Sodium Thiosulfate

[Traveller11]

I see that sodium thiosulfate is sold as a powder that easily dissolves in water. To make a solution for leaching flour gold from a concentrate, how much sodium thiosulfate should be added to the water?
Any special techniques for leaching or is it a simple matter of adding the cons to the solution and waiting?
Has anyone come across a method for precipitating gold from sodium thiosulfate? Lazersteve mentioned something about copper sulfate...anyone?
