Apr 24, 2010 You need enough alum for it not to dissolve completely even when the solution is warmed. You might need as much as 20% by weight to achieve this. i.e. 4 grams of alum in 20 ml of water. As I recall my mother used a saturated solution when pickling cucumbers but that was 65 years ago and I was not paying that much attention.

Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zinc is added to precipitate out residual zinc as well as the silver and gold metals.
