Cyanide Control in Mining with Wet Air Scrubbers

scroiler

Cyanide is a naturally occurring substance found in various elements of nature, including fruits, nuts, plants, and insects. It is used in multiple industries safely and without harming the environment despite its toxicity.

Cyanide serves as a valuable industrial chemical, with more than one million tons utilized each year in areas like electroplating, metal processing, manufacturing organic chemicals and plastics, as well as in photography. Gold mining processes utilize cyanide to dissolve and separate gold from ore. A previous method of gold ore separation involved the use of liquid mercury; the cyanide gold extraction a is a much safer process.

Despite the safety of the process, the cyanide itself is highly toxic to humans, especially in large doses. Exposure to cyanide causes suffocation, which may result in death if left unattended. Long-term exposure to cyanide can cause cassava and depressed thyroid function. Due to the severe negative health effects of cyanide, appropriate air pollution control methods and techniques need to be implemented in facilities where cyanide is used.

Cyanide can also occur as a byproduct of the gold mining leach process in the form of hydrogen cyanide. Scroiler™ was used to absorb HCN at a gold mining facility. The earlier wet air scrubbers employed by the client relied on pure concentrated Calcium Hydroxide, which is overly costly. Moreover, due to the frequent clogging of the wet scrubber, the Calcium Hydroxide was not used efficiently, which led to an increase in the scrubber upkeep costs.

The old wet air scrubbers were replaced with Scroiler™s which provided the same air treatment quality as traditionally used wet air scrubbers utilizing lime milk instead of Calcium Hydroxide. Scroiler™ can utilize low-quality cleaning liquid that can be prepared on-site and contain small rocks of lime.

Scroiler™ is a new type of wet air scrubber that is devoid of many wet air scrubber’s drawbacks while operating at the same efficiency. Scroiler™ can replace any wet air scrubber as a whole, and in some cases, we can use old scrubber – primarily it’s body – as a basis for a Scroiler™ system. A new type of wet scrubber, Scroiler™ cleans air from gases, dust, vapors and other admixtures using water or other cleaning liquid. Scroiler™ produces the cleaning mist differently from other scrubber systems, which results in running costs that are much lower than for a common wet scrubber.
