I like that--thanks for the tip, Deano! I'm definitely at your "stage 1", so I might make mine a bit smaller, like a teaspoon or so.Deano said:If you dampen the metabisulfite and put it into plastic moulds used for lolly making or similar you can get dry pellets about the size of apricots.
If you add these pellets to your beaker of gold chloride one at a time the pellet will start fizzing near the surface of the liquor. As the pellet loses size it will slowly drop down to the bottom of the beaker and the bubbles will act as an agitation system for the liquor.

If anyone is interested in gold recovery please take the time to fully read and understand what he is trying to teach,
That is so true, and the minute you realize the truth in the above statement you start to get paranoid as a refiner. Whatever you do there is always some gold dissolved when you don't want it and remaining when you don't want it. A 100% yield is never possible.Deano said:Most people fail to understand that many chemical reactions are equilibrations or are slow acting or both.
These reactions are not like a switch which is either fully on or fully off.
This means that under the conditions specified the particular reaction may appear not to be happening even though chemically there is a reaction.
Often a change in conditions will drive the equilibrium further to one side of the equation or speed up the reaction or both.
