With improvements in flotation methods, the generally accepted procedure today is to concentrate the gold or silver bearing minerals into a small bulk and roast the concentrate only. The calcine is then usually treated in a small cyanide circuit, with the residues sometimes passing into the main cyanide circuit, if the flow sheet includes such ...

If you watch the FROTH as it comes over the edge of the float cell you will notice as each bubble flows over the edge, the bubbles behind it will move to the front of the cell. This is because as the bubble moves forward the bubble behind is attached to the front bubble by collector molecules that are attached to common particles of mineral.

95% will be material other than copper. Of the plant feed (0.5% Copper) only 42 parts per thousand weren't collected and were sent to final tails. So you can see that if you handled the concentrate, which is better than 29% copper, then handled the tails, it wouldn't take much concentrate to change the tail assay.
