A PROCESS FOR SCRUBBING CYANIDE BEARING FURNACE GASES PRODUCED IN THE METALLURGICAL IDNUSTRY

It has been a problem that when these gases are scrubbed to remove other contaminants, the cyanide enters the scrubbing solution and thereby creates problems of subsequent safe treatment of the scrubbing solution. The solution to this problem put forward by the present invention involves making the...

Beschreibung
Zusammenfassung:	It has been a problem that when these gases are scrubbed to remove other contaminants, the cyanide enters the scrubbing solution and thereby creates problems of subsequent safe treatment of the scrubbing solution. The solution to this problem put forward by the present invention involves making the scrubbing solution more acid than usual, typically so as to prevent the cyanide ion concentration in the solution from exceeding 100 mg/litre, and then burning the scrubbed gas to remove the cyanide.
