And here is Bob's close up of the bubbles. The two gold lines along the back are not the particles but the reflection of lights shining down on the foam. Here is an extract from the Galantas web site which explains the process in greater detail...
"Some of the ground material is treated by gravity methods but the majority of the material, mixed with water and a small amount of foaming & flotation agents, is passed to froth flotation tanks. Here the mixture is agitated and air pushed into the mixture. The metallic minerals have a preference for air rather than water and attach themselves to bubbles. Rising to a froth, the foam is taken from the top of the cell and cleaned further by a repeat process." ©Galantas Gold Corporation
