Extraction of Gold and Copper from Flotation Tailings Using …
This study presents the novel idea of a cyanide-free leaching method, i.e., glycine-ammonia leaching in the presence of permanganate, to treat a low-grade and copper-bearing gold tailing. Ammonia played a key role as a pH modifier, lixiviant and potential catalyst (as cupric ammine) in this study. Replacing ammonia with other pH …

In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO. 4 ·7H. 2. O, SO. 2,Na. 2. S. 2. O. 5. and cyanide when added in excessive amounts.

Selective Flotation
On the below Chart, selective flotation (separation) is obtained from the green line (1% mass) to the red line (4.5% mass). After >4.5% mass, you get mass pull, just mass. No selectivity, no concentration. You could float all day and yes get more mass. You could float off the whole tailings if you have enough time.
