I thought that was an excellent answer.
With study you learn where the value are, and how to get them separated from the trash, and prepare this for recovery of the values, then you learn to refine those values, there is no way you can explain everything there is to know about this, just too much to each method of recovery and refining, but with study you can easily learn it, although it does take time.
Start with the safety section, and dealing with waste.
Safety with these very dangerous metals, salts, gases, and acids, along with understanding how to treat the toxic waste will be generated, this should be the first thing you study and learn, getting a little gold is of minor importance to yours or others health, or safety.

Hoke's book, and reading through the forum.
When you have studied enough to get a fairly good grasp of the safety, the processes, and basic principles, a good place to begin learning in the lab is with memory fingers, and using these with what you learn from Hokes book, these can give you some of what you need to do the experiments she suggests in her book, this will make it easier for you to understand the more complicated processes latter, and prepare you for many of the principles needed to learn to recover and refine precious metals.
