Much less toxic than cyanide

If you are going to use cyanide make sure that you know what your doing, it gives no second chances, it's great for recoveries but it has certain characteristics that make it deadly, do not add any acids to the mix and follow good cleanliness when using it, keep it well away from acids and be safe!

Do you mean Sodium Cyanide perhaps?

Edit: Apologies I just read the patent document. I believe there is a process using Sodium Thiocyanate which is described on the forum somewhere which appears to be a lot less toxic.
