Counter Current Decantation

The loss in dissolved gold per ton of dry ore for the last tank has therefore been plotted in a separate curve and it is this curve which should be given the most serious attention in determining the suitability of an ore for decantation the moisture in the pulp also has a direct bearing on the cyanide loss which is also shown in fig 5
