I would like to get feed back on safely disposing of old cyanide and chemical reagents. What is the safest and cheapest method to dispose of old chemicals such as sodium cyanide ---and old flotation reagents. are there places in British Columbia that handle this type of toxic material?

Cyanide is considered a hazardous waste product, as are most types of chemical reagents. They are subject to both your provincial waste regulations and the Transportation of Dangerous Goods (TDG) Act and Regulations.

Contact a provincially licensed transporter and/or receiver of hazardous wastes and arrange for their proper packaging, transport, and disposal.

Cheap will not be a factor as you will quickly discover after contacting waste companies. If this is in your personal possession, then contact your local municipality for the closest Household Hazardous Waste (HHW) depot.

They are many companies in BC that can receive these chemicals. Check your yellow pages for waste disposal and look for companies advertising hazardous waste. You are legally liable for ensuring proper disposal and for signing a waste manifest (which requires TDG training).

If the cyanide is still in the packages you may be able to get a metal plater to take it as cyanide is used in many plating operations. The same goes for reagents. If in the original containers and not out of date a local lab or high school may accept them. Barring that the first post says it all. Mike J.
