate. The nature fluidity of the agglomerates allows that gold particles can be absorbed in the oil phase, which is 1227% of agglomerate. Then, rate of gold recovery is not limited by the metallic content of
