Cyanide - NaCN dosage in Flotation

An aspect very important is the NaCN dosage. Even, having a slight excess of activated carbon, the right addition depresses chalcopyrite. However, an excessive addition will make black froths and very heavy. The overdosage can be necessary when the zinc content in the bulk copper concentrate is more than 10%. Thus, for the conditioning tank the addition can be 45 to 50 % of the total dosage. The idea is has a residual cyanide for the next cells and consequently make small additions en last cells. This dosage can be 4 to 5 kg/t_bulk. See Figures 10 and 11.
