AFROMIX recently supplied four large Cyanide Detox Agitators to a mine in Eastern Africa. These units are able to provide high mass transfer but still able to keep the solid suspended uniformly. Sufficient air is required with SO2 gas to destroy the cyanide complex. Conventional gas dispersion systems offer good mass transfer but fail to keep the solids in suspension.
The AFROMIX system makes use of a dual sparge system which can operate with air or oxygen. The sparges have been fitted with AFROMIX’s non-return valve system which prevents the sparges from blocking even at high percentage solids.
